Soil Moist polymer granular is a soil amendment designed to reduce plant waterings by 50%**, reduce transplant shock and soil compaction, and will remain effective in the soil for 3-5 years.** It is an inexpensive form of insurance for the plant and is environmentally friendly. Soil Moist saves time, labor and plant loss.

Note: With the exception of hydroseeding applications (using our Hydro and Hydrobond grade polymers), Soil Moist must be incorporated into the soil at the root level of the plant/green good. Do not top dress or place on the surface.
**Results may vary depending on soil conditions such as salts, pH, microorganisms, u-v

Soil Moist Plus is a water storing granular polymer and a 7-7-7, 8-9 month timed release fertilizer.

Soil Moist Fines is a powder form of the polymer that is used for bare root planting applications.

Soil Moist Hydro is a "sugar" grade polymer used for hydroseeding applications to retain moisture.

Soil Moist Seed Coat is a polymer and graphite mixture that is designed to hold moisture for dry grass seeding.

Soil Moist Disks contain water storing polymer and a 10-10-10, 8-9 month timed release fertilizer in an easy to use disk form. Two sizes of the disks are available: one and two inch disks.

Fines for bare root dipping

Mix one pound of SOIL MOIST FINES (powder-type) with 20-40 gallons of water. Let the product stand for at least 15 minutes. Dip the plant/tree immediately before planting. Adjust the slurry to the thickness that best adheres to the roots. When mixing the FINES in water, be sure the polymer is poured in slowly and the water is moving. The longer the gel is allowed to stand, the tackier it will become and the better it will adhere to the roots. One pound will treat approximately 12,000-19,200 seedlings. SOIL MOIST HYDRO (sugar-type 100-700 microns) can be used as a packing medium for transporting bare root stock.

Use two ounces of SOIL MOIST granular per one foot of rootball. Mix one half the amount around the planting hole, mix balance with backfill. Do not amend the top two inches of the backfill with polymer. Water liberally. Rate should be slightly increased to two to three ounces per one foot of rootball in sandy soils. Soil Moist 2" Disks can also be used. For bulk soil mixing use 2 pounds per cubic yard of soil.

Broad Area Treatment

Flower Beds & Gardens

There are two methods to treat broad areas. The most effective method is to sprinkle a small amount (1/2 tsp.) of SOIL MOIST in the plant hole. Water plants liberally to activate the polymer. Another method is to apply up to one pound of SOIL MOIST per 100 square feet of ground area. Spread the polymer and work into the soil at a depth of three to four inches. For bulk soil mixing use 2 pounds per cubic yard of soil.

Use SOIL MOIST at a rate of six pounds per 1000 square feet or 300 pounds per acre if the polymer is worked into the soil at a depth of five to six inches. Use four to five pounds per 1000 square feet or 175 to 225 pounds per acre if the polymer is worked into the soil at a depth of three to four inches. For sandy soils we recommend five pounds per 1000 square feet or 225 pounds per acre at a depth of three to four inches.

Broadcast the polymer with a spreader or drop seeder for even disbursement. Work into the soil, spread seed or lay sod, roll and water liberally. If applying grass seed, you may want to use our SOIL MOIST SEED COAT.

Soil Moist Seed Coat is a polymer graphite compound designed to increase the germination of grass, wildflower and other types of seeds that are spread on the surface of the ground.

The polymer compound retains excess moisture on the seed surface from water and humid air. The moisture softens the seed tissue to increase germination and establishment. The graphite compound retains heat on the surface of the seed to promote a faster germination in less time.

Compared to non-treated grass seed, independent research and testing have shown that Soil Moist Seed Coat increases the speed of germination by over 20%, increases the percentage rate of germination by over 21% while increasing turf establishment by over 24%.

Add three to four pounds of SOIL MOIST HYDRO (sugar-type) per 1000 gallons of liquid in the storage tank. Let the product stand at least 5 minutes before adding fertilizer. Depending upon water retention desired, soil type and salt content of the water, one acre will require nine to fifteen pounds of SOIL MOIST HYDRO.

HYDROBOND™ Hydroseeding

Use Soil Moist HYDROBOND as a tackifier amendment. Hydrobond is a non-toxic linear polymer that can be used with any paper or fiber mulch products. This product binds the hydroseeding media to the soil particles and reduces erosion. It is economical and easy to apply: use three pounds per acre and simply add to the hydroseed tank along with other components such as seed, mulch and fertilizer.
