UMAXX®

UMAXX® is a uniquely formulated combination of N-(n-butyl) thiophosphoric triamide, (NBPT): a urease inhibitor and dicyandiamide; a nitrification inhibitor. NBPT stops volatilization for up to two weeks, thus minimizing nitrogen loss and reducing the potential for turf burn. Dicyandiamide blocks the microbial conversion of ammonium nitrogen to nitrate nitrogen. This keeps the nitrogen in the stable ammonium form and in the soil for more efficient plant utilization. It also greatly reduces the leaching of nitrates that can contaminate groundwater. UMAXX® is available in a standard size particle and a mini particle. It is used as a nitrogen component in blended fertilizers and as a soluble nitrogen source for use in liquid applications. UMAXX® is ideal for use on golf courses or wherever quality turf is desired.

UFLEXX® provides protection against nitrogen loss due to volatilization and leaching. UFLEXX® is also used as a nitrogen component in blended fertilizers and as a soluble nitrogen source for use in liquid applications.

Avail®

AVAIL® - New Technology for Improving Phosphate Uptake.

Simplot is proud to introduce “Simplot Stabilized Phosphate” with AVAIL® Technology. Chemical elements in the soil interfere with phosphorus’ ability to be absorbed. By minimizing the adverse effect of these elements on phosphate fertilizer, at the micro-environmental level, AVAIL® increases the potential for more phosphorus to be absorbed by plant root systems. AVAIL® is a non-plant food ingredient designed for coating on granular phosphate fertilizer. It sequesters antagonistic metals in the soil surrounding the fertilizer granules and reduces tie-up of the phosphate. This makes phosphate more available to the plant. AVAIL® is water-soluble, biodegradable and nontoxic. Undisturbed, AVAIL® continues to inhibit phosphate fixation throughout the growing season.

Homogenous Pellet

Non-uniform application of granular dry blend fertilizers can be frustrating, unsightly on turfgrass, and extremely devastating on intensely managed golf course greens and fairways. Granular dry blend fertilizers are mixtures of particles of different sizes, shapes and weights, which often leads to segregation of the elements. Studies have indicated that if the nitrogen is separated from the phosphorus by as much as two inches, there can be as much as a 50% reduction in phosphorus uptake by the plant. The non-uniformity of blends of this type can result in uneven growth, lack of uniform color and increased management problems.

By contrast, reliable NPK delivery, balanced secondary elements and micronutrients, predictable response and consistent results are what you will see every time you apply BEST® fertilizers. Research has shown that the maximum influence of nitrogen occurs when the nitrogen and phosphate are intimately associated together through a process known as positive nutrient interaction. Inside of every BEST® homogeneous pellet, there is a positive interaction between nitrogen, phosphorus and sulfur in increasing the availability and efficiency of each of these important turfgrass nutrients.

6-24-24 XB+
New stronger formulated XB is a dust free, homogeneous pellet now containing a 1-4-4 ratio of nitrogen, phosphorous and potassium. XB+ also has non-staining iron and sulfur. It is an excellent formulation for use as a pre-plant fertilizer for turf and ornamentals.
