Paddy-soils in Java, Indonesia, have been intensively fertilized with phosphate for at least three decades through centralized government programs, which provide subsidized intensification packets to farmers. One side effect of these programs has been an excessive accumulation o…

This study is concerned with the adsorptive behaviour of two triazine herbicides on three mineral soils from Benue state, Nigeria: Aquic Ustropept, Rhodic Kanduistalf and Aeric Ochrauqualf. The soils were characterized using physical, chemical and spectrophotometric methods. The…
The dynamic nature of erosion and associated processes and their dependence on climatic, pedological, land cover, land use, and management factors result in spatial and temporal variability. Computing and mapping this variability will produce information which is essential for d…
This study was conducted near Ibadan, Nigeria to determine the extent of soil acidification due to N fertilization and leaching of Ca, Mg and K from the surface layers of an Oxic Paleustalf (Egbeda series). The N sources included two inorganic N fertilizers, urea (UA) and ammoni…
Associations among soil microstructural type and behaviour, soil erodibility, and soil erosion were investigated at seven research sites of the International Board for Soil Research and Management (IBSRAM) Asialand Sloping Lands Network in Southeast Asia (Chiang Mai and Chiang R…
Damar agroforest is an agroforest system in which damar trees (Shorea javanica) are planted as a main species. A study on damar agroforests was conducted in Pesisir areas (Krui), West Lampung, Indonesia, to determine the changes of tree species composition over time, the relatio…
Accurate estimation of saturated hydraulic conductivity (Ks) in soils is essential for various hydrological applications. Ks is difficult to characterize because of its high variability even over short distances, and measurement methods typically require considerable time and re…
Application of animal waste and biosolid to soil is a common practice and often builds soil phosphorus (P) levels in excess of crop needs, which is a concern for the deterioration of surface water quality. Manure amended treatment released more P but rate of release was slower t…
Soil development combined with sediment storage and erosion in small, upland watersheds are key landscape processes for which assumptions are frequently made but rarely verified in landscape evolution studies. However, processes such as these, acting in small, steep catchments, …
Separating the contribution of habitat filtering and dispersal mechanisms in forming species distribution remains a challenge in community ecology. Despite the effect of environmental variables in structuring communities, only restricted numbers of them were considered as a habi…
Drylands make up more than 45% of the Earth’s land surface and are essential to agriculture and understanding global carbon and elemental cycling. This thesis presents an analysis of atmospheric relative humidity (RH) and temperature (T) as they impact soil moisture and water co…
Anadolu ve Mezopotamya yüzyıllar boyunca pek çok medeniyete ev sahipliği yapmıştır. Bu topraklar üzerinde birçok kavim doğmuş, varlığını sürdürmüş ve yok olmuştur. Bu bölgeler çok uluslu bir yapıya sahiptir. Çok uluslu olması, dinin de çok tanrılı olmasına neden olmuştur. Hem An…
This thesis presents results of centrifuge model tests and three-dimensional large deformation finite element (LDFE) analysis on axial pipe-soil sliding behaviour of partially embedded subsea pipelines. 3D re-meshing and interpolation technique with small strain (RITSS) approach…
Cyclic loading, from earthquake, has caused the instability and failure of slopes composed of sensitive clays. During the 1964 9.2 moment magnitude (M) earthquake in Anchorage, Alaska, several slopes comprised of Bootlegger Cove Formation (BCF) clays failed during the strong sei…
The Sacramento-San Joaquin River Delta, referred to as the Delta, is of great significance to California in numerous aspects. As one of the largest estuaries in the western United States, the Delta is vital to California’s water supply system. Essential lifelines such as the tra…
1908 ile 1918 yılları arası II. Meşrutiyet dönemi olarak adlandırılır. 1908 yılında anayasanın yeniden ilanı ve meclisin tekrar açılması, Osmanlı İmparatorluğu'nda özgürlükçü bir havanın esmesine neden oldu. Bu ortamda İstanbul başta olmak üzere imparatorluğun birçok vilayetinde…
Tezin çalıĢma konusunu oluĢturan seramikler ve seramik parçaları, günümüzde Bursa ili Ġznik ilçesinde yer alan ve antik dönemde Nikaia antik kentinin güney sınırını oluĢturan YeniĢehir Kapısı yakınlarındaki „„Kayıp Kule‟‟ den ele geçmiĢtir. Kayıp Kule açması, Kültür ve Turizm Ba…
Forest ecosystems are important reservoirs for long term carbon (C) storage. Forests of the western United States account for 20-40% of total U.S. carbon C sequestration, and nearly half of the total C in these forests is stored in soil. However, many forests in the western U.S …
The National Building Code of Canada recommends that effective stress ground response analysis be performed if a liquefiable stratum is identified within a soil profile. While constitutive models for total stress ground response analysis have been well verified against earthquak…
