Predictive Models

Fertilizer technology has improved just like everything else around us. Today many of the fertilizer producers have spent a tremendous amount of time and money developing highly predicable fertilizer products. Previously slow release products relied on sulfur coatings that were applied around the fertilizer particle to control the release. These products were touted as having a controlled releases of anywhere between 8 and 12 weeks. Unfortunately this was not always what happened in the field due to failures in the coatings.

Now days the coatings that are applied to the fertilizer are made from hi-tech polymers that are not subject to the same failures as previous coatings. These newer coatings will now allow release times of up to 12 to 16 weeks of nutrient supply. This has now allowed for more predicable releases of fertilizer products that help Golf Course Superintendent’s better manage their fertility.

Several of the fertilizer producers now make available software that can be used to show the projected releases of the individual products. This has been extremely useful in allowing the end user to better schedule fertilizer application timings, so that excessive growth is not produced.
