✦ Synopsis

Microbial populations and enzyme activities in a soil amended with sewage sludge in a long-term field experiment were studied in relation to the decomposition of organic matter. Two kinds of sewage sludges were applied to the soil at rates of 50 and 100 tons~ha~ year for 8 years. The percentage of humic acids increased in the soil with the application of sewage sludges. The enzyme activities exhibited a high correlation coefficient with the number of microorganisms and the content of humic substances. The results suggested that the sewage-sludge application increased microbial activity in the soil, contributing to the gradual decomposition of organic matter.

Four sewage sludges (SL) with different origins were selected from the A Β΄vila region (Spain). Sewage sludge 1 (SL1) was primary sewage sludge without biological stabilization, sewage sludge 2 (SL2) and sewage sludge 4 (SL4) were obtained after anaerobic stabilization and sewage sludge 3 (SL3) was c
