Effects of combined application of compound fertilizer and biochar on absorption and utilization of phosphorus by wheat.

ABSTRACT: Unreasonable fertilization practices are still applied in agricultural production, resulting in reduced crop yields and wasting resources. Therefore, it is essential to optimize fertilization regimes to improve the nutrient absorption capacity of crops. However, the effects of combining nitrogen, phosphorus, and potassium (NPK) compound fertilizer with biochar on the uptake and utilization of phosphorus (P) by wheat and soil fertility remain poorly understood. Thus, we tested three biochar levels (0 quintal (q) ha^-1 (B1), 75 q ha^-1 (B2), and 150 q ha^-1(B3)) and four compound fertilizer levels (0 q ha^-1 (F1), 2.25 q ha ^-1(F2), 4.50 q ha^-1 (F3), and 6.75 q ha^-1 (F4)), and compared the effects of different experiment
