Abstract:
1. A method of providing water, gas, and nutrients to a plant in soil at a predetermined time release rate, comprising: providing a substrate including a mixture of a cellulosic compound ranging from 1% to 3% by weight having glucose units with a molecular weight ranging between 90,000 and 700,000, represented by the formula R—O—CH2-COOM, where “M” is a metal substituted on the glucose units of the cellulosic compound and “R” is a cellulose chain; a hydrated metallic salt ranging from 0.1% to 0.03% by weight; water ranging from 96.0% to 99.5% by weight; a micro-nutrient selected from a group consisting of zinc and zinc salts, the concentration of zinc ranging from 0.006% to 0.72% by weight of the weight of water being used; at least one plant growth additive selected from a group consisting of plant growth hormones and plant growth regulators ranging from 0.00001% to 0.0003% by weight of the weight of the water being used; at least one preservative selected from the group consisting of sodium benzoate and potassium sorbate, ranging from 0.01% to 0.3% by the weight of the water being used; a surfactant ranging from 0.0025% to 0.006% by weight of the weight of water being used; and an acetic acid compound, the concentration of acetic acid ranging from 0.1% to 0.48% by weight of the weight of water being used; and placing the substrate in the vicinity of the plant roots.
