How to calculate the moisture content of soil?

To calculate the moisture content of soil, you can use the formula: Moisture Content () ((Wet Weight - Dry Weight) / Dry Weight) x 100. First, weigh a sample of soil when it is wet, then dry it in an oven and weigh it again when it is dry. Subtract the dry weight from the wet weight, divide by the dry weight, and multiply by 100 to get the moisture content percentage.
