Solids Separation
Method: Mechanical or physical process to separate solids from liquids in manure. Environmental Impact: Allows for more targeted application of nutrients and easier handling of solids.
Biofiltration
Method: Using living material to filter and break down pollutants from manure. Environmental Impact: Reduces odors, greenhouse gases, and potential water contamination.
Composting
Method: Aerobic, thermophilic process that stabilizes organic waste. Environmental Impact: Reduces pathogens, volume, and greenhouse gas emissions compared to raw manure.
Cover Crops
Method: Planting crops to take up excess nutrients following the main crop harvest. Environmental Impact: Reduces nitrogen leaching and soil erosion, improving water quality.
Effluent Irrigation
Method: Applying processed liquid manure onto fields for crop use. Environmental Impact: Can lead to nutrient overloading and water contamination if not managed correctly.
Anaerobic Digestion
Method: Biological process that decomposes organic waste in the absence of oxygen. Environmental Impact: Reduces greenhouse gas emissions and produces biogas that can be used as renewable energy.
Manure Lagoon
Method: Liquid storage system designed to handle animal waste. Environmental Impact: Potential for ammonia and methane emissions but allows for controlled application of manure to land.
Nutrient Management Planning
Method: A strategic approach to apply nutrients at the right place, time, and rate. Environmental Impact: Minimizes nutrient runoff to water bodies and optimizes crop use of manure nutrients.
