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.
