Biochar is sterile, odorless, high carbon solid that can be produced from a variety of organic feedstock. Soil application of biochar can reduce the overall total BD of the soil which is desirable for most plant growth and increased WHC. Nutrient availability can be affected by increasing CEC, altering soil pH, or direct nutrient contributions from biochar. The soil fertility of course texture is poor, so biochar application improved soil fertility of sandy loam soils, especially soil having low O.C., CEC, available P, exchangeable K, Ca, Mg and increased nutrient uptake resulted in increased in crop yield.
• Application of corn stover biochar @ 10 t ha-1 along with RDF increased DM and CP yield, chlorophyll content and plant height (at 30 and 60 DAS) as compared to CB and PJ biochars and FYM.
• Nutrient uptake like P, K, Ca, Mg, S and Cu were significantly increased with the application of RDF+MS10 while in case of uptake of N and Mn were significantly increased in RDF+MS5.
• RDF+MS10 was found most effective in obtaining significantly higher DMY and CPY and larger removal of nutrients from the soil and found beneficial for built up nutrients in soil. It also showed significantly higher CEC and OC content in sandy loam soil.
• Application of RDF+MS5 significantly increased DMY and CPY content of forage corn crop which ultimately resulted in larger removals of nutrients from the soil.
