Impact of Farm Size on Whole Farm Nutrient Balance (WFNB)


Take Home Message
Both the number of animals and the size of the land base were not observed to influence WFNB. These pork producers have adopted nutrient management strategies that have diminished the importance of size relative to the management of nutrients. These results call into question the value of determining which facilities need a permit based upon size.

Pig Density Impacts on WFNB

Take Home Message
The density of pigs per unit of crop land is of some importance for determining whole farm nutrient balance. Higher densities tend to result in greater imbalances, although the variability observed was only partially explained by pig density. No recommended or threshold value for pig density per crop acre could be identified from the study.
