The following Table summarizes the average weight of typical plant nutrients found in livestock manure produced daily and yearly.

Notes:

  1. Manure fertilizer elements are not completely available to plants
  2. To determine actual phosphorous (P) weight multiply Phosphate value by 0.437 (P=0.437P2O5)
  3. To determine actual potassium weight multiply Potash value by 0.826 (K=0.826K2O)
