- Horticultural practices that affect soil fertility
- Mechanical Operations (ploughing etc)
- burying exhausted surface layers and replaces with deeper richer layers
- burys weeds and crop remnants which can then rot
- Aeriates soils
- Overworking soil can damage structure
- Liming
- Causes fine clay soils to clump (Aeriates soils)
- Neutralises acids in water logged soils
- Untitled
- Chemical Fertilisers
- Adds fresh minerals to soils. N more important
- Added as Chile saltpetre or ammonium sulphate
- Does not improve soil structure and ultimately damages soil
- Adds fresh minerals to soils. N more important
- Organic Fertiliser
- Has all correct nutrients for plant growth
- Rots to humus, helping soil texture
- gives body and moisture retention to sandy soils and clumps clay soils
- Crop Rotation
- Crops rotated, left fallow or grass / clover sewn to increase N
- Mechanical Operations (ploughing etc)
