The truth lies within this labels information. It will always disclose what percentage of the nitrogen contained therein is slow release. The cheap fertilizers will say 20% or less of the nitrogen is slow release, but the more expensive types will say 50% or more is slow release.
What is slow release fertilizer made of?
Most slow-release fertilizers are derivatives of urea, a straight fertilizer providing nitrogen. Isobutylidenediurea ("IBDU") and urea-formaldehyde slowly convert in the soil to urea, which is rapidly uptaken by plants.
How do you apply slow release nitrogen fertilizer?
Sprinkle slow-release fertilizer around individual perennials. While wearing gardening gloves, layer a few spoonfuls of fertilizing granules in a circle around the roots of your flowers and other perennials. Try not to place any fertilizer directly on top of the plant, as this will damage your perennials over time.
How often should you use slow-release fertilizer?
Soluble fertilizers, for instance, are applied every two weeks during the growing season. Granular fertilizers are generally applied about every six to eight weeks. Slow-release fertilizers work for months, so one application is generally all that is needed for a growing season.
Should slow-release fertilizer be watered?
No, slow release fertilizer does not need water. However, watering regularly will cause coated fertilizer pellets to release their nutrients sooner. By keeping soil moist, you can cause microbial activity to speed up. In turn, this will lead to faster breakdown of coated and organic slow-release fertilizers.

Can you over fertilize with slow release?
Slow-release fertilizers may help regulate the release of nutrients into the soil over time, but it's still possible to add too much if you don't see results as soon as you expect them. All of these activities can cause plants to show signs of over-fertilizing.
How long does it take for slow release nitrogen to work?
Slow-release lawn fertilizer is gradually broken down into available nitrogen by microorganisms and takes three to ten weeks to improve your lawn. Some of them keep working for a couple of months or even a full year after application.
Is Miracle Grow a slow-release fertilizer?

Can slow-release fertilizer burn lawn?
Although fertilizers with slow-release nitrogen are more expensive than quick-release synthetic fertilizers, the benefits include low risk of burning the turf; more even, sustained grass growth (less mowing); and less leaching into ground and surface water.
How do you know if fertilizer is fast release?
Quick-release fertilizer does exactly what it says it will do: quickly releases the nitrogen and other nutrients to the turf. This type of fertilizer is typically more water-soluble, making it dissolve faster in the soil. You should start to see some lawn growth almost immediately with quick-release fertilizer.
Can you over fertilize with slow release?
Slow-release fertilizers may help regulate the release of nutrients into the soil over time, but it's still possible to add too much if you don't see results as soon as you expect them. All of these activities can cause plants to show signs of over-fertilizing.
Is Scotts fertilizer slow release?
Scotts® lawn fertilizers use a mix of fast- and slow-release nitrogen to help your lawn stay consistently green for 6-8 weeks.
What is the difference between slow release and controlled release fertilizer?
Breakdown and release of the N in sulfur coated urea is by both physical and microbial action and the size of coat determines the release rate. In contrast to slow release fertilizers, controlled released fertilizers have a predictable release pattern over time that is commonly temperature based.
Can you use ESN with urea?
On wheat, Michigan studies have shown that ESN top-dressed prior to green up was as effective as urea or UAN. Blending ESN with urea is another option to provide immediate and long term N availability to wheat.
Is ESN as effective as anhydrous ammonia?
Slow release nitrogen fertilizers. MSU field trials indicate that ESN is just as effective and has many benefits compared to anhydrous ammonia, urea and UAN. Efficient nitrogen (N) fertilizer use is increasingly important with rising costs and potential environmental concerns.
What is Slow Release Fertilizer?
In a nutshell, slow release fertilizers are fertilizers that release a small, steady amount of nutrients over a course of time. These can be natural, organic fertilizers that add nutrients to the soil by naturally breaking down and decomposing. Most often, though, when a product is called slow release fertilizer, it is fertilizer coated with plastic resin or sulfur based polymers which slowly break down from water, heat, sunlight and/or soil microbes.
What is the nitrogen ratio of slow release fertilizer?
Slow release fertilizers for turf grasses, for instance, generally have a higher nitrogen ratio, such as 18-6-12.
Why are fertilizers so controversial?
The subject of fertilizers can also be a little controversial, as many gardeners are hesitant to use anything that contains chemicals on their plants, while other gardeners are not concerned by using chemicals in the garden. This is partly why there are so many different fertilizers available to consumers.
Why are there so many different fertilizers?
The main reason, however, is that different plants and different soil types have different nutrient needs. Fertilizers can provide these nutrients immediately or slowly over time.

Why is slow release fertilizer more expensive?
While slow-release fertilizer tends to be more expensive, its longer period of availability means fewer applications will have to be used.
What are some natural fertilizers?
Other types of naturally-derived fertilizers include finished compost, seaweed meal, and certain animal manures. Unfinished compost and mulches can reduce the amount of available soil nitrogen to some extent. Chemical slow-release fertilizers usually contain synthetic preparations of urea, a nitrogen-containing substance produced by many animals.
Why is nitrogen important for plants?
Nitrogen is necessary for sturdy shoots, healthy leaves, and for making chlorophyll. Chlorophyll is the molecule that allows plants to convert energy and gives them their green color. Slow-release fertilizer has certain advantages and disadvantages. One advantage is that nitrogen is released longer, so slow-release fertilizers provide ...
What is the molecule that gives plants their green color?

Why use slow release fertilizer?
The major benefits from using slow release or controlled release fertilizers over readily-soluble ‘straight’ fertilizers in a nutrient management plan include: A high degree of control over release rates, duration and pattern that ultimately delivers better synchronization with plants nitrogen demand.
What is controlled release nitrogen?
Controlled release nitrogen differs fundamentally from SRN in both technology and mode of nitrogen release. CRN particles are completely encapsulated in a organic resin or polymer coatings. These coatings are the secret to delaying the release of nitrogen in a CRN type.
What is the process of absorbing water through a CRN?
The coatings on the CRN particles act as a semi-permeable membrane – a barrier to some molecules, but allowing certain different molecules to pass through. When CRN is applied to an adequately-moist growing medium, there is a one-way passage of water through the coating to the inside of the particle. This phenomenon is called ‘osmosis’. The absorbed water partially dissolves the urea inside the prill to create a highly-concentrated solution. At this point, the CRN diffuses the urea solution out of the particle into the soil medium.
What is the only nitrogen that a turf plant can use?
Ammonium nitrate is the only form of nitrogen that the turf plant can uptake and use. It should be highlighted that the duration of release in a slow-release nitrogen type is controlled by the effectiveness of the microbial organism’s molecular breakdown which is dependent on other environmental factors.
How does stabilized nitrogen work?
In short, stabilized nitrogen extend the amount of time that nitrogen is available for plant uptake. Before plants can take up nitrogen from urea fertilizer, that urea must be converted via two processes, the first of which is called hydrolysis.
How long does SRN last?
SRN duration 12 to 16 weeks. CRN duration 10 to 14 weeks. A high degree of control over release rates, duration and pattern that ultimately delivers better synchronization with plants nitrogen demand. Improved plant growth and health (plants get what they need as they need it)
What is the name of the chemical that creates nitrogen?
Slow Release Nitrogen (SRN) Slow release nitrogen’s most popular form is methylene urea which is created through a manufacturing process where long-chain molecules are created by chemically combining a nitrogen source with an aldehyde.
