The results showed that red soil microbial biomass P was closely related with soil total P, soil organic P and soil rapidly available P. Relative coefficients were 0.840, 0.897 and 0.944, respectively. Especially, the significant relation of red soil microbial biomass P to soil rapidly available P suggested that red soil microbial biomass P may act as an indicator of P-supply ability. Greenhouse incubation expriments showed that red soil microbial biomass P was also closely related with ryegrass dry matter yield, ryegrass P uptake and P uptake per unit weight of ryegrass. Relative coefficients were 0.789, 0.895 and 0.910, respectively, which indicated that P plant-availability of red soil microbial biomass P was not only reflected on ryegrass dry matter and plant P uptake,but also more obviously reflected on P uptake per unit weight of plant.

Organic-inorganic compound fertilizers were applied to 2 neutral purple soils in Chongqing to study their effects on the yield and nitrogen recovery of the rice crop and on nutrient content in the soil. The results showed that plant height, flag leaf area and spike length were enhanced and the percentage of unfilled grains decreased by the application of organic-inorganic compound fertilizers. The 40% fermented organic-inorganic fertilizer treatment appeared optimum, in which paddy grain yield increased by 2.5%~10.1%...

Organic-inorganic compound fertilizers were applied to 2 neutral purple soils in Chongqing to study their effects on the yield and nitrogen recovery of the rice crop and on nutrient content in the soil. The results showed that plant height, flag leaf area and spike length were enhanced and the percentage of unfilled grains decreased by the application of organic-inorganic compound fertilizers. The 40% fermented organic-inorganic fertilizer treatment appeared optimum, in which paddy grain yield increased by 2.5%~10.1% and nitrogen recovery by 17.65%. Paddy grain yield decreased with increase in organic N in the compound fertilizer. Application of organic-inorganic fertilizer in two successive years resulted in marked increase in available P and K in the soil, the increase range being greater as the proportion of organic N in the compound fertilizer increased. No conspicuous change in available N in the soil was observed in the study. The variation in CEC was similar to that in available P and K.

Effect of different levels of N and P on availability of Zn, Cu, Mn and Fe under arid conditions was studied. Results showed that the content of available P increased in loamy soil by application of N and P under the content of soil water (11%~14%), and content of soil available P decreased with the depth of soil increase. Application of P could increase the available Zn, Cu and Mn contents, on the contrary, for iron. The coefficient of correlation was 0 65, and -0 63 between available P and Zn , and...
