The SAR is also high,indicating that sodium is a problem. Add gypsum to help reduce sodium. <br /> Divide the gypsum recommendation into three applications where one-third of the recommended rate is applied 4-6 weeks apart when the ground is not frozen. <br /> Add water with the gypsum applications to leach it through the soil to remove sodium from the root zone. <br /> Web site:http://www.soiltestinglab.colostate.edu APPROVED James Self,Ph.D./Extension Soil'hest Specialist <br />
