Using the Nutrient Units (NU) concept helps ensure an 'apples to apples'
comparison between sizes and types of farm units. Land application
requirements for a farm unit, are based on the specific farm unit's
nutrient management plan, not nutrient units. Nutrient units are
not the same as Livestock Units, which are used in calculating Minimum
Distance Separation (MDS) setbacks.
For agricultural operations that generate manure it is necessary to determine the number of Nutrient Units managed on a farm unit. The number of NUs generated on a farm unit by a particular type of farm animal is calculated by dividing the number of farm animals by the number given in the Nutrient Unit Column shown on Table 3.1 Livestock Information: Type, Nutrient Amount, Nutrient Unit and Housing Capacity. If the farm has more than one type of farm animal then it will have to do this calculation for each type of animal separately, then add all the results to give the total NU generated on the farm.
