CASE STUDY: Manure Management Practices on New Jersey Equine Farms

The storage model showed that farms with 6 to 10 horses were more likely to have storage facilities than farms not included in the model. This model had a predictive accuracy of 83.3% and an R2 of 0.35 (P < 0.01). The manure spreading model showed that those who spread manure were also likely to credit manure for its fertilizer value. The spreading model had an overall predictive accuracy of 95.5% and an R2 of 0.795 (P < 0.01). These results indicate that although most equine farms did not pose a direct risk to water quality or to a neighbor, most do not currently use best management practices in managing, spreading, or storing manure.
