Última Soil enzyme activities under long-term tillage and crop rotation systems in subtropical agro-ecosystems BJM Balota,Elcio Liborio; Kanashiro,Miriam; Colozzi Filho,Arnaldo; Andrade,Diva Souza; Dick,Richard Peter. Agricultural practices that reduce soil degradation and improve agricultural sustainability are needed particularly for tropical/subtropical soils. No-tillage planting causes minimal soil disturbance and combined with crop rotation may hold potential to meet these goals. Soil enzyme activities can provide information on how soil management is affecting the potential to perform the processes in soils such as decomposition and nutrient cycling. Soil enzyme activities were investigated in a split-plot experiment (3 replications) where tillage (no till and conventional) was the main plot and crop rotation (soybean/wheat, S/W; maize/wheat, M/W or cotton/wheat, C/W) was the subplot. The experiment was established in 1976 in southern Brazil. Soil samples were...
