IRON FERTILIZER FOR LAWN GREENING AND TONING

Abstract

A fertilizer that is suitable for use all year long that is comprised of extruded or agglomerated pellets having fertilizer and iron, and further comprised of gypsum, seaweed, seaweed extract, humic substances, or a combination of same.

Claims

1. A fertilizer that is suitable for use all year comprising: extruded or agglomerated pellets having fertilizer and iron, and further comprising gypsum, seaweed, seaweed extract, humic substances, or a combination thereof; said fertilizer promoting greening of lawn grasses without strongly stimulating leaf growth; said fertilizer toning said lawn grass, making it more resistant to environmental stresses.

2. The fertilizer of claim 1 wherein said seaweed comprises brown seaweed.

3. The fertilizer of claim 1 wherein said seaweed comprises green seaweed.

4. The fertilizer of claim 1 wherein said fertilizer is blended with approximately 0.5% to about 2% slow-release nitrogen.

5. The fertilizer of claim 4 wherein said slow-release nitrogen is from an organic source, inorganic source or a combination.

6. The fertilizer of claim 1 wherein said gypsum is treated with an anionic, water soluble polyacrylamide (WSPAM).

7. The fertilizer of claim 1 wherein said seaweed or humic substances are included in iron gypsum pellets to produce a homogeneous pellet.

8. The fertilizer of claim 1 wherein said seaweed or humic substances are blended into said fertilizer.

9. The fertilizer of claim 1 wherein said seaweed or seaweed extract is added to said fertilizer at approximately 0.25% to about 2% of total product weight.

10. The fertilizer of claim 1 wherein said humic substances are added at approximately 0.25% to about 10% of total product weight.

11. A fertilizer pellet or granule comprising: iron, gypsum and fertilizer.

12. The fertilizer pellet or granule of claim 11 further comprising: seaweed extract.

13. A method of producing a fertilizer containing iron comprising: processing magnetite and gypsum into magnetite particles and gypsum particles for agglomeration; agglomerating said magnetite particles and said gypsum particles with approximately 1% seaweed extract by weight to form agglomerates; drying said agglomerates; screening said agglomerates; spraying said agglomerates with an oil emulsion of WSPAM; drying said agglomerates; bulk blending said agglomerates with polymer coated urea.

14. The method of claim 13 wherein said WSPAM is applied at 1% of total product weight.

15. The method of claim 13 wherein said polymer coated urea is 0.5% by weight.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0017] An iron fertilizer was produced with the following components: [0018] 1. Magnetite and Gypsum were processed into a particulate form for agglomeration. [0019] 2. The Magnetite particles and Gypsum particles were mixed with 1% seaweed extract by weight and agglomerated with a pressure extrusion agglomeration system. [0020] 3. The resulting agglomerates are dried to the desired moisture content. [0021] 4. The agglomerates are then screened to the desired particle size. [0022] 5. Screened agglomerates are sprayed with an oil emulsion of WSPAM, applying 1% WSPAM of total product weight. [0023] 6. The WSPAM is allowed to dry. [0024] 7. The agglomerates are bulk blended with polymer coated urea (PCU) at 0.5% by weight of PCU.
