Fatty‐Acid Profiles and Enzyme Activities in Soil Particle‐Size Fractions under Long‐Term Fertilization

Core Ideas Organic treatments significantly enhanced soil organic C, total N, and most enzymes activities. The highest soil organic C, total N, and enzyme activities were existed in 200‐ to 63‐μm fraction. Soil organic C, total N, C/N ratio, α‐glucosidase, sulfatase, β‐glucosidase, β‐cellobiohydrolase, and phenol oxidase activities were significantly correlated with phospholipid fatty acids. A long‐term experiment was established in 1981 to...
