 Following are some guidelines to help take advantage of the far-reaching benefits of Georgia-Pacific's Bumper Harvest® agricultural gypsum plaster.
Lawn & Garden
In residential and commercial landscaping, and lawn and garden applications, gypsum loosens heavy clay soils, breaks surface crusts, and promotes drainage. As a non-burning soil conditioner, it increases air and water circulation to roots, resulting in hearty growth.
| • | New lawns: Apply 15-20 pounds per 100 square feet in fall. For high clay content, increase to 30-40 pounds. | | • | Established lawns: Broadcast 15-20 pounds per 100 square feet. | | • | Flowers and vegetables: Spade in 25-30 pounds per 100 square feet of bed; mix before adding compost. Apply spring or fall uniformly and soak with water. | | • | Shrubs: Spread 3-4 pounds around each shrub; work in; water. |
Leguminous Crops
Bumper Harvest gypsum can be applied with the seed or as top dressing for certain crops when the plant is in flower.
| • | Legumes in rotation: Apply 200-500 pounds per acre in early spring. | | • | Perennials: Apply 200-500 pounds per acre in early spring; repeat application. | | • | Alfalfa and clover: Apply 2,000 pounds per acre at time of seeding, on new crops. | | • | Hay and grasses: Apply 200-600 pounds per acre at time of seeding new crops; apply an additional 500-1,000 pounds per acre after cropping. | | • | Corn: Apply 500-1,000 pounds per acre during ground preparation or drilled in with corn at planting. | | • | Wheat and other small grains: Apply 300-1,000 pounds per acre drilling in or broadcasting at seeding time or when plants first start. | | • | Peanuts: Apply 250-500 pounds per acre applied at last working of the vines (the larger the growth, the heavier the application). |
Root Crops
| • | Potatoes: Apply 500-1,000 pounds per acre when soil is prepared or by drilling in at planting; broadcast over crop when plants first start. |
Beets, Oats, Peas, Turnips, Squash, etc.
| • | Apply 400 pounds per acre, spreading carefully over ground at planting. |
Mushrooms
For mushroom cultivation, Bumper Harvest gypsum functions in a compost of manure and soil as a non-toxic chemical that speeds decomposition, improves texture and ensures proper pH. Gypsum ensures sure crop yields in a minimum production period.
| • | Add 30-60 pounds per ton of fresh manure at first or second turning. | | • | Scatter gypsum over the top of the pile; turn in during regular turning. | | • | Add sufficient quantities of water; do not extend heating process beyond the time necessary to pasteurize and lower the pH. |
Pond Clearing
Bumper Harvest gypsum is used to help clear muddy ponds, proving highly effective in many cases.
| • | Apply 12 pounds for each 100 cubic feet of water to be treated. | | • | Use this formula for obtaining water volume: Determine average depth (1/3 of depth at deepest point), multiply by area in square feet. |
Secondary Uses
| • | Use in poultry houses to promote cleaner, healthier conditions and prevent the presence of ammonia gas. | | • | Use as a disinfectant. | | • | Sprinkle in litter, dust baths and manure pits to absorb moisture, control odor and improve the fertilizing value of manure. |
