Declining soil fertility is a major constraint limiting African agriculture. In a four-year (2007–2011) on-farm study in Malawi, we compared the effects of compost (bokash and liquid manure) and compost (bokash) in combination with low doses of inorganic fertilizer with recommended inorganic fertilizer rates on the performance of three maize genotypes. Compost use resulted in increases in soil organic carbon, total nitrogen, available phosphorus, and soil pH. Chemical analysis of both bokash… CONTINUE READING
