• Pig: 10-15% dry matter requires careful storage
• Texture & Structure:
• Horse manure contains bedding material making it bulky
• Poultry manure is fine-textured requiring covered storage
• Cattle manure forms solid pats needing scraping equipment
• Storage Requirements:
• Fresh manures need 3-4 months aging
• Stack height shouldn’t exceed 6 feet

Planning Your Manure Storage System

A well-designed manure storage system helps maintain nutrient value while protecting water resources and meeting environmental regulations.

Sizing Requirements for Storage Facilities

Your storage facility size depends on livestock numbers farm capacity and storage duration needs. Calculate capacity using these key factors:

• Daily manure production per animal (dairy cow: 150 lbs/day sheep: 4 lbs/day)
• Total number of livestock
• Desired storage period (typically 180-365 days)
• Additional volume for rainwater precipitation
• Safety margin of 10-15% extra capacity

A standard formula: Daily manure × Number of animals × Storage days + Rainfall volume + 15% safety margin = Required storage capacity.

Storage Location and Environmental Factors

Select your storage location based on these critical considerations:

• Minimum 100ft distance from water sources wells & property lines
• Naturally sloped terrain for proper drainage (2-4% grade)
• Easy access for equipment loading & unloading
• Direction of prevailing winds to minimize odor impact
• Soil type & depth to groundwater (minimum 4ft separation)
• Buffer zones with vegetation to reduce runoff
• Year-round accessibility for machinery

Choose elevated areas with good drainage to prevent flooding & groundwater contamination.

Implementing Proper Collection Methods

Efficient manure collection forms the foundation of successful waste management on any farm. The right collection method helps maintain cleanliness while preserving nutrient value.

Mechanical Collection Systems

Automated scraper systems offer efficient manure removal for larger livestock operations. Install conveyor belts or hydraulic scrapers to move waste from barn floors to storage areas throughout the day. Vacuum systems work well for smaller operations handling dry manure while flush systems suit dairy operations. Position mechanical collectors at a 2% slope to ensure proper drainage and prevent liquid pooling.

Manual Collection Best Practices

Start your manual collection routine during cooler morning hours to reduce odor and pest issues. Use moisture-resistant tools like rubber scrapers and non-porous shovels to protect equipment longevity. Clean collection areas daily to prevent waste buildup and maintain a 4-inch bedding depth for optimal absorption. Store tools in a dedicated cleaning station away from feed areas to prevent cross-contamination.

Optimizing Treatment and Processing Techniques

Transform raw manure into valuable agricultural resources through proven treatment methods that maximize nutrient retention and minimize environmental impact.

Composting Methods and Benefits

Implement hot composting by mixing manure with carbon-rich materials like straw hay or wood chips in a 3:1 ratio. Turn piles every 2-3 weeks to maintain temperatures between 131-150°F which kills pathogens and weed seeds. This process creates nutrient-dense compost in 3-4 months while reducing volume by 50%. Benefits include improved soil structure enhanced nutrient availability and elimination of harmful bacteria. Use windrow systems for large volumes or contained bins for smaller operations.

Anaerobic Digestion Systems

Install biodigesters to convert manure into biogas and nutrient-rich digestate under oxygen-free conditions. Small-scale systems can process 100-200 pounds of manure daily producing enough methane to power basic farm operations. Choose between fixed-dome or floating-drum digesters based on climate and budget. Maintain temperatures between 95-105°F for optimal methane production. Monitor pH levels weekly to ensure they stay between 6.8-7.2 for maximum efficiency.

Managing Nutrient Content and Application

Soil Testing and Analysis

Regular soil testing forms the foundation of effective manure application. Send soil samples to a certified lab every 1-2 years to determine pH nutrient levels and organic matter content. Focus testing on fields receiving manure applications targeting areas with different soil types or cropping histories. A comprehensive soil analysis will reveal:

• Nitrogen phosphorus & potassium levels
• Micronutrient concentrations
• pH & organic matter percentage
• Salt accumulation risks
• Heavy metal presence

Timing and Rate of Application

Apply manure during key growth periods when crops need nutrients most. Spring application works best for most annual crops while fall spreading suits winter grains. Calculate application rates using this formula:

Nutrient	Availability First Year	Second Year
Nitrogen	30-50%	10-20%
Phosphorus	60-70%	15-25%
Potassium	80-90%	5-10%

Consider these factors when timing applications:

• Soil moisture conditions
• Weather forecast
• Crop growth stage
• Equipment availability
• Buffer zone requirements
• Seasonal restrictions

Spread manure when soil is dry enough to prevent compaction but moist enough to allow nutrient incorporation. Avoid application before heavy rain to prevent runoff losses.

Preventing Environmental Impact

Runoff Control Measures

Install vegetative buffer strips at least 35 feet wide along waterways to filter manure nutrients before they reach water sources. Create strategically placed diversion berms that redirect surface water away from manure storage areas using a 2% slope gradient. Build sediment basins near high-traffic areas to capture contaminated runoff especially during heavy rainfall events. Consider installing grass waterways in natural drainage paths to slow water movement reduce erosion. Use cover crops like rye or clover during off-seasons to absorb excess nutrients prevent soil erosion.

Groundwater Protection Strategies

Line manure storage facilities with impermeable materials such as clay or synthetic liners to prevent leaching into groundwater systems. Maintain a minimum 100-foot setback distance between manure storage areas wells springs and other water sources. Monitor groundwater quality through quarterly testing of nearby wells for nitrate and bacteria levels. Install observation wells around storage facilities to detect potential contamination early. Use concrete pads under temporary stockpiles to prevent direct soil contact minimize seepage risk.

Following Regulatory Requirements

Compliance with manure management regulations protects water quality and public health while ensuring sustainable agricultural practices.

Federal Guidelines and Compliance

Federal regulations under the Clean Water Act require Concentrated Animal Feeding Operations (CAFOs) to obtain National Pollutant Discharge Elimination System permits. You must maintain detailed records of manure production storage and application practices. The Environmental Protection Agency mandates specific setback distances from water bodies typically 100 feet for surface application and 300 feet for incorporated methods. Additionally comply with nutrient management plans that outline approved spreading rates application timing and soil testing schedules.

State-Specific Regulations

State regulations often impose stricter requirements than federal guidelines for manure management practices. You’ll need to obtain state permits for storage facilities that exceed specific capacity thresholds typically 1 million gallons. Most states require annual reporting of manure handling activities and mandate winter spreading restrictions to prevent runoff during snow melt. Check your state’s agricultural department website for specific requirements including approved storage structure designs minimum setback distances and mandatory operator training programs. Many states also require implementation of comprehensive nutrient management plans reviewed by certified specialists.
