What is a fertilizer with slow release?

Slow release fertilizer is a type of plant fertilizer that gives plant nutrients for a longer period of time compared to rapid fertilizer release. The release rate concerns the availability of nitrogen that plants can use. Fertilizer with slow release contains nitrogen in molds that are not soluble in water and must be divided by soil organisms before they can be selected by plants. As a result, fertilizers with slow release have their own advantages and disadvantages. Fertilizer with slow release can be synthetic chemical preparation or be derived from organic material such as plants or by -products of animals.

Fertilizers usually contain a certain mixture of three elements most important for plant growth, which are nitrogen, potassium and phosphorus. Nitrogen is essential for robust shoots, healthy leaves and chlorophyll. Chlorophyll is a molecule that allows plants to convert energy and give them their green color.

Slow relsnic fertilizer has certain advantages and disadvantages.One of the advantages is that nitrogen is released longer, so fertilizers with slow release provides nutrients for a longer period of time. Although this means that plants will not show a rapid response to fertilizer, it also reduces the chances of burning plants, which is the result of excessive fertilization. Another advantage that can save time and money is that less fertilizers are likely to be lost to rain or watering in a process known as leaching. While the slow -release fertilizer tends to be more expensive, its longer availability means that fewer applications will need to be used.

organic fertilizers with slow release, made of plant and animal material, contain nitrogen and other plant nutrients in different amounts. Ground hooves and corner contain a lot of nitrogen, which is released slowly. Other types of fertilizers naturally derived compost, seaweed and some animal manure. Unfinished compost and mulch canTo some extent reduce the amount of nitrogen available. The fertilizers of chemical slow release usually contain synthetic preparations of urea, a substance containing nitrogen produced by many animals.

The speed at which nitrogen is available from slow -release fertilizer depends on several factors. Since soil organisms need to be effective, it is best applied in spring and summer, when these microorganisms are most active. Healthy soils contain these organisms naturally. Since the requirements for nitrogen soil differ, fertilizer with slow release can be purchased with a different amount of this nutrient. Soil tests can determine the amount of nitrogen required and this number can be compared to the level on many commercially available fertilizers.
