WebLeaching of nutrients (Nl) Most of the literature on nutrient leaching is confined to information on point observations for N and K, which are variable and difficult to extrapolate. The literature reveals that N leaching can be predicted reliably in an African environment on the basis of information on rainfall, soil moisture content and nutrient content of the soils. Web7 mei 2013 · Clays and organic soils hold nutrients and water much better than sandy soils. As water drains from sandy soils, it often carries nutrients along with it. This condition is called leaching. When nutrients leach … In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Soil structure, crop planting, type and application rates of fertilizers, and other factors are taken into account to avoid excessive nutrient loss. Leaching may also refer to the practice of applying a small … Meer weergeven Nitrogen is a common element in nature and an essential plant nutrient.
