TRAMPLING(stressed byovergrazing)

SHALLOW COMPACTION DEEP COMPACTION

• Randomtraffic onthe field

Heavyloads

Lightloads

• Controlledtraffic inthe field

Break platy structure

Subsoilerparaplow

Crop rotationwith strong root crops

(e.g. oilseed radish)

Agro-forestry

Minimum tillage

Plant deep rooting cropsto naturally crack the soil

(e.g. maize and alfalfa)

Leave plant rootsto decomposeinside the soil

Optimize pH and add organicmatter for soil structure formation

• Avoid working the soil when wet • Work the soil when dry

OPTIMAL GRAZING• Rotate the grazing area• Reduce the number ofanimals per unit area

REMOVAL• For animal feed

• For fuel production (also biofuel)

• Tillage

MAINTAIN AND/OR INCREASE• Crop rotation• Manure and compost application• Keep the soil covered• Minimum tillage/zero tillage

• Avoid slipping while driving

let’s see what the

main causes of soil compaction are and

how to prevent it from

happening

DEEP COMPACTED SOILS ARE THE

MOST DIFFICULT TO REMEDIATE

What to do if your

soil is already compacted ?
