Crop rotation is not practiced in the district,
at least not for the purpose of conserving or improving
the producing power of the soil. Under the present mwactice
weeds which are difficult to eradicate have gained a stmng
foothold. Some plan of crop rotation, coupled with summer
fallowing, ané the use of good seed is suggested as a means
of eradicating even the more serious weeds. A rotation to
include small grains, tame grasses, including clovers, and
intertilled crops has proved elsewhere its value in main-
taining the productiveness of soils as well as in contmll-
ing to a considerable degree weed growth and crop diseases.
Such a system is most effective where accompanied by the
use of barnyard manure and proper cultivation. Practically
no commercial fertilizers are used in the district.
