8 This is a manganese sensitive crop. Apply 10 lbs manganese per acre with the fertilizer when manganese deficiency has been observed in previous years. If manganese deficiency symptoms are confirmed, apply foliar manganese as soon as possible (1 lb manganese per acre) and reapply if symptoms recur.
60 For small grain following legume, reduce the N recommendation by 20 lbs nitrogen per acre. Apply 30-50 lbs nitrogen per acre in the fall and the remaining nitrogen in the spring. The quality of harvested silage will be affected by the stage of growth at harvest, whether in the boot, milk, or dough stage. Percent of dry weight crude protein and in vitro digestibility will decrease with increased maturity, while tons per acre of dry matter will increase. The small grain, whether wheat, oats, or rye, will affect both the yield and quality of silage and its acceptability for livestock type. Seek the advice of an animal specialist.
651 The soil test boron is low, however, this is not a boron sensitive crop, therefore no boron is recommended. (When soil test boron is low)
653 The soil test zinc is low, however, this is not a zinc sensitive crop, therefore no zinc is recommended. (When soil test zinc is low)
