- Abstract:
-
The soil microbial biomass carbon (SMBC) and soil microbial biomass nitrogen (SMBN) in latosolic red soil at Yunnan Pupiao were investigated to determine how they were affected by tillage and fertilization. The results showed that different tillage and fertilization on soil microbial biomass carbon and nitrogen were affected. The effects of tillage on soil microbial biomass carbon and nitrogen were consistent, and showed no tillage > tillage. The influence of fertilization on soil microbial biomass carbon in 0—20 cm was tillage fertilization > tillage, 20—40 cm and 40—60 cm were tillage > tillage fertilization, while effect of fertilization on soil microbial biomass nitrogen contrasted with the effect of microbial biomass carbon. The quotients of soil microorganism were significantly different (p<0.05) in different tillage and fertilization and soil depth, and showed no tillage > tillage. Effect of tillage fertilization on soil microbial quotient of the 0—20 cm was slightly higher than tillage, and the other soil layers were tillage > tillage fertilization. The ratio of soil microbial biomass nitrogen to total nitrogen was similar to the trend of soil microbial biomass nitrogen. In different tillage and fertilization, no tillage would improve the soil microbial biomass helpfully, also fertilization could improve the soil microbial biomass in a certain extent.
