The Wijnandsrade experimental farm in Wijnandsrade is making preparations for measurements that will be carried out in the spring on winter grain that has been planted as an erosion buffer. The current erosion regulations state that if soil is turned on ground with a slope of 2% or more, a buffer strip or buffer area must be planted with grass, grass/herbs or alfalfa. The buffer strip must be sown before 1 December.
For some time now, arable farmers who regularly turn the soil have been wondering why these strips cannot be planted with a winter grain, so they submitted a research proposal to the regional programming committee of the Product Board for Arable Farming.
DLV Plant and Applied Plant Research (PPO) are conducting the study on the Wijnandsrade experimental farm. Strips at this location were sown with grass, winter barley and winter wheat at two separate times in the autumn. Some strips were also left uncultivated.
In the spring, the researchers will simulate rainfall to measure the movement of water and soil in part of the trial field. In another part of the trial field, the natural erosion during the growth season will be monitored. Corridors have been dug into every trial area (see images 1 and 2) to enable more accurate measurements. The first results are expected this summer.
