The impacts of manure management in dairy production.
B. Young*1, 1West Virginia University, Morgantown, WV.
Manure management on dairy farms is an important aspect of milk production. The lactating dairy cow produces on average 34 kg of milk each day. In doing so, she will also excrete approximately 54.5 kg of manure daily that needs to be collected, stored, and then utilized in an environmental but effective way. Several factors can affect manure management, storage being one of the most crucial. Storage systems can directly influence the value of nutrients within the manure. In addition to having the necessary capacity for storage, farmers need sufficient land base for application of the nutrients, while adhering to environmental regulations. Most states have restrictions on when manure can be spread on cropland based upon weather. If land base is limited, storage volume needs to be increased to collect the manure for a longer length of time. The goal of manure management is to utilize the nutrients from the manure to maximize crop production. Understanding whole farm nutrient cycling and implementing conservative tillage practices can play a large role. These practices are enforced within the Chesapeake Bay watershed to reduce eutrophication, which has changed the operation of many producers. The same issues in the Chesapeake are starting to occur in the Gulf of Mexico. Thus, learning to manage nutrients within the manure can play a vital role in decreasing environmental issues and increasing production within the Mississippi River Watershed.
