Abstract
An evaluation of polyethylene glycol (P.E.G.) 6000 and P.E.G. 20,000 in the osmotic control of soil water matric potential was conducted using the pressure membrane as a standard. Results indicated that there were no statistically significant differences between the three methods at four matric potentials between −0.51 and −15.3 atmospheres. Hence, either P.E.G. 6000 or P.E.G. 20,000 can be used satisfactorily in the osmotic control of soil water matric potential.Keywords
