Proper management practices include the following:

  • Testing manure: Conduct a nutrient analysis of the manure to determine its nitrogen, phosphorus, and potassium content. This ensures you apply the correct amount based on crop needs. A study by Sainju et al. (2016) demonstrates that nutrient management improves crop yields.

  • Composting manure: Composting helps reduce pathogens and improves nutrient availability. According to the Natural Resources Conservation Service (NRCS), composted manure can minimize the risk of environmental contamination.

  • Storage: Store manure in a covered, well-ventilated area to prevent nutrient loss. Keep the manure away from water sources to reduce the risk of runoff. The EPA recommends proper storage to limit environmental impact.

Applying manure at the right time involves:

  • Timing of application: Apply manure before planting or during active crop growth to maximize nutrient uptake. Research by the University of Minnesota (2019) indicates that timing improves nutrient utilization by crops.

  • Weather conditions: Avoid applying manure before heavy rainfall to prevent runoff. The USDA advises monitoring weather forecasts for optimal application times.

Monitoring environmental conditions includes:

  • Soil moisture: Only apply manure when soil is not overly saturated. This prevents compaction and runoff. A study by the Soil Science Society of America states that dry conditions enhance manure incorporation.

  • Crop needs: Tailor applications to match the nutrient requirements of specific crops. According to the International Plant Nutrition Institute (2020), this helps achieve optimal fertilization and reduces excess nutrient loss.

These practices collectively contribute to the safe and effective application of manure, promoting agricultural productivity while protecting the environment.
