Managing N, P, and K for the Dairy Industry

Powers, Wendy J.
Challenges in meeting environmental objectives continue to dictate that new and innovative strategies be developed, such that economically viable practices are implemented. Nutritional regimens drive the input side of nutrient management. Therefore, adoption of feeding practices that minimize excretion are necessary. Minimizing over-feeding of phosphorus has been demonstrated to reduce P excretion. Similar findings have been observed when protein feeding is tailored to not exceed animal needs. Current regulations enhance the challenge of utilizing co-product feeds while minimizing nutrient excretions. Yet, regulations currently in place in some states, with the opportunity to be adopted in others, require that we address the challenges now and that we not expect a post-excretion solution.
