EFFECT OF IRRIGATION ON THE BIOLOGY OFSOIL
Journal Title: Natural Resources and Sustainable Development - Year 2013, Vol 3, Issue 1
Abstract
Soil enzyme activities are the direct expression of the soil community to metabolic requirements and available nutrients. A short field assay was established to study the potential of soil biological parameters as early and sensitive indicators of the effects of agricultural practices on soil properties. We have determined five enzymatic activities (actual and potential dehydrogenase, catalase, acid and alkaline phosphatase) and one nonenzymatic catalytic activity (H2O2 splitting in autoclaved samples) in the 0–10–, 10–20– and 20–30–cm layers of a preluvosoil submitted to a complex irrigation and crop rotation (2– and 3–crop rotations) experiment. Non-irrigation – in comparison with irrigation – resulted in significantly higher soil phosphatase activities in the 0–10–, 10–20– and 20–30–cm layers, whereas dehydrogenase and catalase activities were significantly higher in irrigated soil. The soil under wheat or maize was more enzyme-active in the 3– than in the 2–crop rotation and in the monoculture. In the monoculture and in the 2–crop rotation, higher enzymatic activities were registered for wheat followed by maize. In the 3–crop rotation, higher enzymatic activities were recorded maize after wheat. The enzymatic indicators of soil quality decreased depending on the nature of crops and kind of irrigation in the following order: maize (3–crop rotation) > wheat (3–crop rotation) > wheat (2–crop rotation) > maize (2–crop rotation) > wheat (monoculture) > maize (monoculture).
