Abstract
Biochar rice husks and cow manure as soil amendment have the potential to improve soil chemical properties such as soil pH, CEC, and several compounds such as C-organic, N-total and can fertilize the soil. This research is the third planting season, continued from the previous two planting seasons. The purpose of this study was to determine the effectof residual soil amendment in the third planting season on soil chemical properties, yield potential and protein content of soybean seed. From this research, the residue of soil amendment in the first planting season and the addition in the second planting season showed values that were not much different in each treatment both from the chemical nature of the soil and protein content. Soil pH, P-available and CEC tends to increase in residual cow manure 20 tons ha-1 and 10 tons ha-1 but not significant. Likewise with the potential for large yields in cow manure residues of 20 tons ha-1, another case with the highest crude protein content obtained in the control (R1) (without the soil amendment or fertilizer).
