Biomend DG Black Gypsum
50 pound bag
When establishing a new turf area, apply prior to or directly after seeding, or while hydroseeding. Irrigation of 0.2 to 0.4 inches will help the granules disperse (not required for hydroseeding) and self-incorporate into the soil. High clay soils and/or colder temperatures will require a higher rate and additional time to self-incorporate due to the fine soil particles. Product will disperse throughout hydroseeding slurry. For corrective soil remediation on established turf areas, apply in Spring and Fall. Multiple applications may be necessary depending on cultural situation.
For ornamentals maintenance place product around the base of each plant in Spring and Fall. For small trees and shrubs apply 1 to 2 cups. For larger trees use 1 cup per caliper inch. For establishing ornamentals mix Biomend DG Black Gypsum with the Back Fill (soil) from excavation for the plant. For small trees, up to 3 inches in caliper, use 1 cup per caliper inch of tree. Trees 3 caliper inch or larger use 2 cups per caliper inch. For establishing ornamental container grown stock into your landscape, see the bottom of chart below.
Product improves quality of composting materials. Spread approximately 2 cups over the top of the material in the cart (every 3 cubic foot of material) as it is dumped into the compost pile. Add 2 cups (for every 3 cubic foot) every time compost is turned until the compost is complete.

Directions for Use
Apply only as directed. For use on crops, establishment or maintenance of turf, agricultural, fruits and vegetables, nursery
crops, gardens, landscape trees, shrubs and flowers. This product will not increase soil pH. It may lower or reduce the soil pH of
unproductive, highly alkaline sodium soils.
Applied to saline-sodic soils, the gypsum will loosen the heavy, hard packed soil, allowing water and air to penetrate and move
freely in the soil. Also utilized to repair areas damaged from winter salt and fertilizer.

| Container Rates - Topdressing Established plants |
| Container Size | Approximate Containers / Cu yd | Conversions |
| 4” square | 1,260 | 3 g = 1/2 teaspoon = 1/10 oz. |
| 5” pot | 800 | 5 g = 1 teaspoon = 1/6 oz. |
| 6” pot | 450 | 8 g = 1 1/2 teaspoon = 1/3 oz. |
| 1 gallon container | 300 | 14 g =1 tablespoon = 1/2 oz. |
| 3 gallon container | 80 | 28 g = 2 tablespoon = 1 oz. |
| 5 gallon container | 50 | 42 g = 3 tablespoon = 1 1/2 oz. |
Double rates from chart above when transplanting container stock into soil for establishment. Mix Biomend DG Black Gypsum with
the Back Fill (soil) from excavation for the plant.
For all applications:
Immediately after application, for optimum results and to disperse the granules, apply a minimum of 0.2 to 0.4 inches of water. If a second
watering is needed to complete the dispersion, wait 10 minutes and again apply a minimum of 0.1 inches of water.
Recent research has shown that environmental buffers prevent pollutants from entering our natural water bodies. To help protect
these natural resources, avoid applying product to sidewalks, driveways, roadways, and other impervious surfaces. Sweep any
misplaced granules back onto the area you are treating immediately after application, since storm drains often empty directly to
nearby waterways.
