Abstract

Biochar is a product produced during the Thremolysis of organic compounds under anaerobic conditions or without air. Biochar contains high carbon content when applied to the soil increases the ability to absorb and retain water in the soil and supply back to the plant during drought time. When it combined with fertilizer, especially with organic fertilizer (manure) will increase the effect of fertilizer on crops, improve soil moisture, help plants tolerate drought better. This is evidenced by the results of studying the effects of biochar combined with manure on leafy vegetables and rice in sandy coastal areas of Ha Tinh, Quang Tri, and Quang Nam provinces. As a result of this study, applying biochar at the rate of 2.5 - 5.0 ton/ha for leafy vegetables and rice can partially replace or completely replace manure for coastal sandy land in study areas. Applying biochar in combination with manure with the rate of 2.5 ton biochar + 10 ton manure showed a remarkable increase in efficiency, when Combined applying of biochar with organic fertilizer significantly increased the yield of Green mustard by 54-65%, cabbage yield by 38.4% and rice yield from 15.4 to 27.9% compared with control treatment.
