Texas FFA Nursery Landscape Practice Exam

What is a significant advantage of using slow-release fertilizer in container-grown nursery stock?

1. Can easily be leached from the soil if too much is applied

2. Supplies nutrients over a long period of time with one application

3. Can be applied without expensive equipment

4. Can be injected through the irrigation system

The correct answer is: Supplies nutrients over a long period of time with one application

Using slow-release fertilizer offers the significant advantage of supplying nutrients over an extended period with just one application. This type of fertilizer is designed to release nutrients gradually, typically over weeks or months, depending on environmental conditions such as temperature and moisture levels. This sustained release of nutrients ensures that container-grown nursery stock receives a steady supply of essential elements, promoting healthier growth and reducing the need for frequent reapplication. Consequently, this not only simplifies the fertilization process but also helps maintain consistent soil nutrient levels, which can lead to better plant health and development. In contrast, options that mention the potential for leaching or the need for special application methods detract from the primary advantage of slow-release fertilizers, focusing instead on scenarios that could pose challenges or additional costs.
