Urea impregnated at this concentration will be effective in inhibiting urease regardless of the rate of urea applied to the soil. In dry bulk blends, the urea should be impregnated prior to the introduction of other fertilizer materials. Equipment Required An accurate scale to weigh materials. Auger and paddle mixers may also be used. Exposed inner surfaces should be clean, dry and rust-free.
Procedure Use with adequate ventilation.
Respiratory protection not required under normal use. Tumble the urea in the spraying equipment allowing adequate time for uniform coverage. When such circumstances are encountered, the addition of small amounts of a drying agent is recommended. Use blended UAN solution soon after mixing. D LV4 are registered trademarks of Riverside-Terra.
