Lupin is a decorative plant from the legume family, valued not only for its bright and attractive flowers but also for its high effectiveness as a siderate. Thanks to active nitrogen fixation, up to 150 to 200 kg of nitrogen can accumulate on one hectare, which significantly increases soil fertility. In addition to nitrogen, lupin also enriches the soil with potassium and phosphorus, thanks to its deep root system capable of extracting important mineral substances from deep layers.
The «Olovsky Siderate» variety is narrow-leaved (Lupinus angustifolius L.), early-maturing with a vegetation period of 85‑90 days. The plant is low, upright, and indeterminate, with dark green leaves and white flowers with a yellow boat-petal tip. High crude protein content (up to 23% in green mass, 34% in seeds) makes it a valuable source of nutrients for soil and animals.
Lupin possesses a number of siderate functions: it improves the structure of the top soil layer, increasing its permeability and moisture retention; actively fights harmful microorganisms, reducing the risk of plant diseases. When grown for a long time on one plot, lupin contributes to the disappearance of weeds and wireworms, thereby facilitating subsequent sowing operations. Due to its low alkaloid content (up to 0.851%), it is safe for use in agro-landscapes and for feeding animals.
Thus, «Olovsky Siderate» represents a universal plant that simultaneously decorates the field, increases soil fertility, improves its structure and provides protection from pests. This makes it an indispensable element in the sustainable agriculture system.
