Abstract

The paper is based on the research results carried out in a long term trial placed on the Agricultural Research and Development Station in 1999. The soil from research field is erosioned one, with 10% slope. Two components of the sustainabile agrciculture system were studied crop ratation and organic fertilization. Crop rotation studied: winter wheat-maize; oat clover-maize-winter wheat-maize. The variants with organic fertilization studied: control (without fertilization), Lupinus angustifolius, Lupinus angustifolius oat rape; vetch oat ryegrass; manure, 25 t/hectare; manure, 50 t/hectare. In 2013, the soil samples after winter wheat from the first crop rotation were prelevated. Results research regarding the soil physical properties … indicate an improvement of the structure degree in the all variants with organic fertilization; the exception is variant with Lupinus angustifolius, green manure; all the other physical properties studied were improved in the all the variant studied: the values of the bulk density and penetration rezistance decreased and total porosity and hydraulic conductivity incresead. The laboratory analysis emphasize the increases of the mineral nitrogen content in all the studied variants. The pH values where a little bigger than the value of the control but the differences are unsignificant statistically; the mobile phosphorus and potassium content of the soil increased but the differences in comparison with the control where unsignificant statistically; only the difference from variant with manure 50 t/hectare are statistically significant.

Keywords: green manure, Lupinus angustifolius, oat, rape, vetch, ryegrass, manure
