This publication provides direction on estimating soil moisture by the "feel and appearance" method; taking a some soil and rolling it up in a ball then squeezing it between your thumb and forefinger to form a ribbon and noting how it appears and feels. Compare what you see with photographs and/or charts to estimate percent water available and the inches depleted below field capacity.
