EFFECTS OF THE AGRICULTURAL TECHNOLOGIES ON THE SOIL ENVIRONMENT WITHIN AN ORGANIC CERTIFIED FARM: RECOMMENDATIONS FOR A REDUCED TILLAGE PUBLISHEDSorin Liviu Ştefănescu, Irina Calciu, Monica Dumitraşcu, Elisabeta Dumitru
Field research has been performed in one of the first organic farm in Romania (S.A. Stepa, Stupina, Constanţa, organic certified since 2000), with the aim of assessing the agricultural practices impact on the soil physical, chemical and biological state. The entire range of usual analyses were conducted for soil samples collected from five different agricultural plots, under different technologicall undertakings. From the physical side, the findings rose the issue of the high risk of farm’s soils macro- and micro-destruction as well the soil profile shallow layers structural instability within the general context of a low organic matter content. The soil environment indicators are still to be improved whether several tillage approaches are to applied. In this view, recomandation are drawn including minimum/reduced tillage practices which can contribute to increase the farming and farm sustainability.
