Texas FFA Nursery Landscape Practice Exam

Fertilizers should be added to soil:

1. according to the package instructions and only in the water

2. based on soil test results

3. at 1/2 the rate of fertilizer

4. every year

The correct answer is: based on soil test results

Fertilizers should be added to soil based on soil test results because this approach ensures that you provide the specific nutrients needed by the plants and the soil. Soil tests analyze the nutrient levels, pH, and organic matter in the soil, giving you a clear indication of what is lacking and what may be in excess. This data-driven method allows for precise application of fertilizers, which can lead to improved plant growth, better soil health, and more sustainable practices. Using package instructions or a fixed rate might not address the unique needs of a specific soil type or crops, resulting in either insufficient nutrients or environmental harm from over-fertilization. Adding fertilizers every year without assessing the soil condition can lead to nutrient buildup and potential negative impacts on plant health and the ecosystem. Thus, applying fertilizers based on a thorough understanding of soil conditions is essential for effective and responsible gardening or farming.
