Martin UMO Fertilizer Opener

The Martin UMO Fertilizer Opener allows producers to position liquid fertilizers (such as 28%, 30% or 32% nitrogen) close to the seed row, with consistent separation to avoid seedling injury. Crops such as no-till corn usually need additional nitrogen (especially in a cool-wet spring) than just a pop-up product in the row, so the Martin UMO opener will help maintain early plant health and yield, until side-dressed applications occur.

The Martin UMO Fertilizer opener mounts securely to the face plate of a planter and allows a producer to position liquids 1, 2 or 3” to the side of the seed row. It can also be set to place liquids ¾” above, even with, or ¾” below the seed. The Martin UMO opener places fertilizer at a consistent depth in the soil, not into trash or on the planter.

The Martin UMO Fertilizer opener comes standard with a hardened fertilizer boot which is spring loaded against the disc to keep the disc free of soil build up.


The Martin UMO Fertilizer Opener installs within the Floating row cleaner frame and features a double tapered bearing hub. The UMO opener operates at a 4 degree angle and also comes equipped with an adjustable furrow control device which controls soil movement and eliminates soil bubbling.
