The seeding rate for green manure is 230-260 kg per hectare.
The period from sowing to embedding in the ground is 50-60 days.
All the green mass of lupine after its cultivation, as green manure, is "earned" into the ground. Over time, it rots and turns into an excellent green fertilizer, significantly increasing nitrogen levels in the soil. Of course, plants grown after green manure lupine respond gratefully to such conditions with a noticeable increase in yield. Lupine saturates the soil with nitrogen Lupine has an unusually powerful root system. With its roots, on which "glomeruli" develop, accumulating nitrogen, he, in the literal sense of the word, loosens the soil and literally feeds it with nitrogen.
Lupin neutralizes soil Experienced gardeners and horticulturists consider lupin an ideal green manure for poor soils (sandy and so-called "empty" soils) that have increased acidity. However, lupin itself does not like very acidic soil. But, if the soil has a moderately acidic reaction, using lupin to neutralize it is not very fast, but it is an inexpensive and effective method. The alkaloids contained in the biomass of lupin, after it is mowed and decomposes in the soil, greatly contribute to its neutralization. With prolonged use of lupin as green manure on the same plot, the soil acquires an alkaline reaction.
