General Information

1 Apply dolomitic limestone at the recommended rate.  (When lime is recommended and soil test calcium and/or magnesium is low)

4  Apply 100­-150 lbs magnesium sulfate, or 20-30 lbs magnesium oxide, or 90-140 lbs sulfate-of-potash-magnesium per acre, or a mixed fertilizer to supply 10-15 lbs magnesium per acre.  (When the soil test magnesium is low, and for Soil Codes 1, 2, or 3 when the soil pH is greater than 6.5 or for Soil Code 4 when the soil pH is greater than 7.0 or for Soil Code 6 when the soil pH is greater than 6.0)

5  Apply 100­-150 lbs magnesium sulfate, or 20-30 lbs magnesium oxide, or 90-140 lbs sulfate-of-potash-magnesium per acre, or a mixed fertilizer to supply 10-15 lbs magnesium per acre, or by applying 1,000 lbs dolomitic limestone per acre.  (When the soil test magnesium is low, and for Soil Codes 1, 2, or 3 when the soil pH is between 5.9 and 6.6 or for Soil Code 4 when the soil pH is between 5.9 and 7.1 or for Soil Code 6 when the soil pH is 6.0)

6  Apply 435 lbs gypsum per acre or a calcium-containing fertilizer to supply 100 lbs calcium per acre.  (When the soil test calcium is low, and for Soil Codes 1, 2, or 3 when the soil pH is greater than 6.5 or for Soil Code 4 when the soil pH is greater than 7.0 or for Soil Code 6 when the soil pH is greater than 6.0)

7  Apply 435 lbs gypsum per acre, or a calcium-containing fertilizer to supply 100 lbs calcium per acre, or 500 lbs dolomitic or calcitic limestone per acre.  (When the soil test calcium is low, and for Soil Codes 1, 2, or 3 when the soil pH is between 5.9 and 6.6 or for Soil Code 4 when the soil pH is between 5.9 and 7.1 or for Soil Code 6 when the soil pH is 6.0)

9  Apply 10 lbs sulfur per acre, or sufficient sulfur-containing fertilizer to supply this amount.  (For Soil Codes 1 and 2.  For all agronomic crops except Rice, Sunflowers, tobacco  and peanuts)

650  Level of soil test zinc is potentially toxic at the current soil test pH.  Lime according to recommendations.  If the pH is greater than 6.2, consult your local county Extension office or the Home and Garden Information Center at 1-888-656-9988.  (If soil test zinc is greater than 40 lbs per acre for all crops except peanuts)
