Fine GradeRoots Terra-Sorb is a nontoxic, super-absorbent hydrogel material that absorbs up to 150 times its weight in water and releases water slowly in dry soils. Mix into potting soil or planting soil to significantly increase the soil’s water-holding capacity, allowing more water to remain in the upper soil profile where it is available to roots. Roots Terra-Sorb repeatedly absorbs and releases water into the soil, lasts for several years until it biodegrades, and is made without sodium. Active Ingredient (% by Weight): 93% Potassium Polyacrylamide/Acrylate Copolymer. Inert Ingredient: 7% Water.Directions For Use – Dipping Bare Root Plants: Mix Roots Terra-Sorb Fine with water at a rate of 1 pound per 20 gallons of water. Water absorption will vary with each local tap water, so use more or less water as needed to achieve the desired consistency that allows the maximum amount of gel to adhere to the roots. Stir gently and allow about 15 minutes to gel. Gel will appear as a collection of individual globules. Dip seedling roots into the gel and remove. Then plant immediately. Apply water to the new plants as usual. Tree Seedling Packing, Shipping, or Planting: Mix Roots Terra-Sorb Fine with water at a rate of 1 pound per 20 gallons of water. Let stand about 15 minutes to gel. Add more water or more product to achieve the desired consistency that permits the maximum amount of gel to adhere to the roots. Squirt or dip the roots of the seedlings prior to storage or shipping to prevent dessication. Hydromulching or Hydroseeding: Add Roots Terra-Sorb Fine to the tank mix at a rate of 50 pounds per acre before adding fertilizer. At a normal rate of 3,000 gallons of water per acre, 50 pounds of Roots Terra-Sorb will hold an additional 900 gallons of water in the seed area. Roots Terra-Sorb Fine is to be mixed into soil. It is not designed for surface applications, other than hydroseeding.
