Table 1 Results of ANOVA (Analysis of variance) on the effects of experimental site (St), cotton growth stage (S), treatment (T) and their interactions on WSOC/SOC, MBC/SOC, WIN/TN, MBN/TN and MBC/MBN ratios, cellulose-decomposing bacteria amounts (CDBA), cellulase (CE), β-glucosidase (β-GE) and arylamidase (AE) activities

From: Comparative effects of crop residue incorporation and inorganic potassium fertilization on soil C and N characteristics and microbial activities in cotton field
