The regression analysis results of rate of fertilizer, amount uptaken by crops and accumulation of soil nutrients in the localized trial of fertilizers on wheatcorn on yellow fluvo-aquic soils during 1981—1986 showed that 8.76% of chemical fertilizer-N and 42.54% of organic fertilizer-N entered into soil N pool, 17.61% of chemical fertilizer-P and 17.20% of organic fertilizer-P into soil available P pool, and 4.5% of chemical fertilizer-K and 2.3% of organic fertilizer-K into soil available K pool.

The regression analysis results of rate of fertilizer, amount uptaken by crops and accumulation of soil nutrients in the localized trial of fertilizers on wheatcorn on yellow fluvo-aquic soils during 1981—1986 showed that 8.76% of chemical fertilizer-N and 42.54% of organic fertilizer-N entered into soil N pool, 17.61% of chemical fertilizer-P and 17.20% of organic fertilizer-P into soil available P pool, and 4.5% of chemical fertilizer-K and 2.3% of organic fertilizer-K into soil available K pool. Chemical fertilizers tended to increase in organic matter content of the soils, while significantly good effect of organic fertilizers was found on supplementing soil nutrients such as P and K and improving soil physical properties. Combined application of chemical and organic fertilizers was effective both in promoting soil fertility and raising crop yield.

red soils differing in fertility levels were tested to study the relationships between soil microbial biomass P and soil P or P plant-availability. 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.
