Hairy vetch
is a leguminous
crop which ixes nitrogen in air
and provides 20 kg (44 lb) of ni-
trogen per 0.1 ha (¼ ac) with a
total biomass of about 17 tons
(37,500 lb). One of its wonderful
qualities is that it inhibits weeds.
Its sowing season is between early
September and early October (in
southern Korea). It needs to be
sown by early October at the latest.
Use 3-5 kg (7-11 lb) of seeds per
0.1 ha (¼ ac). Sow more if the cli-
mate is bad or if you sow them too
late. In orchards, cut them down
after they have formed seeds; then,
Hairy vetch growing on an orchard. Being legumi-
nous, they provide all the nitrogen needed by the
fruit trees. 
Milk vetches are planted in rice paddies. Being legu-
minous, they can provide the entire nitrogen needed
for growing rice.

If a crop is planted before their withering, put them back into the soil by using
a rotary two weeks prior to planting so that they have time to decompose. If
crops are planted at a later period, then hairy vetch can be left to die and mulch
the ield. ey grow well in sandy soil or loam with good drainage and are weak
to excessive moisture. With a low
carbon-nitrogen (C/N) ratio of
around 10, it breaks down fast.
