The Formula Explained
The formula used for calculating fertilizer requirements takes into account crop type, area size, and soil type. For example, the fertilizer needed can be calculated as follows:
Fertilizer = Area Size × Crop Factor × Soil FactorGlossary of Terms
- Crop Type: The type of crop being cultivated.
- Area Size: The size of the land area in acres.
- Soil Type: The type of soil, which affects nutrient absorption.
How It Works: A Step-by-Step Example
Example: For a corn crop on a 100-acre field with loamy soil, the recommended fertilizer is calculated using the formula above.
