Slow Release Fertiliser

Slow release fertilisers (SRF) have the ability to provide nutrients to the plant when most needed. These fertilisers take care of the changing needs of the plant and support the seasonal growth process. The nitrogen in the slow release fertilisers is either released by hydrolysis or by microbial activity in the soil.

In order to provide increased longevity, slow release fertilisers (SRF) have also been incorporated into the ImpactPlus range. Coated with Asset Gold, these provide natural organic, inorganic and methylene urea nitrogen sources, utilising a range of methylene urea chain lengths, to provide consistent and increased nitrogen release for up to 12 weeks.

The nitrogen in our slow release fertiliser (SRF) products is either released by hydrolysis or by microbial activity in the soil. As a result, there is far less nitrogen leaching into the soil, meaning fewer applications, a major benefit to the greenkeeper or groundsperson, as well as increased environmental benefits.

These different methylene urea chain lengths provide different nitrogen release times to ensure the plant always has the required nitrogen input. The organic and urea portions release first, providing initial green up. Monomethylene urea releases second and methylene diurea third. The final release phase is polymethylene urea. This gives the products a longevity of 8-12 weeks.
