Xtension UF

Xtension™ UF is a premium slow release urea-form fertilizer that delivers a steady, balanced and dependable source of nitrogen. When applied to turf, a small amount of nitrogen is immediately released through water solubility and the remaining portion is released gradually by soil microbes.Xtension™ UF provides a long lasting source of nitrogen to increase beneficial soil microbe populations, support root development and maintain healthy turf growth.

Start the growing season out right and continue feeding your turf well as it grows. Whether on a golf course or a well-used sports field, Xtension™ UF is an excellent product from start to finish.

How Does It Work?


With more than 60% of the total
nitrogen as water insoluble nitrogen (WIN), Xtension™ UF is released through a natural breakdown by soil microbes.

Soil microbes slowly convert the ureaform (UF) within Xtension™ UF into urea, which is converted into ammonium and ultimately into nitrate within the soil.

The speed of nitrogen release is dependent on the length of the
ureaform chains, with longer UF chains providing an extended release.
