Change tillage practices
A replicated site comparison study in 1993-1995 on a silty soil in Kedainiai, Lithuania (Slepetiene & Slepetys, 2005) found that soil organic matter content in the topsoil was higher in minimally-tilled soils (1.46 g/kg) compared to shallow (1.04 g/kg) and conventionally tilled soils (0.97g/kg). There were two long-term tillage experiments, one with high application rates of mineral fertilizers (experiment one: N30-45P45K60), and the other with low application rates (experiment two: N60P90K90-120). Both experiments received mineral fertilizers and farmyard manure. There were four replicates and each area was 36 m2. The crops included vetch Vicia sativa-oat Avena sativa rotation and sugar beet Beta vulgaris. Soil sampling was done annually up to 30 cm in depth in 1993-1995. Soil nitrogen and phosphorus were measured.
