Abstract

This review addresses issues important to the estimation of wetting, spreading, and adhesion in the development and use of agricultural formulations. Beginning with a thorough review of the physical principles underlying the phenomena, methods for evaluation of the wetting properties of smooth and rugous solids, consolidated and unconsolidated porous media, powders, and fibers are described with some examples of typical data. Only brief mention is made of the importance of dynamics and the measurement of dynamic properties.
