Animal waste storage and treatment systems have historically been selected and designed to efficiently use valuable fertilizer nutrients for crop production while protecting soil, air and water quality. The primary reason to store manure is to allow the producer to land-apply the manure at a time compatible with the climatic and cropping characteristics of the land receiving the manure.

Manure nutrients can be best utilized when spread near or during the growing season of the crop. Therefore, the type of crop and method of manure application are important considerations in planning manure storage and treatment facilities.

We live in changing times. Farming like your grandparents, your parents or even like your older siblings did may not be possible anymore. Agriculture still has not completely come to grips with the vast changes environmental concerns will thrust on the industry. We can’t even predict which environmental issue will overwhelm us next. There are so many possibilities: sediment, nutrients, biological oxygen demand (BOD), pathogens, antibiotics, hormones, heavy metals and others. Then there are the air issues: ammonia, PM2.5 (particulate matter smaller than 2.5 microns), VOCs (volatile organic compounds) and any kind of odor.
