System controlling soluble phosphorus
View Patent ↗A soil amendment or fertilizer composition made from treating chicken litter or similar animal waste, containing excessive amounts of soluble phosphorus and nitrates, with an alkali metal silicate based solution, possibly after mixing with an aqueous alkali earth metal salt solution useful as an activator. The treatment composition and any activator 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 combination composition for adding growth factors to soil, comprising a combination of animal waste containing soluble phosphorus, and a treatment composition comprising aqueous 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, said treatment composition chemically binding said soluble phosphorus into a stable complex, said treatment composition able to bind up to 50% of such soluble phosphorus.
2. A combination composition described in claim 1 , said aqueous alkali metal silicate comprising aqueous sodium silicate at a concentration in the range of between about 19% and 23% by weight.
3. A combination composition described in claim 1 , said aqueous alkali metal silicate comprising aqueous sodium silicate at a concentration of about 21% by weight.
4. A combination composition described in claim 1 , said anionic surfactant comprising ester of organo-phosphoric acid.
5. A combination composition described in claim 4 , said ester of organo-phosphoric acid comprising a concentration of about 1% by weight.
6. A combination composition described in claim 1 , further comprising an activator comprising magnesium sulfate pre-mixed with the animal waste, said treatment composition able to bind up to 86% of said soluble phosphorus.
7. A combination composition described in claim 6 , wherein said magnesium sulfate is at a concentration of between about 1% and 20% by weight of the activator solution.
8. A combination composition described in claim 6 , wherein said magnesium sulfate is at a concentration of between about 5% and 15% by weight.
9. A combination composition described in claim 6 , said animal waste comprising chicken litter, said magnesium sulfate at a concentration of about 10% by weight of the activator solution, said treatment composition comprising aqueous sodium silicate at a concentration of about 21% by weight of the treatment composition, a prop lone glycol at a concentration of about 1% by weight of the treatment composition, and a phosphate ester at a concentration of about 1% by weight of the treatment composition.
10. A method of making a combination composition for adding growth factors to soil, the combination composition comprising a combination of animal waste containing soluble phosphorus, and a treatment composition comprising aqueous sodium silicate at a concentration in the range of between about 1% and 42% by weight of said treatment composition, a 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% b weight of the treatment composition in amounts effective to chemically bind said soluble phosphorus into a stable complex thereby reducing the availability of the soluble phosphorus by up to 50%, said method of making the combination composition comprising the step of dispersing the treatment composition upon the animal waste.
11. A method of making a combination composition described in claim 10 , further comprising the initial step of dispersing upon the animal waste an activator comprising magnesium sulfate, said treatment composition able to bind up to 86% of said soluble phosphorus.
12. A method of making a combination composition described in claim 11 , further comprising the step of mixing said animal waste and said dispersed activator.
13. A method of making a combination composition described in claim 12 , further comprising the step of allowing the activator-animal waste-composition mixture to dry.
14. A method of making a combination composition described in claim 13 , said activator comprising magnesium sulfate at a concentration of about 10% by weight of the activator solution, said treatment composition comprising aqueous sodium silicate at a concentration of about 21.8% by weight of the treatment composition, propylene glycol at a concentration of about 1% by weight of the treatment composition and ester of organo-phosphoric acid at a concentration of about 1% by weight of the treatment composition.
