Ammonium sulphate

and the environment


2/17

Your report should include the

following: An explanation of why ammonium

sulphate is a good fertiliser An explanation of what algae are and what

photosynthesis and respiration are

An explanation of what happens iffertilisers are allowed into the water

Definition of EUTROPHICATION(VLE)

and an explanation of what it is. Advice on how we should dispose ofammonium sulphate

Facts and pictures!

Fertilisers

Ammonium Sulphate is a good fertiliser asit contains Nitrogen and Sulphur which areboth needed for healthy plant growth

Without Nitrogen and Sulphur a plantcannot make the amino acids in proteinsthat are needed for plants to grow

Fertilisers can make all plants grow evenwhere you do not want them to.


4/17

Ammonium sulphate provides

the plant with;-NitrogenSulphur.

These are needed to makeproteins so the plants can growbigger.

The fertilizer needs to be

dissolved in water so the plantcan take it in through the roots.

Fertilizers make plants grow better increasecrop yield

With Fertilizer Without Fertilizer


6/17

As fertilisers dissolve in water the rain

can wash them out of the soil and into rivers

and streams.

Farmers spray their crops with fertilisers


7/17

Algae

In most rivers there are ALGAE.

Algae are simple plants which are made

up of one or 2 cells

They contain chloroplasts and they canphotosynthesize and respire


8/17

Algal Bloom If fertiliser is accidentally released into a water

ecosystem the algae will thrive.

The added Sulphur and Nitrogen fromammonium sulphate allows the algae to grow

and multiply rapidly This is called an Algal Bloom

10/17

The Effects of an Algal Bloom The green algae covering the surface stop sunlight reaching

under the water, so aquatic plants underneath cantphotosynthesize and will die.

The algae also respire at night and remove all the oxygen fromthe water so animals such as fish die.

The plants and fish underneath die and decay The river becomes dead.


11/17

Photosynthesis

Photosynthesis is the process by whichgreen plants, use the energy from

sunlight to produce sugar,The equations for

photosynthesissymbol equation:

6 CO2 + 6 H2O C6H12O6+ 6 O2

word equation:

carbon dioxide + water glucose + oxygen


12/17

Respiration

Aerobic respiration is the release of energy

from glucose or another organic substrate in

the presence of Oxygen

Eutrophication

What is eutrophication?When a body of water has too many nutrientsin it, we say thateutrophication has occurred. Higher than natural nutrient levels can

cause plant growth, especially the growth of algae. Algae remove oxygen

from the water, which makes it difficult for other plants and animals to get

enough oxygen to survivehttp://www.environment-agency.gov.uk

There are lots of definitions of eutrophication on the

VLE Remember to put the website!!

Using Ammonium Sulphate

Must be handled carefully to stop it gettinginto the streams and rivers and causingdamage to the environment.

How do we store and use it?

How do we dispose of it?


16/17

Guidelines for Fertilizer Use

Prevent additional discharge of material, if possible to doso without hazard.

Prevent spills from entering sewers, watercourses,wells, etc. Product will promote algae growth and

may degrade water quality and taste. Notify downstream water users. Sulphate in potable

drinking water should be maintained below 500mg/L.

Will dissolve and disperse in water. Reclaiming materialmay not be viable. Recover and place material insuitable containers for recycle, reuse, or disposal.Ensure disposal is in compliance with governmentrequirements and local regulations.

17/17

Disposing of fertilisers

Recycle wherever possible. Whatever cannot besaved for recovery or recycling should be sent toan approved waste disposal contractor fordisposal in an approved waste facility.

Normally product is suitable for disposal atan approved landfill site. Processing, use orcontamination of this product may change thewaste management options. Care should betaken to ensure compliance with national and

local regulations. This product is NOT for disposal via

municipal sewers, drains, natural streams orrivers.
