Dynamics of soil P pool in a long-term fertilizing experiment of wheat-maize rotation Ⅰ. Crop yield effect of fertilizer P and dynamics of soil total P and inorganic P

Abstract

Abstract: The effects of long-term applying fertilizer P and manure on the pools of soil total P and inorganic P and the crop yield in rotation of winter wheat-summer maize→spring maize were studied. The results showed that the pool of soil total P and inorganic P were increased by applying fertilizer P and manure, and the phosphorus mostly accumulated in soil was inorganic P. The critical amounts of fertilizer P (P₂O₅) for balancing soil P were 94.7 kg·hm^-2 to winter wheat-summer maize and 51.5 kg·hm^-2 to spring maize. Based on regression equations, the application rates of fertilizer P (P₂O₅) for economic optimum and highest yields were 135.8 and 149.8 kg·hm^-2 to winter wheat-summer maize, and 88.6 and 95.9 kg·hm^-2 to spring maize, respectively.

Key words: Effect of fertilizer P, Changes of soil phosphorus pool, Long term experiment, Rotation of winter wheat spring maize→spring maize, trade-off., cavitation resistance, ring-porous wood, hydraulic conductance, diffuse-porous wood
