Re: Letter to the editor: Hog 'factories' helping to empty rural Iowa/KAY

Hog farms in NC largely utilize lagoon and spray-field waste management of manure effluent. This provides anaerobic digestion of the manure solids, and generally irrigation equipment is employed to spray treated effluent on cropland or hayfields.

Comprehensive Waste Utilization Plans are required for the farm to be permitted. Also,, there has to be a certificated " operator im responsible charge" designated for the system. Operators must complete initial training under Cooperative Extension, and have to take recertification training routinely. The state certifies us as system operators in a separate category from muni system operators, but our job is virtually identical.

Many smaller towns in NC also operate their sewage management by lagoons and spray-fields. The size of the system drives how many bedrooms a given town can support on public sewer service. The size of our lagoons and available spray-fields, depending upon crops planted on them, determines our stocking density.

The waste management is, for all intents and purposes, identical.

Re: Letter to the editor: Hog 'factories' helping to empty rural Iowa-FAUST, FAUST, FAUST!!!!!!!!

The heavy fall application would not be allowed in NC, unless you had or established a growing cover crop within 30 days. All of our land applications have to be one actively growing crop, or where a crop will be actively growing within 30 days.

Re: Letter to the editor: Hog 'factories' helping to empty rural Iowa/K-289

In Virginia, a fair amount of fertilizer cost is offset by land application of municipal waste system biosolids. They stink way worse than manure to me, and can bring in scads of flies for the ride.

That activity is protected under interstate commerce clauses of the Constitution.
