Abstract

The paper is based on the research results carried out in a long term trial placed on an eroded soil in 1999 at the Station for Agricultural Research and Development from Oradea. The experiment had three monitored factors (crop rotation, organic fertilization, annual chemical fertilization) and in 2012 after winter wheat harvesting there were prelevated soil samples from the depth of 0-10 cm, 10-20 cm, 20-30 cm. The actual and potential dehydrogenase activity, the catalase activity, the acid and alkaline phosphatase were determined. The usual methods were used for determination. Enzymological activity decreased according with increase of the depth. In the variant without organic fertilization were determined the smallest values of the enzymological parameters, the biggest values were determined in the variant with manure 50 t/ha. Both manure and green manure determined bigger values of the enzymological parameters studied than the etalon. Using a mixture of Lupinus angustifolius oat rape as green manure there were determined bigger values of the enzymological parameters compared to the the use of Lupinus angustifolius in pure crop. Also using the mixture recommended by the biology school (vetch oat ryegrass) the enzymological parameters were bigger then Lupinus angustifolius in pure crop but smaller than the values determined in the variant with the mixture of Lupinus angustifolius oat rape. The mixture of Lupinus angustifolius oat rape is recommended.

Keywords: green manure, manure, dehydrogenase, catalase, phosphatase
