The EU nitrate directive aims to protect water resources classed as vulnerable with 50mg nitrate/l. One of the measures considered to avoid nitrate leaching the water source is the systematic coverage of soil by a vegetal cover in autumn. This cover will absorb nitrogen from the soil and air and convert it into organic nitrogen compounds. The cover will then release nitrogen to the next crop, hereby improving soil structure and protecting it from erosion. Precision and high work output are requested for a rapid implementation of cover crops during stubble operations minimizing their costs. The combination of the Vicon short disc harrow Compactiller with the a-drill 500 with 500 l hopper capacity has been designed to meet exactly these requirements.
