Agricultural blend and process of forming an agricultural blend
View Patent ↗The present intention relates to an agricultural blend and a method of forming an agricultural blend. The agricultural blend includes a sulfate source and calcium silicate or a by-product of slag, the slag being selected from the group consisting of steel slag, stainless steel slag, alloy steel slag, carbon steel slag, and phosphate slag. The method includes blending a sulfate source and calcium silicate.
1. An agricultural blend, comprising:
synthetic gypsum;
magnesium silicate; and
calcium silicate;
wherein the synthetic gypsum includes ammonium sulfate.
2. The agricultural blend of claim 1 , wherein the synthetic gypsum includes a greater concentration of sulfates than sulfites.
3. The agricultural blend of claim 1 , wherein the synthetic gypsum is a by-product formed by flue gas desulfurization in a coal combustion process.
4. The agricultural blend of claim 1 , wherein the synthetic gypsum is a by-product formed from a coal combustion process.
5. The agricultural blend of claim 1 , wherein the synthetic gypsum is a by-product formed from bottom boiler ash in a coal combustion process.
6. The agricultural blend of claim 1 , wherein the synthetic gypsum is a by-product formed from hydrogen sulfide produced from a pickling liquor.
7. The agricultural blend of claim 1 , wherein the calcium silicate is a by-product from steel slag.
8. The agricultural blend of claim 1 , wherein the calcium silicate is a by-product from alloy steel slag.
9. The agricultural blend of claim 1 , wherein the agricultural blend is pelletized.
10. The agricultural blend of claim 1 , wherein the agricultural blend is agglomerated.
11. The agricultural blend of claim 1 , wherein the agricultural blend includes, by weight, between 75% and 95% being the synthetic gypsum.
12. The agricultural blend of claim 1 , wherein the agricultural blend includes, by weight, between 5% to 25% being the calcium silicate.
13. The agricultural blend of claim 1 , wherein the agricultural blend includes, by weight, between 5% and 6% H 2 O, between 20% and 24% calcium, between 4% and 6% magnesium, and between 17% and 19% sulfur.
14. The agricultural blend of claim 1 , wherein the agricultural blend includes a pH between 7.5 and 8.5.
15. An agricultural blend, comprising:
synthetic gypsum;
magnesium silicate; and
calcium silicate;
wherein the agricultural blend includes, by weight, between 5% and 6% H 2 O, between 20% and 24% calcium, between 4% and 6% magnesium, and between 17% and 19% sulfur.
16. The agricultural blend of claim 15 , wherein the synthetic gypsum is a by-product formed by flue gas desulfurization in a coal combustion process.
17. The agricultural blend of claim 15 , wherein the synthetic gypsum is a by-product formed from a coal combustion process.
18. The agricultural blend of claim 15 , wherein the synthetic gypsum is a by-product formed from bottom boiler ash in a coal combustion process.
19. The agricultural blend of claim 15 , wherein the synthetic gypsum is a by-product formed from hydrogen sulfide produced from a pickling liquor.
20. The agricultural blend of claim 15 , wherein the calcium silicate is a by-product from steel slag or alloy steel slag.
21. The agricultural blend of claim 15 , wherein the agricultural blend is pelletized.
22. The agricultural blend of claim 15 , wherein the agricultural blend is agglomerated.
23. The agricultural blend of claim 15 , wherein the agricultural blend includes a pH between 7.5 and 8.5.
