Horizon Ag-Products, LP is a science and research-driven producer of innovative plant health solutions. We specialize in naturally-derived plant health products for the global agricultural market. Horizon Ag-Products is not a fertilizer company. We make fertilizer products perform better. Our technologies and finished products are used by fertilizer manufacturers and dealers to provide improved fertilizer performance by increasing nutrient uptake efficiency. Horizon Ag-Products has developed proprietary chemistries for the broad spectrum of fertilizer delivery methods including soil-applied, dry fertilizer impregnation, and foliar applications.


The benefits of Horizon Ag-Products' sustainable technologies are: improved plant health, promoting crops that are better able to withstand abiotic stresses, and ultimately, increased crop yield. Our technologies also support soil health benefits in a global agricultural community where there is pressure to produce more yield with fewer inputs. We provide solutions that promote sustainable agricultural practices.Learn more about why you should choose Horizon Ag-Products.
