Soil sampling in a non-uniform field should be by the ____ method.

Random
Grid
Zone
Composite

The correct answer is: Grid

In a non-uniform field, the grid sampling method is particularly effective because it allows for a systematic and structured approach to collecting soil samples. This method involves dividing the field into a grid pattern and taking samples at regular intervals. The key advantage of this approach is that it captures variability within the field more accurately than random or composite methods. By using the grid method, you can identify nutrient deficiencies or excesses in specific areas, which is crucial for precise nutrient management. This detailed information can inform more targeted agronomic practices, such as variable-rate fertilization, leading to improved crop performance and minimized environmental impact. Therefore, the grid method is ideal for non-uniform fields, as it enhances the ability to recognize patterns and variations in soil properties, ensuring that crop advisors can make well-informed management decisions based on the sampling results.
