"The degradation of natural soil fertility is caused by practicing the classic tillage system (ploughingwith the furrow return) and using high doses of chemical fertilizers. It is necessary to adopt soil tillagetechniques that aim to preserve and improve soil fertility without decrease production. In Romania, soybeancrop, could be an economic boost for the agriculture sector because it reduces the costs required for theprocurement of vegetable protein needed for the livestock and food sector, soybeans being a plant that fixesnitrogen from various sources (precipitation, activity of Bradyrhizobium japonicum bacteria, humusmineralization and residual nitrogen). From the research conducted between 2018-2020 at ARDS Turda,regarding the soybean root nodules cultivated in four tillage systems (CS - plough, MC - chisel, MD - disk andNT- direct sowing) with the technology specific to each system, the results indicate that in a conservative systemthe soybeans yield correlates positively with the number and weight of nodules formed. Organo-mineralfertilization (green fertilizer - autumn rape + gulle manure + N40P40) contributes significantly positively to thenumber and the weight of nodules and increases the yield. As an alternative to the CS, soybean can be cultivatedin a minimum tillage system (MC), the yield difference compared to the classical system (plough) beinginsignificant, just 38 kg. The pedo-climatic conditions of the experimental area it is favourable for this crop andfor the fixation of atmospheric nitrogen, without requiring high doses of mineral fertilizers."
