Question

Mapping a soil landscape involves sampling the soil in a systematic manner to identify soil boundaries and characteristics. The method of sampling in a series of transects with sampling points concentrated near expected soil boundaries is the most efficient and effective way to achieve this. A grid-like geometric pattern of evenly spaced points might not be effective in capturing variations in the soil landscape, while a computer-calculated pattern of random points might miss important boundaries. Sampling only in four soil pits may lead to missing some important variations in soil characteristics across the landscape. Therefore, choice C is the best option.
