2026-08-20 Impact of vineyard inter-row cover crops on soil organic carbon fractions doi:10.57760/sciencedb.cjae.00318 en The total nitrogen (TN), nitrate nitrogen (NO3-- N), ammonium nitrogen (NH4+- N), total phosphorus (TP), available phosphorus (AP), available potassium (AK), and total organic carbon (TOC) in the soil were determined using the method proposed by Bauerstein. Soil dissolved organic carbon (DOC) was determined using K2SO4 leaching TOC analyzer, microbial biomass carbon (MBC) was determined using chloroform fumigation K2SO4 leaching TOC analyzer, and easily oxidizable organic carbon (ROC) was determined using 333 mmol · L-1 potassium permanganate oxidation colorimetric method. Fluorescence microplate method was used to determine the activities of β - glucosidase (β G), α - glucosidase (α G), β - xylosidase (β XYL), cellulase (CBH), N-acetyl - β - D-glucosidase (NAG), leucine aminopeptidase (LAP), and alkaline phosphatase (ALP).  vineyard; soil organic carbon; inter-row cover crop; soil nutrient; soil enzyme activity jing yi ze Wang Junye Zhang Haiyan Cao Jianhong Li Yuqiang Wang Xuefei Xizhumei RESTRICTED dataset Science Data Bank
