The application of either controlled-release fertilizers or slow-release fertilizers can potentially decrease nutrient losses and fertilizer use by 20 to 30 percent of the recommended rate of a conventional fertilizer while enhancing nutrient-use efficiency. So what is a slow release fertilizer? one-time use during the growing season (spring) - saving time spent on maintenance work, the nutrients (macro- and microelements) contained in the slow-release fertilizer are released into the soil gradually, ensuring their availability throughout the growing season, reduction of nutrient leaching from the soil, safe fertilization of plants of different species growing side by side, same chemical composition of each granule, Better uniformity of seeding of all nutrients. The table below summarizes various slow release synthetic fertilizers and their NPK content. They can be used both for plants grown in the ground in the garden and those grown in containers on balconies or terraces, as well as for potted plants grown indoors. Slow release fertilizer or heavy amounts of manure used on crops that form fruit will maintain vegetative growth and fruit, or vegetable development will occur late in the season. Disadvantages of slow-release fertilizers include their higher price per unit of nitrogen and slower green-up rate. Controlled-release fertilizers are dependent on organic resins and polymer coatings to delay the nutrient release, while slow-release fertilizers are not enclosed in coats to achieve extended nutrient release. Slow Release Fertilizer: The Disadvantages The main disadvantage associated with slow-release fertilizers is they sometimes do not break down as quickly as all-purpose products, which means water runoff may wash them away before all the nutrients have a chance to dissolve into your soil.
