General Comments 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 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. 105 To convert the recommendation from lbs per acre to lbs per 1,000 square feet, divide by 43.5. 517 When 100 lbs potash per acre is recommended, split into 2 applications. (When soil test potassium is less than 71 lbs potassium per acre) 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) 651 The soil test boron is low, however, this is not a boron sensitive crop, therefore no boron is recommended. (When soil test boron is low) 652 The soil test manganese is low, however, this is not a manganese sensitive crop, therefore no manganese is recommended. (When soil test manganese is low) |
