Certified Arborist Practice Exam

The characteristic of fertilizers that are released over a long period of time is referred to as slow-release. This type of fertilizer gradually supplies nutrients to plants, which helps to ensure a consistent nutrient supply over an extended period. Slow-release fertilizers can minimize the risk of nutrient leaching and reduce the need for frequent applications, as the nutrients become available to the plants gradually as they need them. This is particularly beneficial in promoting healthy growth and minimizing nutrient waste.

In contrast to slow-release, rapid-absorption, instant-release, and quick-acting options provide nutrients much more quickly, leading to immediate but often short-lived effects. These methods can lead to potential nutrient runoff or leaching, especially in rainy conditions, which is less of a concern with slow-release products.
