Potassium Humate Sulfur Compound Granule
Disclosed is a potassium humate sulfur compound granule and process for making the same granule. The potassium humate sulfur compound granule including a potassium humate component and an elemental sulfur component at a ratio of about 1:20; where the potassium humate component of the granule fully solubilizes upon application to a desired site and enhances conversion of the sulfur component into sulfate by at least about 15% as compared to elemental sulfur alone.
1 . (canceled)
2 . A method comprising:
spray-drying an extracted potassium humate to provide a spray-dried potassium humate powder; and
adding the spray-dried potassium humate powder to elemental sulfur to form a homogenous mixture.
3 . The method of claim 2 , wherein the homogenous powder further comprises a binder.
4 . The method of claim 3 , wherein the binder comprises bentonite clay.
5 . The method of claim 2 , wherein the homogenous mixture comprises a moisture content of about 9 wt. % to about 15 wt. %.
6 . The method of claim 2 , wherein the homogenous mixture exhibits a pH of about 7.5 to about 12.
7 . The method of claim 6 , wherein the homogenous mixture exhibits a pH of about 9.
8 . The method of claim 2 , wherein the spray-dried potassium humate powder and the elemental sulfur are present in a ratio of about 1:20.
9 . The method of claim 2 , further comprising solidifying the homogenous mixture to form potassium humate sulfur granules.
10 . The method of claim 9 , wherein the granules comprise a diameter of about 0.5 to 4.5 mm.
