Members of the Iowa Commercial Nutrient Applicators Association are hard at work. Each fall, and part of the spring season a small army of tractors pulling tanks pump Iowa’s hog barns to remove the manure. Kevin Westaby was the founding member and first President of the Iowa Commercial Nutrient Applicators Association. He said his company and the applicators all work with the DNR to comply with rules, and each farmers DNR-sanctioned manure management plan.

Westaby and his associates visited a farm in Franklin County with over a million gallons of hog waste to be pumped, and applied to a field around two miles away. Six large tractors were used, each pulling a 9,000 gallon tank. To buy rigs like these today would run around $350,000 each, so it is not a small investment.
