Biochar phosphorus fertilizer effects on soil phosphorus availability

Chemosphere, 2020
Biochar is a potential material for making slow-releasing phosphorus (P) fertilizers for the sake of increasing soil P use efficiency and mitigating P losses. However, the long-term effects of P-laden biochars on soil P availability remains unconcerned.

Phosphorus in recycling fertilizers - analytical challenges

Environmental Research, 2017
The importance of secondary raw materials for phosphorus (P) fertilizer production is expected to increase in the future due to resource depletion, supply risks, and heavy metal contamination of fossil phosphate resources. Municipal wastewater is a promising source for P recovery. In Germany for instance, it contains almost 50% of the total amount of P

Optimum Phosphorus Fertilization

1985
A model is developed relating economic phosphorus fertilizer application rates to soil phosphorus content and crop and phosphate prices. Optimum rates are relatively low for soils with moderate to high phosphorus content. For most Corn Belt soils, phosphate fertilizer demand is price elastic.
