Both laboratory analyses and on-farm quick tests of manure nutrient content play an important role in manure management. Laboratory testing is the most reliable method of manure nutrient testing and is valuable for long-term planning and as a check on quick test results.
Nutrient management plans for crops require estimates of plant-available nitrogen (PAN) provided by application of manure or compost. Recent developments have stimulated interest in utilizing manure nitrogen (N) as a resource. These factors include the following:
• Increased cost of N fertilizers
• Increased value of PAN from manure on...
Phosphorus is an essential element for growth and reproduction of plants and animals. Agricultural enterprises often provide supplemental P to enhance plant and animal performance. Supplemental P inputs are provided in the form of fertilizer or manure for crops, and in the form of feed additives for animals.
