Slow Release Or Control Release Fertilizer
Understanding Slow-Release Fertilizers
Slow-release fertilizers are the total opposite of quick-release fertilizers, in that these types of fertilizers release their components very slowly, which means that plants can get the full benefits from this kind of fertilizer.
Slow-release fertilizers are broken down over a period of time with heat and moisture, unlike quick release fertilizers. Slow-release fertilizers are considered to be safe because of their slow-release, they will not burn plants.
Plants like potted plants that are grown in nurseries, hanging baskets, and interior plantscape benefit greatly from this type of fertilizer.
Many years ago I was employed as an interior plantscape technician, one of my job responsibilities along with my colleagues was to make it a practice to use this type of fertilizer.
The advantages of slow-release fertilizers
- When using these types of fertilizers to fertilize grass there is more uniform growth.
- They are less likely to burn or harm plant life or grass.
- Because of their chemical structure, they are not needed as frequently.
- There may be little chance of leaching(dissolving quickly).
- It can save labor or cut down on labor costs.
The disadvantages of slow-release fertilizer
- They are more expensive than quick-release fertilizers.
- Because of their structure, plant nutrients are not made available right away because as moisture and heat make contact with the soil, they release nutrients over a period of time.
- In cold weather, they will not be as effective in that they need some heat to release nutrients.
