Phosphomonosterase and dehydrogenase activities in a horticulture soil under integrated and organic management

Abstract

The effect of integrated and organic management on the levels of dehydrogenase and alkalyne phosphomonosterase (EC 3.1.3.1) activities was determined in a horticultural soil during a four year crop rotation, finding no statistically-significant differences. Since soil tillage and fertilization were similar, the absence of effects suggests that the well-reasoned use of small rates of agrochemicals in the integrated management for weed and pest control may have negligible effects on soil microbiological activity.
