Characteristics of releasing nutrition for slow urea nitrogen fertilizers at maize seedling stage;

The amounts of urea nitrogen,nitrate nitrogen,ammonium nitrogen and available nitrogen of slow/controlled release nitrogen fertilizers were monitored at the maize seedling stage.

The amounts of urea nitrogen,nitrate nitrogen,ammonium nitrogen,soil urease enzyme,nitrate reduetase activities,microbial biomass carbon and nitrogen of using slow/controlled release fertilizers was monitored at the maize seedling stage.

The effects of chemical fertilizer on nematode community composition and diversity were investigated in a field throughout the corn growing season in the Black Soil Region, Northeast China.

The dynamic changes of soil microbial biomass Carbon (C) and soil enzyme activities during growth of corn were studied in field experiment.

The dynamic changes of soil enzyme activities during growth of corn,in particular,the relationship of soil enzyme activities with the contents of soil nutrients were investigated based on a 12-year long-term fertilizer experiment in Fluvo-aquic soil in Changping County,Beijing,China.
