Losses of phosphorus (P) from fertilized fields may result in degradation water quality. Various initiatives are under evaluation to minimize contamination, including the adoption less soluble or coated P fertilizer formulations aiming mitigate losses runoff. Field-based rainfall simulators traditionally used evaluate runoff, but using these is time consuming, labor intensive, and costly given ...

Essential plant nutrients contained in residues and wastes generated during biofuel processing can be recovered for further production of bioenergy biomass. The objective of this study was to determine the relative agronomic efficiency of “processed” biofuel residual (PBR). Liquid biofuel residual was “processed” by precipitating phosphate and ammonium in the residual with magnesium into a stru...

BACKGROUND Blind and excessive application of fertilizers was found during the cultivation of Panax notoginseng in fields, as well as increase in root rot disease incidence. METHODS Both "3414" application and orthogonal test designs were performed at Shilin county, Yunnan province, China, for NPK (nitrogen, phosphorus, and potassium) and mineral fertilizers, respectively. The data were used ...

Despite phosphorus resources on Earth being limited, over fertilization in many agricultural situations causes significant resource consumption. Phosphorus-recycling within production can reduce global dilution into the environment and is thus essential to secure sustainable future supply. This study investigated efficacy of fertilizers recycled from biogas digestates maize shoots grown under c...
