Ridgetops in the dryland farming region of eastern Washington suffer from low productivity and poor soil quality from years of erosion. Two studies investigated the effectiveness of soil amendments in restoring soil quality. Study 1 treatments were two rates of compost and a control. Study 2 treatments were compost, coal ash, wheat straw, three rates of inorganic N, and a control. A wide array of soil biological, chemical and physical parameters were measured from 1995 to 1997 and yield of… CONTINUE READING
