.There are two kinds of limestone: calcic and

liteste e supplies the plant nutrient cal-
and dolomitic limestone supplies both cal-
and magnesium.
owybeans respond better to lime than do most
crops with which they might be rotated.
be most effective, any limestone needed should
applied several months before the soybean crop

most effective method to insure that the soy-

epe choices of herbicides should be based on
ledge of the weeds present and the soil type
organic matter in each field. At the time of

ce of herbicide must be based on the weeds
cipated in that field. This can best be accom-
by making weed maps of each field during
previous season.
cultivation is a good method of weed control;
for cultivation to be effective, there must

soybeans be taller than the weeds for this type
