Farmers must embrace technology to
move forward in business. That’s the view of a Wiltshire father and son
whose family has farmed the same land since the 1920s. Andrew Blake reports.
Patrick Hosier and son George who run
Wexcombe Manor Farm have been
pleasantly surprised during their first stab
at IPF field zoning.
Their 620ha (1550 acre) arable and beef
unit was bought during the agricultural
depression between the two World Wars.
“Our aim is to keep going as a family
business and to pass on the estate in an
economically and environmentally
enhanced state,” says George.
“Technology is there to allow us to
make savings, take the right
decisions and hopefully improve
yields. We need science to help us
keep up.”
Patrick agrees. “With grain and
commodity prices going up you can
guarantee that the cost of most of
our inputs – fertiliser and everything
else – will follow,” he says.
Commercial aspects must come first,
both men acknowledge; but the
environmental side of their business
is also clearly close to their hearts. A
10-year Countryside Stewardship
scheme ended two years ago and
the farm is now under HLS.
“We’ve planted a lot of woodland
since the 1970s, and we have a
private shoot,” says Patrick.

UPCOMING ISSUES • Spring 2011 -Looking forward to new Nitrogen planning on the IPF Toolbox. -Looking at biomass and LAI data with soil zones. -Variable Seedrate planning and implementation.
• Summer 2011 -Yield Maps on the IPF Toolbox. - Farmer Focus. - Soil Protection Review.
INDEPENDENT JOURNALISM We believe our independence as a business is one of our main strengths. We are delighted to have independent articles provided by Andrew Blake. Andrew has worked as an agricultural journalist for 24 years concentrating mainly on arable crops. He managed arable farms before taking up journalism giving him ideal experience for contributing to this magazine.
IPF CARBON CALCULATOR We are very proud that IPF farmers are helping reduce CO2e emissions. We will display in every addition of Zoning Matters just how much potential CO2e has been saved. We estimate: 5.500 tonnes of C02e will collectively be saved during 2011 year by IPF farmers. A typical 400 ha arable farm using the IPF service saves 44 tonnes of C02e per hectare per annum. Be proud and market your low carbon farming system.
LIFE SHOULD BE FUN - Farm diversification!! This farmer had completed all the relevant NVZ paperwork and was not in breach of any closed periods. Anyone for a cold glass of Coca-Cola??

FORWARD LOOKING FARMERS EMBRACE IPF TECHNOLOGY

The Courtyard Partnership has a new website! Lots of new useful information can be found and downloaded. All editions of zoning matters are available to read in soft copy if required. Visit; www.courtyard- partnership.co.uk
PROFESSIONAL DEVELOPMENT
Free inline tuition is available for all IPF Toolbox users. An interactive conference can be used to help clearly communicate training via the internet.
The land has a wide range
of soil types, from
greensand on the lowest
areas, through different
depths of chalkland to flinty
chalks and clay cap on the
highest ground.
For many years base
fertiliser policy has been
based on the Courtyard
Partnership’s sampling and
analysis of a third of the
farm each year for
phosphate, potash,
magnesium and pH plus
other elements where
deemed necessary.
Corrective dressings,
originally as 0:30:20 or
0:18: 36 blends according
to soil type. Now, with a
move to variable rate
spreading, straights – triple
superphosphate (TSP) and
muriate of potash (MOP) –
have then been applied in
the autumn.
Their latest move to more
precise farming, via
Courtyard’s IPF zoning
system, came only after
several years and
discussions with
independent agronomist
Steve Cook, says George.
“He has no axe to grind.
I’ve been to quite few
meetings over the past
three or four years and built
up a background
knowledge of the different
approaches.
“We were keen on both the
SOYL and IPF systems.” In
the end the decision to stick
with Courtyard was mainly
because it was likely to be
cheaper in the long run
without sacrificing any
precision, he explains. “But
we’d also been with the firm
for a long time.”
“Part of the shift to
precision involved fitting
the main drilling, spraying
and top-dressing New
Holland T7050 tractor with
GPS equipment”
comments George.
Today’s main crops include
winter-sown wheat, barley
and oilseed rape, plus
spring barley for malting,
the latter usually confined to
the lighter land.
Linseed, beans and peas
have all failed to find
permanent slots, but
George hopes that hard red
spring wheat, provided a
contract can be gained this
season, could be become a
useful workload-spreading
crop.
The farm also has a 60-cow
single suckler herd to graze
some steep unploughable
permanent pasture, and
there is a small area of
temporary grass, recently
reduced by HLS arable
reversion.
“The soils within our fields
are very variable,” says
Patrick.
The land has a wide
range of soil types,
from greensand on
the lowest areas,
through different
depths of chalkland to
flinty chalks and clay
cap on the highest
ground.

ASK GEEVES !
What’s new for the IPF Toolbox
OS Mapping : (inc- Buildings, Roads, Trees, Water, Monuments, Railways)
HGCA Varieties: We have introduced the HGCA data for all crops to the
Toolbox. This provides vital information about each crop and will encourage future development at a crop specific level.
Custom Rulesets: Allows you to create a specific strategy for each crop
variety, includes variable nitrogen planning.
RB209 8th Edition: All new nutrient management plans are now created
using the new RB209 8th Edition. Product color coding; All products can now given colors to help
highlight details on reports.
The ASK GEEVES page is back! With developments on your IPF Toolbox happening at break-neck speed this section keeps you up to date with all new developments. As a company we are very lucky and proud to have Mike Geeves & the team at AxiomTech
Solutions Ltd develop your website. His skills in IT management and software development
are not common in agriculture. Mike has worked for Siemens, Nokia and Ericsson, all
international companies developing at the cutting edge of technology.
Mike is very excited about the development of
high resolution satellite imagery because it will
provide a 3rd dimension to the IPF Toolbox.
“Having a system that can layer precision data
will provide a valuable management tool into the
future” says Mike.
Mike is also expecting a new addition to his family
during January. We hope this will add even more
development to the IPF Toolbox, as soon as Mike
completes the baby training!!
By the time this autumn’s
spreading was completed
they had 32.9t of MOP and
36t of TSP unapplied and
still in store. “At
September’s prices that’s a
saving of £23,000,”
calculates George.
Zoned application can be a
disconcerting act of faith,
admits Patrick.
“For much of the time the
spreader is spreading
nothing!” One 27ha field of
black puffy soil needed just
0.6t of TSP, he notes.
“The proof of the pudding
will come next harvest,”
says George. “But at least it
means we already have
some cheap fertiliser in
store for next year.”
Part of the shift to precision
involved fitting the main
drilling, spraying and top-
dressing New Holland
T7050 tractor with GPS
equipment and, in
partnership with
neighbours, installing an
RTK base station. The
combination means driving
is accurate to +/- 2cm, he
notes.
The whole farm was also
mapped into IPF zones
according to soil types, the
maps indicating P, K, Mg
indices and pH by
Courtyard soil scientists.
“We had an initial meeting
with Courtyard’s Vince
Gillingham to show him
where we thought the soil
changed within our fields.
The IPF Scientists then
assessed every field in
autumn and spring cropping
and drew up the maps. We
then had another meeting
and were basically happy
with them.”
Most striking was how high
the nutrient indices were,
but just as surprising were
the recommendations that
followed via Courtyard’s
online IPF Toolbox, notes
Patrick. These are
downloaded to a data card
and fed, via a Trimble
Nomad handheld computer,
to the electronic controller
on a new £14,000 Kuhn
Axis 2.5t mounted
spreader.
“They came as quite a
shock, showing how little
fertiliser we were going to
have to use.”
All inputs are purchased
through the Crop Advisors
buying group, and fertiliser
is usually bought forward.
“This season, before the
IPF mapping, we’d worked
out what we thought we’d
need, which was 56 tonnes
each of MOP and TSP.”

NITROGEN TESTING SPECIAL OFFER
*** 25% DISCOUNTED NITROGEN TESTING***
IPF subscribers planning variable nitrogen applications this spring can take advantage of our
discounted nitrogen sampling service. Using our experienced soil sampling team, samples
will be taken using GPS equipment and stored in cooling boxes for same day laboratory
delivery.
An accurate way of measuring soil nitrogen is to sample for soil mineral nitrogen at 0-30 cm
and 30-60 cm. This method can cost £95.00 per sample using other services.
We are offering the SMN service at £69.50 per sample a 25% discount. If more than 10 samples are taken additional discounts are applied.
N helps you decide on accurate N rates for each zone and will increase the efficiency
of fertiliser usage and decrease potentialleaching. SMN testing is normally carried out
during February; this sampling period provides you with the most accurate data possible for
the growing crop.
.
IPF service subscribers already get large discounts on our annual services but in every Zoning Matters issue we will have further offers on relevant products and services.

RB209 - 8th EDITION UPDATE The IPF Toolbox has been updated with all the new changes in the RB209 8th Edition. The revision of the former Fertiliser Recommendations for Agricultural and Horticultural Crops (RB209 7th edition) to create the updated Fertiliser Manual has been led by Rothamsted Research, North Wyke Research and Warwick-HRI, compiling information from many sources, and with guidance from various Steering Groups.
We have removed the hassle and confusion from updating yourself with all the various
changes. The IPF Toolbox now has comprehensive coverage with new updates for all arable
and vegetable crops.
The major updates in the 8th Edition of RB209 are;
Soil Nitrogen Supply (SNS) Index system
Revised nitrogen recommendations
Updated organic manures section
New approach to grassland recommendations
New recommendations for biomass crops
Potatoes
Sugar Beet
Sulphur recommendations
Phosphate & potash recommendations These updates will make differences to the Nutrient Management Plans provided on the IPF
Toolbox. Although some changes are minor and may not be noticed. If anything has changed
that you are uncomfortable with, please discuss with one of our FACTS qualified advisors.
Grassland Recommendations; We are still developing the Grassland Recommendation section in the 8th Edition. The
grassland section on the IPF Toolbox will be updated during 2011.The current grassland
recommendations are still accepted and can be used in the meantime.
system has involved HLS.
Under their new
stewardship scheme,
introduced in September
2009, the Hosiers have
taken several field corners
out of production, sowing
them with various seed
mixtures, some intended to
provide pollen and nectar
sources for insects and
others to feed wild birds.
“They’re mostly 1ha
corners, although we do
have some 2ha stone
curlew plots,” says Patrick.
“But my striding out clearly
wasn’t good enough. With
the GPS mapping element
we’ve been able to
measure those areas much
more accurately and so
avoid any downgrading
after inspection.”
“Overall we think it’s
well worth it,”
comments George.

We are pleased to announce that from spring 2011 you will be able to receive high resolution crop canopy mapping integrated with your IPF Toolbox information.
For the first time in the UK this will allow farmers to see biomass data overlaid onto soil maps,
which will bring two major advantages.
1. For the first time it will be possible to see crop growth data combined with soil type
maps, making it easy to understand the ‘why’ of variation, rather than just identify that
variation exists.
2. Different soil types will perform more or less successfully depending on the crop and the
weather in any given season. This service will make it possible to better understand how
each field is performing during the current season.
We will be offering three different types of crop map, which will each serve a different purpose:
Ground Cover Map; This is useful in early season, to identify variation in establishment.
This additional information can then be used in future seasons to improve variable seed
rate decisions
NDVI Map; This map shows plant vigour, using a combination of crop leaf area and
greenness. This map is useful during intermediate stage of growth, specifically around
the time of first and second N dressings for winter crops.
RECOMMEND A FRIEND AND EARN CASH-BACK FOR YOUR FARM.
We are amazed at how much work has been generated over the past few years by kind
recommendations from existing IPF customers. In recognition of your support we are
pleased to offer £1.00 per hectare to all IPF subscribers who introduce us to a new customer
not currently using the IPF service. **
There are no catches; for example if you introduce us to someone farming 400 hectares who
zones their whole farm and signs up to the IPF service we will issue you a £400 credit note!
If you would like to participate in this scheme, please contact Vince Gillingham on 01793
421345 or 07905 266 403 to let us know who you would like to introduce to the benefits of

service.
IMPORTANT INFORMATION FOR 2011 SPRING ZONING
Although the weather has been cold we have been able to complete over 10,000 hectares of
IPF zoning this autumn. This progress has been better than expected and has created an
additional surplus of 4,000 hectares available to be IPF zoned during the spring.
If you have additional land you wish to zone this spring please let us know as soon as
possible and we can organize the zones ready for spring applications.
Please contact one of the team and we will be happy to come and collect all relevant data.
Relative Chlorophyll Maps; There is a
close correlations between nitrogen status
and chlorophyll content of a plant.
Understanding this will show how
effective earlier N applications were.
These maps will also make variable late
foliar applications possible, giving you the
best chance of meeting protein targets in
Milling Wheat. We will be releasing further details of exactly how
this service will operate closer to the time, but you
can be sure that we will be aiming to produce
something which is highly efficient, but keeps you
Reliable coverage with x5 satellites

Above; Potassium deficieny in oilseed rape
MAGNESIUM
Magnesium plays central role in photosynthesis,
and plant chlorophyll; Mg is a carrier of
phosphorus in the crop and has functions in many
enzymes. Crop demand for magnesium is
relatively small compared to nitrogen and
potassium.
RB209 advises application of magnesium
fertilisers when Mg index is below 1.5 especially
for sensitive crops such as oilseed rape, potatoes
and sugar beet. Oilseed rape crops should be
targeted in the rotation if Mg deficiency is found.
If the soil is acidic and Mg fertiliser is required,
magnesium limestone can be applied if cost
effective. 5 t/ha of magnesium limestone contains
about 750 kg MgO/ha. However, when Mg index is
above 3, there is a high risk of potash deficiency.
Be aware of IPF soil code M, which is for soils over
magnesium limestone.
Accurate nutrient management planning will
improve crop quantity and quality; reduce farming
cost and environmental risk. Economic volatility
and pressures from climate change legislation
make careful planning vital.
POTASSIUM
Crop demand for potassium requirement can be
very large. Potassium is important for crop
photosynthesis, carbohydrate transport, water
regulation and protein synthesis. Potassium
applications improve disease resistance, drought
tolerance and winter hardiness. K also increase
vegetative growth and decrease the risk of
lodging.
Potash can be leached from soils that are free
draining. Stoney and sandy soils are at highest
risk of K leaching. Many clay soils release
potash, Chalky boulder clay, Gault clay, Weald
clay, Kimmeridge clay, Oxford clay, Lias clay and
Oolitic clay all release differing amounts of K.
Up to 50 kg/ha of potash can be released
annually on certain soils. Be aware of IPF soil
code G, which is a potash-releasing clay.
Your Potash index should be maintained at 2, for
sandy soils it can be maintained at index 1+ (100
mg/l) this is due to lower clay content resulting in
less potash holding capacity.
Be aware of IPF soil code F, H, R and S with
suffix 0.5 or 1, these are all sandy soils and may
need regular applications to maintain a
satisfactory index .
Nitrogen By Elena Kasyanova, PhD/Msc and Bsc in Soil Science
Under the microscope:
Phosphate, potash and magnesian fertilisers
are commonly used in conventional British
farming. Often 1/3 of the cost in growing a
cereal crop goes in fertiliser. Recent released
data on agricultural soils analysed between
June 2009 - May 2010 from NRM shows that
17% of soil P indexs and 29% of soil K Indexs
were below target level; in other words, nearly a
quarter of UK farmland P&K levels are below
optimum.
PHOSPHORUS
Crop demand for phosphorous is low compared
with nitrogen and potassium, however,
phosphorus is critical for early crop growth,
especially in root development, fruiting and
energy transfer. Phosphorus in the plant is
mainly concentrated in the seed and fruit.
A deficiency of phosphorus affects vegetative
growth, seed formation and overall yield. At
very low or high pH P can be ‘fixed’; acidic soils,
P reacts with iron and aluminium oxide then
becomes unavailable; in calcareous soils, P
reacts with calcium and forms sparing calcium
phosphates.
IPF soil codes map high risk P fixing soils, be
aware of soil codes C, H, F, G and S, these are
all potentially acidic and P fixing, very calcareous
soil codes such as E or A codes with a suffix k
can also fix phosphate.
Soils formed from sand often have more
available phosphate. When we statistically
analysed our IPF soil analysis database upper
greensand soils had a high average P index.
P index should be maintained at index 2 or
above. Building the soil P index can be a long
process, raising 1 index (10 mg/l) can take 850
kg/ha of TSP. The use of organic forms of
phosphate can often raise the soil index quickly.
Sewage sludge and chicken manure is
particularly efficient at raising P indexs.
6 7
Accurate P, K & Mg management planning is important when keeping levels at an optimum. To achieve this we advise the following: a) Regular soil sampling
and analysis
b) Maintain levels at the
target index
c) Appropriate application
timing to increase
effectiveness.
d) Accurate nutrient
budgeting.
e) Accurate organic
manure records and
applications.
OPTIMUM APPLICATION TIMING…
Phosphate = Autumn
Potassium = Spring
Magnesium = Spring
By applying your
ferrtiliser when the crop
needs it most will result in
better utilization and
lowers the risk of losses.
BE AWARE… The following IPF soil
codes are potentially P
fixing;
A (Chalk & Limestone)
C (non-calcareous soils)
E (Chalk Marl)
G (deep clays)
Y (alluvial soils)
W (Marine alluvium)
Any codes with a k suffix
are very high risk as these
codes have high pH 8.0+
Be prepared to soil
analyse the above soil
codes every 3 years.
Maintaining an optimum P
level on these soils is key
to overall yield.

Determined to pass on the estate in an economically and
environmentally enhanced state.
RB209 - 8th EDITION UPDATE The IPF Toolbox has been updated with all the new changes in the RB209 8th Edition. The revision of the former Fertiliser Recommendations for Agricultural and Horticultural Crops (RB209 7th edition) to create the updated Fertiliser Manual has been led by Rothamsted Research, North Wyke Research and Warwick-HRI, compiling information from many sources, and with guidance from various Steering Groups.
We have removed the hassle and confusion from updating yourself with all the various
changes. The IPF Toolbox now has comprehensive coverage with new updates for all arable
and vegetable crops.
The major updates in the 8th Edition of RB209 are;
Soil Nitrogen Supply (SNS) Index system
Revised nitrogen recommendations
Updated organic manures section
New approach to grassland recommendations
New recommendations for biomass crops
Potatoes
Sugar Beet
Sulphur recommendations
Phosphate & potash recommendations These updates will make differences to the Nutrient Management Plans provided on the IPF
Toolbox. Although some changes are minor and may not be noticed. If anything has changed
that you are uncomfortable with, please discuss with one of our FACTS qualified advisors.
Grassland Recommendations; We are still developing the Grassland Recommendation section in the 8th Edition. The
grassland section on the IPF Toolbox will be updated during 2011.The current grassland
recommendations are still accepted and can be used in the meantime.
system has involved HLS.
Under their new
stewardship scheme,
introduced in September
2009, the Hosiers have
taken several field corners
out of production, sowing
them with various seed
mixtures, some intended to
provide pollen and nectar
sources for insects and
others to feed wild birds.
“They’re mostly 1ha
corners, although we do
have some 2ha stone
curlew plots,” says Patrick.
“But my striding out clearly
wasn’t good enough. With
the GPS mapping element
we’ve been able to
measure those areas much
more accurately and so
avoid any downgrading
after inspection.”
“Overall we think it’s
well worth it,”
comments George.
George and the team preparing the New Holland T7050 tractor and Kuhn Axis 2.5t mounted spreader for a busy day variable rate fertiliser spreading.
By the time this autumn’s
spreading was completed
they had 32.9t of MOP and
36t of TSP unapplied and
still in store. “At
September’s prices that’s a
saving of £23,000,”
calculates George.
Zoned application can be a
disconcerting act of faith,
admits Patrick.
“For much of the time the
spreader is spreading
nothing!” One 27ha field of
black puffy soil needed just
0.6t of TSP, he notes.
“The proof of the pudding
will come next harvest,”
says George. “But at least it
means we already have
some cheap fertiliser in
store for next year.”
Part of the shift to precision
involved fitting the main
drilling, spraying and top-
dressing New Holland
T7050 tractor with GPS
equipment and, in
partnership with
neighbours, installing an
RTK base station. The
combination means driving
is accurate to +/- 2cm, he
notes.
The whole farm was also
mapped into IPF zones
according to soil types, the
maps indicating P, K, Mg
indices and pH by
Courtyard soil scientists.
“We had an initial meeting
with Courtyard’s Vince
Gillingham to show him
where we thought the soil
changed within our fields.
The IPF Scientists then
assessed every field in
autumn and spring cropping
and drew up the maps. We
then had another meeting
and were basically happy
with them.”
Most striking was how high
the nutrient indices were,
but just as surprising were
the recommendations that
followed via Courtyard’s
online IPF Toolbox, notes
Patrick. These are
downloaded to a data card
and fed, via a Trimble
Nomad handheld computer,
to the electronic controller
on a new £14,000 Kuhn
Axis 2.5t mounted
spreader.
“They came as quite a
shock, showing how little
fertiliser we were going to
have to use.”
All inputs are purchased
through the Crop Advisors
buying group, and fertiliser
is usually bought forward.
“This season, before the
IPF mapping, we’d worked
out what we thought we’d
need, which was 56 tonnes
each of MOP and TSP.”

NITROGEN TESTING SPECIAL OFFER
*** 25% DISCOUNTED NITROGEN TESTING***
IPF subscribers planning variable nitrogen applications this spring can take advantage of our
discounted nitrogen sampling service. Using our experienced soil sampling team, samples
will be taken using GPS equipment and stored in cooling boxes for same day laboratory
delivery.
An accurate way of measuring soil nitrogen is to sample for soil mineral nitrogen at 0-30 cm
and 30-60 cm. This method can cost £95.00 per sample using other services.
We are offering the SMN service at £69.50 per sample a 25% discount. If more than 10 samples are taken additional discounts are applied.
N helps you decide on accurate N rates for each zone and will increase the efficiency
of fertiliser usage and decrease potentialleaching. SMN testing is normally carried out
during February; this sampling period provides you with the most accurate data possible for
the growing crop.
.
IPF service subscribers already get large discounts on our annual services but in every Zoning Matters issue we will have further offers on relevant products and services.

“They came as quite a
shock, showing how
little fertiliser we were
going to have to use.”
The land has a wide range
of soil types, from
greensand on the lowest
areas, through different
depths of chalkland to flinty
chalks and clay cap on the
highest ground.
For many years base
fertiliser policy has been
based on the Courtyard
Partnership’s sampling and
analysis of a third of the
farm each year for
phosphate, potash,
magnesium and pH plus
other elements where
deemed necessary.
Corrective dressings,
originally as 0:30:20 or
0:18: 36 blends according
to soil type. Now, with a
move to variable rate
spreading, straights – triple
superphosphate (TSP) and
muriate of potash (MOP) –
have then been applied in
the autumn.
Their latest move to more
precise farming, via
Courtyard’s IPF zoning
system, came only after
several years and
discussions with
independent agronomist
Steve Cook, says George.
“He has no axe to grind.
I’ve been to quite few
meetings over the past
three or four years and built
up a background
knowledge of the different
approaches.
“We were keen on both the
SOYL and IPF systems.” In
the end the decision to stick
with Courtyard was mainly
because it was likely to be
cheaper in the long run
without sacrificing any
precision, he explains. “But
we’d also been with the firm
for a long time.”
“Part of the shift to
precision involved fitting
the main drilling, spraying
and top-dressing New
Holland T7050 tractor with
GPS equipment”
comments George.
Today’s main crops include
winter-sown wheat, barley
and oilseed rape, plus
spring barley for malting,
the latter usually confined to
the lighter land.
Linseed, beans and peas
have all failed to find
permanent slots, but
George hopes that hard red
spring wheat, provided a
contract can be gained this
season, could be become a
useful workload-spreading
crop.
The farm also has a 60-cow
single suckler herd to graze
some steep unploughable
permanent pasture, and
there is a small area of
temporary grass, recently
reduced by HLS arable
reversion.
“The soils within our fields
are very variable,” says
Patrick.
The land has a wide
range of soil types,
from greensand on
the lowest areas,
through different
depths of chalkland to
flinty chalks and clay
cap on the highest
ground.

Farmers must embrace technology to
move forward in business. That’s the view of a Wiltshire father and son
whose family has farmed the same land since the 1920s. Andrew Blake reports.
Patrick Hosier and son George who run
Wexcombe Manor Farm have been
pleasantly surprised during their first stab
at IPF field zoning.
Their 620ha (1550 acre) arable and beef
unit was bought during the agricultural
depression between the two World Wars.
“Our aim is to keep going as a family
business and to pass on the estate in an
economically and environmentally
enhanced state,” says George.
“Technology is there to allow us to
make savings, take the right
decisions and hopefully improve
yields. We need science to help us
keep up.”
Patrick agrees. “With grain and
commodity prices going up you can
guarantee that the cost of most of
our inputs – fertiliser and everything
else – will follow,” he says.
Commercial aspects must come first,
both men acknowledge; but the
environmental side of their business
is also clearly close to their hearts. A
10-year Countryside Stewardship
scheme ended two years ago and
the farm is now under HLS.
“We’ve planted a lot of woodland
since the 1970s, and we have a
private shoot,” says Patrick.

INDEPENDENT JOURNALISM We believe our independence as a business is one of our main strengths. We are delighted to have independent articles provided by Andrew Blake. Andrew has worked as an agricultural journalist for 24 years concentrating mainly on arable crops. He managed arable farms before taking up journalism giving him ideal experience for contributing to this magazine.
IPF CARBON CALCULATOR We are very proud that IPF farmers are helping reduce CO2e emissions. We will display in every addition of Zoning Matters just how much potential CO2e has been saved. We estimate: 5.500 tonnes of C02e will collectively be saved during 2011 year by IPF farmers. A typical 400 ha arable farm using the IPF service saves 44 tonnes of C02e per hectare per annum. Be proud and market your low carbon farming system.
LIFE SHOULD BE FUN - Farm diversification!! This farmer had completed all the relevant NVZ paperwork and was not in breach of any closed periods. Anyone for a cold glass of Coca-Cola??
