prodscore: Soil productivity

Description

Soil productivity scores for farms in townships in four counties in the Minneapolis St. Paul metropolitan area, 1981-82. The goal is to see if the productivity score is a good predictor of the assessed value of the farmland. If so, then productivity score could be used to set assesed value for farms enrolled in the ``green acres'' program that requires that urban farmland be taxed at its agricultural value only without regard to development potential.

Arguments
