Abstract

A moisturizing gel comprising an aqueous mixture of water and a hydrated metallic salt according to U.S. Patent No. 4,865,640 is improved by the addition of preservative to control water release and optionally the addition of nutrients to feed plants and trees. In the preferred embodiment, a combination of preservatives, one acidic, one basic, is used to provide controllable water release.

Description

Composition and Method for a Moisturizing Agent with Nutrients and/or Preservatives for Controllable Release
Field of the Invention
The present invention relates to a moisturizing agent with micro-nutrients added to feed plants and/or preservatives added that will control the amount of water and fertilizer that will be released over a predetermined length of time. More specifically, the present invention relates to a product and method for providing water and nutrients to plants at a predetermined rate with improved water penetration.
Background of the Invention
The problem of supplying just the right amount of water and nutrients to plants to maintain the desired growth has long been recognized. The commercial product
DRiWATER® gel has been used for several years to provide time release water to plants.
DRiWATER® gel is 97.85% water, 2.00% CMC (carboxymethol cellulose) and .15% Alum (U.S. Patent No. 4,865,640) mixed together to form a gel. The DRiWATER® gel is packaged in cartons, cups, synthetic casings or any other suitable container that can be partially or totally opened for application in the close proximity of the rootball of the plant. The time release feature of the commercially available product results from the action of microorganisms that are exposed to the gel. Previously, feeding had to be done as a separate function, which required application with liquid water as a vehicle to carry the nutrients to the rootball. It would therefore be an advantage to provide DRiWATER® gel with plant nutrients added. It would also be an advantage to further control the liquefaction rate of the DRiWATER® plus nutrients based upon factors other than the degree of exposure to microogranisms. As noted above, the liquefaction rate of DRiWATER® is controlled by the area of product exposed to the soil. The greater surface area exposed to the soil, the faster the DRiWATE®R gel will liquefy.
It would be desirable to further control the liquefaction rate using factors in addition to, or instead of the exposed suface area.
It would also be desirable to facilitate water penetration into the soil.
Summary of the Invention The present invention is the DRiWATER® gel from U.S. Patent No. 4,865,640, with micro-nutrients added to feed plants and/or preservatives added to further control the liquefaction rate to provide an adjustable time release DRiWATER® gel with nutrients added. The present invention waters and feeds plants at a per-determined rate which will provide the desired maintenance for plants. By adding a surfactant to the composition of the present invention, water penetration into the soil can be improved.
Detailed Description
Applicant incorporates the entire specification of U.S. Patent No. 4,865,640 by reference.
The present invention is a moisturizing agent with micro-nutrients and/or food preservatives added. The present invention waters and feeds plants at a pre-determined rate for a pre-determined period of time and facilitates water penetration into the soil, up to 90 days.
The moisturizing agent plus nutrients, plus surfactant composition, according to embodiments of the present invention comprises water, cellulose gum, alum, preservatives, nutrients and surfactant. The water, cellulose gum and alum formula is disclosed in U.S. Patent No. 4,865,640. The preservatives can be selected from sodium benzoate, potassium sorbate, citric acid, sorbic acid, and niposol M sodium, but is not specifically limited to the above. A combination of two preservatives are required, one with basic pH and one with an acid pH to predictably regulate the liquefaction rate. The amount of each preservative can range from 0.01% to 0.04% by weight as a percentage of the weight of the water used. Nutrients can be trace minerals such as iron, zinc, copper, magnesium, cobalt and manganese but not limited to these and nitrogen, phosphoric acids, potassium nitrate, vitamins and combinations of all of the above. Individual or combinations of nutrients can range from 0.007% to 0.01% by weight as a percentage of the weight of the water used. The surfactant can be quixtar's SA 8 water softener, Air Products and Chemicals, Inc.'s Dynol 604, Brewer International's Sil Energy or any other surfactant that will break the surface tension of water. The surfactant can range from 0.0005 to 0.001% by weight as a percentage of the weight of the water used. As an example, the present invention composition according to the preferred embodiment can comprise 887 grams water, 18.14 grams CMC, 1.36 grams alum, 1.8 grams sodium benzoate, 1.8 grams potassium sorbate, 0.7 milligrams nutrients and 0.5 milligrams release agent. This makes one quart of DRiWATER® gel with nutrients and preservatives added.
The preferred embodiment of the present invention comprises a mixture of;
97.797% Water
2.0% Carboxy Methol Cellulose
0.15%) Aluminum Sulfate
5 0.02% Sodium Benzoate
0.02% Potassium Sorbate
0.008%) Phosphoric Acid & Potassium Nitrate
0.001%) Surfactant 0 The DRiWATER® gel with Nutrients and Surfactant is advantageous because it waters and feeds plants on a continual slow release basis and improves water penetration into the soil.
Table one lists examples of the present invention according to different embodiments. 5
