Milk vetch
is a leguminous
crop like the hairy vetch. It ixes ni-
trogen from the air and provides 15
kg (33 lb) of nitrogen per 0.1 ha (¼
ac). Its total biomass is about 17
tons (37,500 lb). In Asia it has
been used as a green manure
plant for thousands of years. It
had been composted after having
been mixed with soil. Sowing sea-
son is before September 20-25 in
the southern area and before
mid-September in the central area.
For good germination, milk vetch
should be sown when there is suffi-
cient moisture in the soil. Milk
vetch is vulnerable to cold and it
can freeze to death if the tempera-
ture stays at below -5°C (23
℉
) for a
long time. You can turn the vetch
into the soil after May 25 after
Rye is planted in this orchard. “Experts” say that be-
cause rye has low nitrogen content, when it decom-
poses it will cause nitrogen suck-in by
microorganisms and thereby damage the growth of
fruit trees. However, in the fields, such concern is
dismissed. The orchard produces more every year.
The owner of this farm has done tree-rye symbiosis
cultivation for over 20 years. (Mr. Jaegwan Yu,
Hadong)
Weight of rye on 1 square meter (11 sq. ft.) was 18
kilograms (40 lb).

Rye
is a gramineous crop. It is very tolerant to cold and can survive tem-
peratures below -25°C (-13
℉
) in the central and northern areas. It provides 15
kg (33 lb) of nitrogen per 0.1 ha (¼ ac) with a total biomass of 20 tons
(44,092 lb). It has strong nutrient absorption so is an excellent source of green
manure. It is also helpful in eliminating salt from the soil. It has a vigorous
root growth which greatly improves the physical characteristics of the soil and
helps with soil compaction. Sowing season is between late September and early
October for high lands and between mid-October to late October for other re-
gions and Jeju Island. e crop will sprout in just four days even in soil tem-
peratures of 4~5°C (39.2-41
℉
). Sow about 15 kg (33 lb) per 0.1 ha (¼ acre).
Mixing hairy vetch and rye in a three to one ratio is an excellent method as
that supplements the low nitrogen of the rye. Return them into soil immedi-
ately before the heading stage.
