Abstract: | Container mixes consisting of Pinus radiata bark and brown coal or clay loam soil have poor wetting properties when they are dry, because of the shrinkage of all three and the hydrophobic nature of dry pinebark. The wettability of coarse sand, which is independent of its dryness, is quantitatively transferred to container mixes in proportion to the amount used. |
