Liyanage, T.D.P.; Leelamanie, D.A.L. (University of Ruhuna, 2017-03-01)

Effect of Organic Matter Content at Different Stages of Decomposition on Soil Hydrophobicity

Leelamanie, D.A.L. (University of Ruhuna, Matara, Sri Lanka, 2015-03-04)

If a solid is not completely wettable by water, it is considered to be water repellent or hydrophobic. Organic matter in soils is found be highjy related to the soil hydrophobic conditions. Several studies showed that ...

Effects of Heating on Organic Matter Induced Soil Water Repellency

Leelamanie, D.A.L.; Jayasekara, P.K. (Faculty of Agriculture, University of Ruhuna, Sri Lanka, 2013-11-28)

Soil organic matter plays an important role in making a soil wettable or repellent. Water repellency produced by heating of non-repellent organic matter in soil is common on burned forests and watersheds. The objective ...

Effects of Intermixed Water Repellent Materials on Hydrophysical Characteristics in Potting Media.

Wasana, P.G.U.N.; Samarawickrama, U.I.; Leelamanie, D.A.L. (Farabi Publishing House, Istanbul, Turkey, 2021-08-16)

Potting media act as a facilitator to provide nutrients, physical support, and moisture to plants. With the increasing trend of potted plant industry, problems related to potting media such as water losses, rapid ...
