Always supervise sprayer filling. Consider using a closed handling system, in which the fertilizer is transferred directly from the storage container to the applicator equipment through such a device as a hose. Humans and the environment are never inadvertently exposed to the chemical. Use rinsate for mixing subsequent loads. Spill cleanup For dry spills, promptly sweep up and reuse the fertilizer as it was intended.
Dry spills are usually easy to clean up.
If pesticide gets into your dry fertilizer, it is then considered a pesticide and, if spilled, should be recovered and applied to the target crop as it was intended. Recover as much of liquid spills as possible and reuse as they were intended. You may be required to remove some contaminated soil and apply it to your field, if possible. Report smaller quantities of liquid or dry products if they could cause damage because of the nature of the specific compound or spill location. Remove the spilled material and contaminated soil no matter what the quantity, and dispose according to DNR recommendations.
