Explanation
The hygroscopic coefficient refers to the amount of water that oven-dry soil at 105°C can absorb from an atmosphere with 100% relative humidity. This differs from field capacity, which is the water content after excess water has drained, and from permanent wilting point, which is the moisture level where plants cannot recover.
