- Abstract:
- In organic farming, alternatives to the conventional soil tillage with the deep-inverting moldboard plough are necessary, to save machine costs and support soil ecology. The modified skim plough “Stoppelhobel” can protect the soil by its shallow inverting working method. At the same time perennial weeds can be suppressed by cutting them under the entire surface. Lower working depths allow less energy consumption and higher working speeds. In 2016, an on-farm field trial was carried out on an organically managed farm in the North of Lower Austria. Soil, vegetation and yield characteristics were examined between two reduced soil tillage methods (Var. A: 3x skim plough, Var. B: 2x cultivator / 1x skim plough). After the soil cultivation, spelt was grown on the trial plots. No significant differences were found between the two variants. This shows the advantages of the skim plough since the same results can be achieved with a shallower working depth. The spelt grain yield of 17.2 dt DM ha-1 (Var A) and 18.3 dt TM ha-1 (Var B) was below the yield level of comparable trials from other years, but it must be considered that there were very dry conditions in 2017. The weed density was on a similar level of other comparable studies. The plant-available nutrients in the soil as well as the soil organic matter content were in the middle to well supplied range. Follow-up experiments over several years could provide more information about the impact of cultivation with the skim plough on the development of soil, crops and weeds.
