Process and assessment of organic substrate production by cassava stalk compost

In this study cassava stalk as main material, was used to transform into organic substrate with auxiliaries of chicken manure, sugarcane bagasse and fermenting bacteria of organic waste. The experiment was conducted aimed at probing the best process of fermentation and evaluating the quality of substrate. The results indicated that the main indexes of substrate, including composting temperature, total carbon (TC), total nitrogen (TN), value of TC divided TN, pH, total phosphorus (TP), total potassium (TK), and electrical conductivity (EC) showed some regular changing trends. Physical and chemical properties of substrate were suitable for cultivation. Treatment 2 (stalk of cassava + fermenting bacteria of organic waste + chicken manure) and treatment 3 (stalk of cassava + fermenting bacteria of organic waste + chicken manure + sugarcane bagasse) were more appropriate for organic substrate production considering the effect on composting temperature, composting duration and physical chemistry indexes of soilless planting substrate.
