ABSTRACT
Mixtures of Osoflaco sand and screened Canadian peat were examined for bulk density, tension-moisture relations, wilting tensions and readily available water. As peat content increased, mixtures became lighter (less dense), held more available water, had a lower zone of saturation and approached wilting tensions more gradually. Tension-moisture curves indicate relatively uniform pore sizes in the sand, but a relatively wide distribution of pore size in the peat.
