Description

Biochar may sequester carbon in the soil for centuries or even millennium, it may provide nutrients as promoters of plant growth, it may reduce soil GHGs emissions and nitrate migration towards groundwater, it may improve the physical and chemical characteristics of soil, thereby supporting soil biology, and it may immobilize soil pollutants, thereby protecting plants from mobile contaminants.The biochar response is higher in sandy loam type of soils as compared to heavy soils like silt loam or black soils. It suggested that sandy or sandy loam soils having poor soil fertility due to low organic carbon is more responsive to biochar. Biochar production followed by soil incorporation could provide humanity carbon farming solutions to global climate change and escalating food demand. There is evidence to suggest that biochar amendment causes fundamental changes in soil nutrient cycles, often resulting in marked increases in crop production, particularly in tropical infertile soils with low soil organic matter contents. Several studies indicated that biochar has a long life in soil and is more effective in sequestering carbon besides improving other soil properties like CEC, retention of nutrients, WHC, soil aeration and nutrient availability. Corn stover biochar showed its superiority by producing higher dry matter and crude protein yields of corn crop as compared to cluster bean stover and Prosopis julilifera wood biochar. It also showed more positive significant response for higher uptake of nutrients in presence of recommended chemical fertilizer as compared to alone biochar in the soil. The soil physical as well as chemical properties has been improved. There was saving of one irrigation in sandy loam soils due to increase of WHC of the soils. The better aeration due to reduction of bulk density so more growth of micro-organism.
