_D_e_s_c_r_i_p_t_i_o_n:

     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.
