Sainfoin grows on poor soils:
sandy, sandy, shallow underlain by moraine loam, on eroded and
cartilaginous-gravelly soils rich in lime, where other crops do not give
High productivity. The yield of
green mass during the growing season is up to 400-500 kg/ha and 40-70 kg/ha of
hay. Seed productivity – 3-9 kg/ha and more.
According to the content of feed
units and digestible protein, sainfoin is not inferior to alfalfa and superior
to clover. 100 kg contains: Green mass; Feed units – 22 kg; Digestible protein
– 3.1 kg; Carotene – 6.5 g; Hay; Feed units – 54 kg; Digestible protein – 10.1
kg; Carotene – 2.5 g.
Green mass is a good raw material
for making hay, haylage, silage. When feeding green mass, unlike clover and
alfalfa, it does not cause tympanum in animals.
Productive longevity – 3-5 years
Shoots sainfoin can withstand
spring frosts up -7-90S.
It does not need to use mineral
nitrogen. The number of nodules on the roots is greater than on the roots of
alfalfa. In summer drought, sainfoin preserves working nodules when their
activity is suspended on the roots of other leguminous crops.
It has a high ability to absorb
It accumulates up to 70 kg/ha of
organic matter in the form of root residues, with which about 140 kg of
nitrogen, 30 kg of phosphorus and up to 50 kg of potassium enter the soil.
A great precursor to crops.
Pure sainfoin and its mixtures
with cereal grasses improve the soil structure and protect the soil from water
and wind erosion.
Excellent nectariferous plant.
From 1 ha of sainfoin receive up to 90 kg of nectar.
