Get a sample of the soil and weigh it. 
Then put your sample in an oven at 110 deg C overnight, and weigh it again to get 
the "dry weight".
The water content of your sample is then just the difference (total weight - dry 
weight).
The amount of water in the soil is nromally quoted as a "percentage water 
content" (or percentage moisture content, which is the same thing). It is given 
by

(total weight - dry weight) / total weight x 100%
