The most critical time for arable crops is just after planting or sowing. Circumstances such as increasingly extreme weather conditions, poor soil life or soil conditions and the excessive use of chemical fertilisers do not facilitate the initial crop growth. Maximum and high-quality yields can only be obtained on soils with a good soil structure and a diverse and active soil life. The diversity and activity of the soil life enable the soil processes to run optimally. Mutual competition between the various organisms slows down the growth of harmful organisms, which reduces the risk of diseases. A good soil quality and a diverse soil life make plant roots develop better and plants grow more robustly.
