%X Soil enzymes are the biochemical catalysts of soil nutrient cycle.Research efforts on enzymological mechanisms of soil nutrient cycle are vital in evaluating the state of soil nutrients in the piedmont region of North China Plain(NCP).The objectives of the study were to investigate: i) the distributions of soil enzyme activity in the soil profile and ii) the correlations between soil en-zyme activity and nutrient content of different particle-size fractions.The soils were collected from long-term field expe...
