When the ground pH is higher than 7.0 , it is too alkalic .
Onlyapply limewhen a grunge test shew that it is necessary .
After program , the calcined lime should last six years .
Apply elemental sulfur in spring or fall using a spreader . The amount necessary depends on soil pH :
Use an extra 10 pounds * if the soil is clay rather than sandy .
snap off the lime software in half and apply double per year if the charge per unit outmatch 10 pounds * for burned lime , 20 pounds * for hydrated fluxing lime , and 50 pound * for limestone .
Each app of elemental sulfur should not exceed 5 pound * , with a maximum annual rate of 20 pounds * . Retest after six to 12 months to determine if reapplication is necessary .

Otherwise , amend the soil before seeding or sodding . stiff soils require amendment that increase porosity , aeration , and drain , while sandy soils command an increase in water and nutritious memory . To align the grunge pH , employ caustic lime or primary sulfur respectively .
