  1. To be most effective, all recommended limestone and/or fertilizer should be incorporated 6 to 8 inches into the soil prior to planting. If plants or crop is established, apply recommended materials to the surface and water area well.

    Use a high quality agricultural ground limestone product to meet the limestone recommendation on this report. Manufacturers of agricultural ground limestone products provide a number called the calcium carbonate equivalent, or CCE, on the label. CCEs with high numerical values (close to 100 or above) indicate a pure lime source (greater ability to neutralize soil acidity). The amount of lime recommended on this report is based on an agricultural ground limestone with a CCE of 100. If your lime source is close to or equal to 100, you don't need to adjust the recommended amount. In the event that you use a lime source with a CCE well below 100, use the following formula to adjust the required amount.

    Actual liming material required= ((Soil test recommendation in lbs of lime/1000 square feet) x 100) ÷ CCE of liming material

    Example Only:

    Soil Test Recommendation: 5 lbs lime/100 square feet
    CCE on label: 70 percent
    Actual liming material required = ((5 lb of limestone/100 square feet) x 100) ÷ 70 = 7 lbs liming material/100 square feet

  2. If 11 to 20 pounds of limestone are recommended, divide the amount by two and apply in two applications six months apart. If 21 or more pounds are recommended, divide the amount by three and make three applications at six month intervals.

  3. If 3 or more pounds of MgSO4 (Epsom salts) are recommended, divide the amount by two and make separate applications at four month intervals. If an alternative magnesium source is used, apply an amount equal to the equivalent of 10.5% Mg in MgSO4; Only One Application should be needed.

  4. Lime and fertilizer recommended in pounds of material per each 100 square feet of area to be treated. Use the following conversions to convert from pounds per 100 square feet to other units or area sizes: Pounds per 100 sq. ft. x 10 = pounds per 1000 sq. ft. Pounds per 100 sq. ft. x 435 = pounds per acre:

  5. Amount of sulfur needed to lower soil pH to optimum level. (See Laboratory Results on front of report for soil pH)

    Soil pH
    Soil pH
    (lb/100 sq ft)
    8.0 7.5 0.50
    7.0 1.00
    6.5 2.00
    6.0 3.00
    5.5 4.00
    7.5 7.0 0.75
    6.5 1.25
    6.0 2.50
    5.5 3.50
    7.0 6.5 0.75
    6.0 1.25
    5.5 2.50
    6.5 6.0 1.00
    5.5 1.75
    6.0 5.5 1.50

    Apply sulfur at the above rates for a loam soil. On heavier soil (silt loams) use one third more than the amount shown. On lighter soils (sandy loams) use one-half of the amounts shown. If aluminum or ferrous sulfate is used to lower pH, multiply the above amounts by 2.5. Follow the same suggestions as above for soil types. If 4 or more pounds are needed, divide the amount in half and make two applications six months apart.

  6. There is no reliable test for evaluating the amount of nitrogen (N) in soils that is available to crops over the growing season. The N recommended is based on the actual N that needs to be supplied annually to ensure optimum crop growth.
