SeaBlend Plus 12-4-5 Promotes Improved Turf Growth

SeaBlend Plus 12-4-5 from Ocean Organics is a next-generation turf nutrition solution engineered for professionals who demand more than just basic feeding. This advanced surfactant-infused fertilizer goes beyond conventional formulations by combining balanced nutrients with a proprietary low-level surfactant to deliver exceptional infiltration, nutrient uptake, and turf response.

This 12-4-5 formulation is especially suited for turf situations where phosphorus is beneficial—such as during establishment, after aerification, or when turf is recovering from stress or environmental injury. While SeaBlend Plus 12-0-12 is ideal for ongoing maintenance in areas with phosphorus restrictions, SeaBlend Plus 12-4-5 supports early growth, root development, and stronger initial vigor, making it the superior option when faster recovery and establishment are priorities.

One of the core advantages of SeaBlend Plus 12-4-5 is its improved wetting efficiency. The inclusion of a low-level surfactant allows water to infiltrate hydrophobic soils more quickly and evenly. This not only ensures more consistent placement of water and dissolved nutrients in the rootzone but also reduces puddling, runoff, and nitrogen losses through volatilization.

Because water infiltrates the soil more effectively, soil volumetric water content improves—a critical factor in plant health, especially in sandy or sandy loam soils. In trials, co-application of this product with urea outperformed urea-only treatments in maintaining better moisture levels across various soil textures.

This product also offers enhanced nutrient retention. The surfactant-infused formula increases the retention of essential nutrients like nitrate nitrogen, ammonium, and potassium in the rootzone. This means longer availability of nutrients for plant uptake and more consistent support for rhizosphere microbial activity.

With better nutrient retention comes greater nitrogen uptake. In multiple soil types, treated plots showed consistently higher nitrogen absorption, with sandy clay loam soils displaying up to 60% more uptake compared to urea alone. This translates to more efficient fertilizer use and stronger plant performance.

A noticeable faster color response is another key benefit. In trials, turf treated with this product developed visual greening by the first week, whereas urea-only applications didn’t show results until week three. This rapid color change confirms superior nutrient availability and plant uptake.
