| "Phosphorus" is expressed in terms of fertilizer equivalent phosphate as "P2O5", where P x 2.28 = P2O5. | ||||||||||||
| To estimate the equivalent hay or silage yield based on grain yield or to estimate stocking rates (as animal units) based on equivalent hay yield, see Crop File 1.02.022, "Yield Goal Equivalents: Silage, Hay, and Pasture." | ||||||||||||
The value provided as "pounds per yield unit" is either the median value from the Servi-Tech survey or the most common central value obtained from the references. The " ►" symbol indicates there was no common value. The "survey range" represents either the 25th and 75th percentile from the Servi-Tech data or represents the low and high values from the referenced sources.
1 Servi-Tech Laboratories. 2014. In-house data survey of feed analysis results, 2006-2013. Results reported as "Median" or 50th percentile. "Typical range" includes the middle 50% of all samples, so 25% of samples are above range and 25% below. Statistical calculations based on listed number of samples of particular feedsuff that was included in data survey.
