To understanding ### Calculation of Soil Moisture (With Example)

A soil sample taken from a field is placed in the aluminium box, weighed, dried in an oven at 105C (221F) and reweighed. The measurements are as follows: Weight of moist soil plus aluminium box = 159 g . Weight of oven dried soil plus aluminium box = 134 g . Weight of empty aluminium box = 41 g . Calculate the moisture content of the soil.

Bulk density of soil is usually determined from a core sample which is taken by driving a metal corer into the soil at the desired depth and horizon. This gives a soil sample of known total volume. From this sample the wet bulk density and the dry bulk density can be determined. For the dry bulk density, the sample is oven dried and weighed ...
