This work was carried out to evaluate the alterations in organic-C, microbial-C and in the activities of the enzymes cellulase and amylase in soil samples of a Rhodustalf collected in the summer at 0-10, 10-20 and 20-30 cm depths, under natural forest (NF), 20 (P20) and 25 (P25) year old pastures and 10 year old cotton cultivation. Organic-C and microbial-C contents and the amylase and cellulase activities were very similar in NF, P20 and P25. Reduction of 18% in organic-C […]
