SOILS
AND AGRICULTURE
Loss
of nutrients and organic matter from the soil is generally caused by
cultivation. Some fertilizers such as ammonium sulphate promotes
acidification and compensates for loss of lime. Fertilizers and grass
seed are used to replenish the soil that is, "pasture
improvement". Compaction and sealing of the surface can be
caused by heavy stocking, implements, and cultivation. Soil erosion
is caused by water and wind after land has been overstocked, over
cropped, over cleared or infested with pests such as rabbits.
