The goal of the studies and research was to test the contribution of organic fertilisers to the dynamic rebalancing process of soil fertility for the conversion to an ecological agriculture system. In order to achieve our goals, we set field trials within which we tested the impact of an organic fertiliser at different rates (manure: 40, 60, and 80 t/ha) on the regime of soil nutrients and on the rebalancing of soil fertility. There is a lot of research going on in the field, but there are no concrete climate and soil conditions to do it; therefore we need to approach this direction too in the Timisoara area. Research results are favourable and they are readily applicable for a proper conversion to ecological agricultural systems.
