System controlling soluble phosphorus
View Patent ↗An aqueous alkali earth metal salt solution useful as an activator for mixing thoroughly with chicken litter or similar animal waste containing excessive amounts of soluble phosphorus and nitrates. When used as a prelude to treatment with an alkali metal silicate based solution, the aqueous alkali earth metal salt solution greatly increases the chemical binding of the soluble phosphorus and/or nitrates present in the animal waste or nearby environment such as soil or water.
1. A method of using an activator for a composition comprising sodium silicate at a concentration in the range of between about 1% and 42% by weight of said treatment composition, propylene glycol at a concentration of about 1% by weight of the treatment composition, and a phosphate ester at a concentration in the range of between about 1% and 5% by weight of the treatment composition in amounts effective to chemically bind the soluble phosphorus of animal waste into a stable complex thereby reducing the availability of the soluble phosphorus by up to 86%, said activator comprising magnesium sulfate, said method of use comprising the initial step of dispersing the activator upon the animal waste.
2. A method described in claim 1 , further comprising the step of mixing said animal waste and said dispersed activator.
3. A method described in claim 2 , further comprising the step of dispersing, upon the activator-animal waste mixture, said treatment composition.
4. A method described in claim 3 , further comprising the step of mixing the activator-animal waste and the treatment composition mixture.
5. A method described in claim 4 , further comprising the step of allowing the activator-animal waste-composition mixture to dry.
6. A method described in claim 1 , wherein said magnesium sulfate is in aqueous solution at a concentration of about 5% by weight of said activator solution.
7. A method described in claim 1 , wherein said magnesium sulfate is in aqueous solution at a concentration of about 10% by weight of said activator solution.
8. A method described in claim 1 , wherein said magnesium sulfate is in aqueous solution at a concentration of between about 1% and 20% by weight of said activator solution, said animal waste comprising chicken litter.
9. A method described in claim 1 , said activator comprising magnesium sulfate in aqueous solution at a concentration in the range of about 5% and 10% by weight of said activator solution, said composition comprising aqueous solution of sodium silicate at a concentration in the range of between about 19% and 23% by weight, propylene glycol at a concentration in the range of between about 1% and 5% by weight and ester of organo-phosphoric acid at a concentration in the range of between about 1% and 5% by weight.
10. An activator described in claim 1 , said activator comprising magnesium sulfate in aqueous solution at a concentration of about 10% by weight of said activator solution, said composition comprising aqueous sodium silicate at a concentration of about 20.8% by weight, propylene glycol at a concentration of about 1% by weight and ester of organo-phosphoric acid at a concentration of about 1%.
