Comparing The Value Of Various Manure Types

Manure is valuable, especially as fertilizer prices continue to increase. But how do various manure types compare when applied at a comparable rate? Table 1 uses average nutrient contents of various livestock types to compare manure N - P₂0₅ - K₂0 values. When applied at a rate that supplies about 130 lbs P₂0₅, they reflect rates that would be typical for application ahead of a corn crop that would meet nutrient management BMP's.

• Assumes spring application incorporated within 1 day
• ¹ nitrogen available in year of application
• ² Application cost of $10/1000 gal or $3/ton (cost increases as distance from storage increases)
• $/lb value N-P-K = 0.50-0.40-0.30

Other Values

Manure also contains micro nutrients which vary with rations, but typically results in less commercial requirements of zinc, manganese and sulphur for livestock farms. Manure is also valuable for the organic material it provides to the soil. Putting an economic value on the organic matter is difficult since its impact is less obvious in the short term. Over the longer term, regular applications of manure, especially solid manure, result in better moisture holding capacity, better nutrient cycling and less vulnerability for crops to suffer from extremes such as excessive moisture and lack of moisture.
