Abstract: Modern agriculture is leading mining of nutrients and reduction in soil organic matter levels through repetitive harvesting of crops. Declining fertility status of soil is now becoming primary concern for growing of the crops. This decline of the soil continues until management practices are improved, additional nutrients are applied, rotation with nitrogen fixing crops is practiced, or until a fallow period occurs allowing a gradual recovery of the soil through natural ecological development. Soil health is the foundation of a vigorous and sustainable food system. Plants obtain their nutrition from organic matter and minerals present in soils. As the land is cultivated, the agricultural process disturbs the natural soil systems including nutrient cycling and the release and uptake of nutrients. As the natural stores of the most important nutrients for plant growth decline in the soil, growth rates of crops are inhibited. The most widespread solution to this depletion is the application of soil amendments in the form of fertilizers containing the three major nutrients: nitrogen, phosphorus, and potassium. Among these nutrients, nitrogen is considered the most limiting for plant growth. Nitrogen builds protein structures, hormones, chlorophyll, vitamins, and enzymes, and promotes stem and leaf growth. Biochar may be added to soils with the intention to improve the soil health, improve soil fertility, and sequester carbon. However, the variable application rates, uncertain feedstock effects, and initial soil state provide a wide range of cost for marginally improved yield from biochar additions, which is often economically impracticable. The need for further research on optimizing biochar application to improve crop yields.
