Gypsum or nylon electrical resistance blocks are most useful in estimating the soil water content if the soil is quite dry.

Question

Quizplus · Accepted Answer

Gypsum or nylon electrical resistance blocks are most useful in dry soils because they rely on the soil's ability to conduct electricity, which is reduced in wet soil. In wet soil, other methods such as tensiometers or capacitance probes are more effective in measuring soil water content.
