Narrow Leaf Lupines - Lupinus angustifolius

Narrow Leaf Lupines

Sweet lupines are used as a supplement in poultry, ostrich, dairy, beef, horse, sheep and goat rations. It contains approximately 32% protein and 10% oil and has an energy value of approximately 11 megajoules per kg. Sweet lupines are especially sensitive to high temperatures during flowering and pod formation and are therefore planted during winter. Because legumes such as lupines release nitrogen to the soil, one can expect large yields of crops such as grains if these are planted in soil that was planted to lupines the previous season. Lupine prefers full sun and grows best in sandy soils with a slightly acidic pH.
