Industrial Lupin is an annual legume plant widely used as a cover crop and protein source for feed. Thanks to its deep taproot system, it can penetrate the soil to a depth of over two meters, allowing it to effectively fix nitrogen and improve fertility even in poor sandy soils.
The crop is highly resistant to diseases and pests, although it can be susceptible to fungal infections such as powdery mildew and fusarium. For successful cultivation, pre-soil treatment, good drainage, and moderate moisture are recommended. Sowing is usually carried out in spring – from April to May, while seed harvesting takes place in July–August.
Industrial Lupin has a number of agronomic advantages: it enriches the soil with nitrogen (can accumulate 150-200 kg per hectare), as well as potassium and phosphorus due to its deep root system. The plant improves the structure of the top layer, increasing its aeration and water absorption capacity. Moreover, lupin performs phytosanitary functions, contributing to the fight against harmful bacteria and improving soil microflora.
For use as a green fertilizer, the plant is usually mowed at the flowering stage, when maximum nitrogen reserves have been accumulated. The green mass is cut and laid in the soil to a depth of about 20 cm, after which it decomposes, enriching the ground.
Industrial Lupin is also valued for the decorative beauty of its flowers and can be used to decorate garden plots. Overall, this crop is a universal tool for increasing the yield of other crops thanks to its cover crop properties and resistance to adverse conditions.
