Application of biological carbon in vegetable production ( field experiment )
Abstract: As the ceaseless developing science and technology that the bio-chai applying technique has been continuously expanded towards each one of science areas and also have a marked impact on agriculture. As be one of bio-organic with multiple inter-space and a greater proportion of surface that bio-char has its special character to ameliorate the soil structure and biochemical features.This experiment is aimed to bringing out new production that has the function of improving efficiency through organically combine bio-char with fertilizer Contrast experiment of the fungal feeding compounds fertilizer and N-P2O5-K2O as starter treatment in distributing manure over fields.Comment the influence in bio-chemical character of soil which has caused by experimental subjects. The result indicates that Bulk density reduce 0.3-0.5 per unit and moisture content increase 0.5-1.0 percentage, nitrogen content increase 0.6-0.7 ppm, phosphorus content increase 100-200 ppm. Vitamin and minerals in vividly rising up which content in vegetables. This experiment enough to prove that bio-char has its special character to ameliorate the soil structure and biochemical feature, enhance the quality and production simultaneously.
