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.
