The soil environmental index(SEI),which is a four digit code system,represents relatively homogenous spatial unit with specific soil capacity to provide ecologi
At elevated temperature regimes and abundant precipitation,mobilization and accretion of weathered iron oxides are promoted especially in a reduced environments in the tropics.This may lead to the for
An 80-d incubation experiment was conducted to investigate straw decomposition,the priming effect and microbial characteristics in a non-fertilized soil(soil 1) and a long-term organic manure-fertiliz
Amino compounds(ACs),i.e.,amino acids and amino sugars,are the major forms of organic nitrogen(N)in animal manure and soil.To increase our understanding on the effect of long-term poultry litter(PL)ap
A laboratory-based aerobic incubation was conducted to investigate nitrogen(N) isotopic fractionation related to nitrification in five agricultural soils after
