*Pounds per two tons hay.  Estimate of above-ground growth only. There will be a nutrient contribution from belowground biomass, but this is more difficult to measure. This is an estimate so can't be used to make a farm-specific nutrient budget; instead, a sample of the farm's hay should be analyzed.
