Land Potential Data Base - CONSTRAINTFREE File

Modeled crop yields (fresh weight grain) for selected crops (spring wheat, grain corn, soybeans, potatoes, phaseolus bean, barley, oats, canola, and sunflower).

This value represents the potential fresh weight grain yield of that crop without taking into consideration such factors as soil suitability, moisture stress or workability parameter. These yield values are indicative of maximum potential yields, and they are used as input to crop growth models (Stewart, 1981).

Provision has been made for the inclusion of results from a forage model, but at the present time, there are no plans to update this file.
