A total of 271
persons, including 187 livestock producers, attended 12 livestock waste management
workshops in January and February 2003.
The workshops were held in Center, Wishek, Rhame,
According to surveys answered by producer participants, 66 percent of the animal feeding operations (AFOs) represented were in the small AFO size category, 28 percent were medium AFOs, and 6 percent were large AFOs defined as concentrated animal feeding operations or CAFOs by the new U.S. Environmental Protection Agency CAFO rules. Over one-half of the producers are soil testing and crediting manure nutrients to reduce fertilizer use. However, less than 10 percent are testing manure for nutrients and calibrating manure application equipment. Eighty six percent of the workshop participants graded the workshop A or B on a letter grading scale.
The term “comprehensive nutrient management plan” or CNMP has been used to include all the components of structures, operations, and management necessary to make an animal feeding operation environmentally sound. A regional EPA project resulted in a self-help curriculum to encourage livestock producers to assess their own feeding operations. The goal is to encourage voluntary compliance with environmental regulations by producers who will adopt technically sound, economically feasible, site specific CNMPs. Producers can go through the workbook at their own pace to determine how to minimize the impact of their AFO on water quality.
The CNMP self-help
curriculum includes soil and water inventory, feed management, estimating the
production of manure and manure nutrients and sizing manure storages,
estimating outdoor feedlot runoff volumes and sizing storage structures,
sampling soil and manure, planning to utilize manure nutrients for crop
production, animal mortality management, record keeping, and complying with
regulations. The curriculum has been
revised and adapted for
