Question

Quizplus · Accepted Answer

Gravimetric determinations involve weighing a soil sample before and after drying it in an oven to determine the water content. This provides a direct measurement of the water content. Gypsum blocks, neutron scattering, tensiometers, and pressure membranes all indirectly estimate soil water levels.
