Manure and the Environment

Agricultural Production Animal Manure Management

Manure and the Environment

Manure contains four primary contaminants that impact water quality: nitrogen, phosphorus, bacteria and other pathogens, and organic matter. Achieving a nutrient balance will reduce potential environmental hazards often associated with animal agriculture. An annual crop nutrient management plan is needed to ensure an adequate supply of nutrients to sustain profitable crop production, and to balance nutrient inputs (including manure) with crop nutrient needs.

Variable Rate Manure Applications Based Upon Management Zones

Variable Rate Manure Applications
There are many challenges associated with variable rate manure applications such as variable nutrient content within the manure source and nutrient availability, application equipment, and prescription methodology. However, in many cases, these challenges are outweighed by environmental and economic benefits from variable rate manure applications.

Antibiotic use on food animals and its effect on antimicrobial resistance spread and human health.

All food animal managers and pet owners have a role to plan in protecting medically important antimicrobial. Follow @i_AMResponsible on Twitter. Developed by: iAMResponsible.
Most people alive today have never known a world without antibiotics. Antibiotics became widely used to treat bacterial infections in the 1930s and ‘40s, and were quickly labeled a “miracle drug”. But, as widespread use of antibiotics evolved, so did the discovery of antibiotic resistant bacteria. And we have now entered an era where antibiotic resistance is considered one of the biggest worldwide public health challenges of our time.

Manure Phosphorus and Water Quality

Chesapeake Bay experiences summer algae bloom connected with excess phosphorus.
Manure produced in animal feeding operations is a source of fertilizer that can be used to reduce our dependency on commercial fertilizers. Manure contains several essential nutrients that crops that crops rely on to grow, most notably nitrogen and phosphorus. Proper management of manure before, during, and after land application helps to slow down the contamination of our streams and reservoirs.

Tips for Winter Manure Application

snow covered manure
One of the key rules of manure management is to pump and spread manure whenever weather and field conditions allow so that you can maintain storage capacity in case of inclement weather. Unfortunately, “perfect manure application weather” is rare and seldom lasts as long as you need it to. So, if you’re heading into winter with a manure storage that hasn’t been pumped down as much as it needs to be, consider these tips when planning for application.
