Soil soluble lawn fertilisers dissolve into the soil over a few days due to soil moisture; it is not meant to be dissolved by you in water prior to application. Some substances, such as iron sulphate for example do require dissolving prior to application.
The benefits of soluble lawn fertiliser are reduced risk of mower pickup when using rotary mowers together with slightly improved movement of the nutrients away from the surface of the soil down to the roots. This may have some influence on deeper rooting as some fertiliser will go where the water is. Just because it is soluble doesn't necessarily mean it's quick release; all of the above Lawnsmith® Fertilisers except for the Winter Green are slow release with anything from 2 to 6 month longevity.

Coated Lawn Fertiliser
The above Lawnsmith® Coated Fertilisers are available in the Lawnsmith Shop and discussed below:
As the name suggests coated turf fertiliser products have a coating around the fertiliser granule or prill. The coating slows the release of the fertiliser nutrients; as the coating breaks down over time usually due to rising temperature the fertiliser is released. Therefore in cold weather when the grass doesn’t want to grow, very little fertiliser is released. On the other hand, as things warm up and the demand for fertiliser from the grass increases, more fertiliser is released.
The coating can be made of a variety of substances, quite commonly sulphur. This benefits the grass to a point as sulphur is a necessary plant nutrient and used to be abundant due to the smoke and acid rain caused by coal burning fires. Sulphur as it breaks down into its sulphate becomes acidic which is also beneficial for fine turf grasses whilst disadvantaging the weeds. However, over use of coated fertilisers can cause problems.
The great benefit of coated lawn fertiliser is that they will not wash away if there is extreme rainfall so are commonly used for the spring feed. The downside is they can be ‘sucked up’ by rotary mowers until they settle well into the turf. Leaving the box off for the first cut after fertilising the lawn is beneficial. Please check that your mower instructions allow this.
