Utilization of crops residues as compost and biochar for improving soil physical properties and upland rice productivity
The abundance of crops waste in the agricultural field can be converted to organic fertilizer throughout the process of composting or pyrolysis to return back into the soil. The study aimed to elucidate the effect of compost and biochar application on the physical properties and productivity of upla...
