Effect of organic amendments and subsequent potential water repellent conditions on major nutrient dynamics in soil

Liyanage, T.D.P.; Leelamanie, D.A.L. (University of Ruhuna, 2017-03-01)
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 ...
Effects of moisture content on the hardness level measurements of the soil

Liyanage, T.D.P.; Leelamanie, D.A.L.; Nilupuli, B.P.A.U. (Wayamba University of Sri Lanka, 2018-08-24)

Hardness is an important soil strength indicator which is widely discussed in agriculture and engineering. Increased hardness levels used in constructions might retard root penetration detrimentally affecting crop productivity. ...
Effects of organic and inorganic amendments on salinity levels of Municipal Solid Waste Composts in Sri Lanka

Liyanage, T.D.P.; Jayasinghe, T.; Prasad, E.M.I.; Manujaya, S.K.P.; Leelamanie, D.A.L. (Faculty of Agriculture, University of Ruhuna, Sri Lanka, 2019-02-28)
Effects of organic matter induced hydrophobicity on soil microbial activity as measured by CO2 evolution

Liyanage, T.D.P.; Leelamanie, D.A.L.; Wanniarachchi, S.D. (Faculty of Agriculture, University of Ruhuna, Sri Lanka, 2014-11-27)
Effects of water repellency on soil organic matter decomposition by microbes

Liyanage, T.D.P.; Leelamanie, D.A.L.; Wanniarachchi, S.D. (University of Ruhuna, 2015-03-04)
Existence of water repellency and its relation to structural stability of soils in a tropical Eucalyptus plantation forest

Piyaruwan, HIGS; Leelamanie, D.A.L. (Elsevier, 2020)

Water repellency is a globally well-known phenomenon in soils that is found to have direct or indirect impacts on vast majority of soil characteristics and dynamics. In this study, we aimed to examine the influence of soil ...
Fire effects on persistence of Soil Water Repellency in Eucalyptus grown Soils in Upcountry Sri Lanka

Piyaruwan, HIGS; Leelamanie, D.A.L. (Faculty of Technology, Eastern University of Sri Lanka, 2022-10-06)

Soil Water Repellency (SWR) is a well-known character, which retards spontaneous penetration of water into soil matrix. It can enhance environmental risks on natural habitats and agricultural lands. There are many factors ...
Hydraulics of repellency and wettability of soils

Liyanage, T.D.P.; Leelamanie, D.A.L. (Faculty of Agriculture, University of Ruhuna, Sri Lanka, 2014-05-06)

Prathibha, J.K.P.N.; Samarawickrama, U.I.; Leelamanie, D.A.L. (Faculty of Agriculture, University of Ruhuna., 2020-02-14)

Growing plants under controlled environments able to provide optimum status for their development. Potting media is a key factor which governs the root environment of potted plants. It provides the physical support, ...
Hydrophobic Effects on Water Retention in Potting Media

Prathibha, J.K.P.N.; Samarawickrama, U.I.; Leelamanie, D.A.L. (University of Ruhuna, 2020-03-04)
Influence of Biochar Addition on pH and EC of Municipal Solid Waste Composts

Rupasinghe, I.S.U.; Abeysinghe, A.A.R.W.; Amarasinghe, S.R.; Leelamanie, D.A.L. (University of Ruhuna, 2021)

Application of biochar to agricultural lands as a means of sequestrating carbon, improving nutrient cycling, and soil health has gained interest. Application of biochar is often known to increase soil pH and EC and is ...
Influence of organic manure amendments on water repellency, water entry value, and water retention of soil samples from a tropical Ultisol

Liyanage, T.D.P.; Leelamanie, D.A.L. (Sciendo, 2016-04-25)

Lowered stability of soil aggregates governed by insufficient organic matter levels has become a major concern in Sri Lanka. Although the use of organic manure with water repellent properties lowers the wetting rates and ...
Influence of soil water repellency on initial infiltration rate and unsaturated hydraulic conductivity of an Ultisol under Pinus caribaea

Piyaruwan, HIGS; Leelamanie, D.A.L. (Faculty of Science, University of Kelaniya, Sri Lanka, 2018-10-26)
