WebMuch of the phosphorus is farmed out of the mountains in the form of phosphate. * Peak phosphate is expected within 25 years (Rock production). Most common form of soluble phosphate is diammoniumn phosphate. Fertilization of crops leads to a lot more P runoff relative to natural flux of P in natural systems. Weband lakes is agricultural runoff (nonpoint source P runoff). Poultry litter applications to pastures have been shown to result in relatively high P runoff, even when litter is applied at recommended rates (Edwards and Daniel, 1992a,b, 1993). Most of the P (80 to 90%) in the runoff is in the soluble form (Edwards and Daniel, 1993),
WebThe natural phosphate levels of the various soil types are low. Additional fertilization is then necessary. However, too much accumulation of phosphate in the soil, for example on agricultural land, leads to phosphate leaching and runoff to the surface water. This is bad for water quality (e.g. algae growth) and biodiversity.
