Summary

An experiment was started in 1998 in Central Italy to evaluate changes in soil fertility and the risk of N loss in an organic (ORG) and a conventional low input (CONV) cropping system. At the end of a 6-year rotation, ORG caused a higher plant biomass incorporation into the soil and thus a higher soil soluble organic carbon. The N surplus in ORG was 32% higher than in CONV, while no differences were recorded on N content in the top soil, so that ORG implicated a higher N loss from that soil layer. In ORG we recorded a higher phosphatase activity but a lower available soil P (due to application of rock phosphate in sub-alkaline soil) and a lower exchangeable K.
