Slow release fertilisers (SRFs) for turf are a special type of fertiliser that releases nutrients gradually over time. T
his ensures a consistent and predictable nutrient release, which is essential for healthy plant growth. Unlike controlled release fertilisers (CRFs), which use a coating technology to release nutrients, SRFs are made up of minerals that take a certain amount of time to become soluble and available to the turf.
Factors Influencing Nutrient Release
The nutrient release of SRFs is influenced by a variety of factors, including temperature, water, soil pH, and microbial activity.
For example, warmer temperatures and higher levels of soil moisture can increase the rate of nutrient release, while cooler temperatures and drier soil conditions can slow it down.
Soil pH can also affect the rate of nutrient release, as certain minerals may dissolve more quickly or slowly depending on the pH of the soil. Additionally, the activity of soil microbes can also impact nutrient availability.
Benefits of Using SRFs
One of the main benefits of using SRFs is that they provide a steady and sustained release of nutrients to plants, to maintain plant health whilst also reducing the risk of nutrient leaching. This is particularly important in areas where rainfall is high, as excess water can quickly wash away nutrients from the soil.
Cost-Effectiveness of SRFs
Another advantage of SRFs is that they are typically more cost-effective than other types of fertilisers. While they may be more expensive initially, their slow release nature means that they do not need to be applied as frequently, which can reduce overall fertilizer costs in the long term.
ICL’s Innovations in SRF Technology
Overall, ICL’s slow release fertilisers offer a high-quality, reliable source of nutrients for plants, delivering consistent performance over time.
With their gradual nutrient release and ability to withstand environmental factors, SRFs are an effective and sustainable option for maintaining healthy plant growth.
