Introductory Crop Physiology: MATRIC POTENTIAL

MATRIC POTENTIAL

MATRIC POTENTIAL

It is the term used for the surface to which the water molecules are adsorbed. The matric potential is the component of water potential influenced by the presence of a matrix. In plant system, the matric potential is disregarded as it is not significant in osmosis.

Matric potential can be measured for the water molecules adhering on the soil particles and cell wall. It has got a negative value. Therefore,
?_w= ?_s + ?_p
