Soil Enhancement and Effect of Biochar on the Growth of Soybean (Glycine max L.)

Biochar production is a technology that traps atmospheric-carbon and adds to soils to form carbon sinks. Biochar endures in soils and helps mitigate climate change. It can be derived from sources like agricultural waste, forest by-products, and industrial/ municipal waste. Despite the existence of comprehensive literature, it is desirable to know more about physicochemical properties of biochars. Thus, this work is divided into two objectives: 1) to conduct a review on biochar used as a soil amendment, and 2) to present results based on an experimental study in which different sources of biochar were used to enhance the properties of a sandy- loam soil. The second objective, looks at the characterization of biochar in terms of morphology & physicochemical properties in relation to soil amendment, using the case of two cultivars of soybean. The need to establish mitigation strategies is vital before climate changes proceeds.
