Plant nutrition remains the key to successful agriculture. Correcting soil deficiencies, like phosphorus, sulphur, nitrogen and potassium are essential for highest possible yields of pasture and crop for any environment. More fertile soils, as a consequence of correcting soil deficiencies, is also an important part of having the highest soil quality.
Fertilisers like urea, superphosphate, MAP and DAP, often referred to as conventional products, are frequently by far the cheapest way to correct deficiencies. Conventional fertilisers commonly contribute to adding to soil organic matter via their effect on greater plant biomass, including root systems. Animal manure, such as poultry or feed lot, can equally correct soil deficiencies plus supply some organic matter.
