Biochar and conventional compost reduce hysteresis and increase phosphorus desorbability in iron mining waste

Phosphorus (P) fixation in the soil reduces utilization of this element by plants and can be one main problems for fertilization management soils containing Fe oxides. As a strategy to minimize effects P retention, organic materials, such as biochar or commercial composts, may useful tools maintain availability delay immobilization soil, thereby benefiting, example, rehabilitation areas impacted mining. The objective [...]
