Lupinus annualis is an effective cover crop for reclaiming poor podzolic and sandy soils with high acidity. It rapidly accumulates nitrogen, potassium, and phosphorus in the soil, and is capable of breaking down forms of phosphates inaccessible to other crops, significantly increasing the availability of nutrients for the subsequent crop.
The extensive root system of lupin penetrates deeply into the soil, absorbing macro- and microelements, and promotes the development of beneficial bacteria. Active life of microorganisms in the root zone ensures natural accumulation of nitrogen compounds and processing of atmospheric nitrogen. Thanks to these processes, the plant not only feeds itself but also creates favorable conditions for the next crop.
Lupin is an excellent predecessor for potatoes, tomatoes, peppers, cabbages, and other garden crops. Best sown at the end of July – mid-August after potato or green crop harvest, or earlier in spring on well-moistened soil. After growth, the plant can be dried, crushed, and incorporated into the soil, ensuring a large amount of vegetative mass and improved soil structure. It is important to avoid sowing other legumes after using lupin as a cover crop, as this may disturb the nitrogen balance in the soil.
