Despite many sub-varieties within the lupine species, the blue and/or small-leaf lupine (lupinus angustifolius), the white lupine (lupinus albus) and the yellow lupine (lupinus luteus) have the greatest significance in agriculture. In addition, differentiation is made between the sub-varieties "bitter lupines" and "lupines with low bitter substance" (sweet lupines), whereby these differ in the usage and the associated vegetation time. While sweet lupines are often cultivated for fodder usage, the bitter lupine often serves as green fertiliser plant. The most important advantages of the lupine in the green fertiliser usage are the characteristics to convert air nitrogen into plant-available forms with the aid of symbiotic nodule bacteria living on the roots of the plant and thus loosen the soil with roots up to 1.5 m long.
