This study was conducted to determine spatial variability in available P content of topsoils and subsoils on a 8.5 ha alluvial wheat field. Phosphorus values were more variable in topsoils than in subsoils since the topsoils have been frequently mixed with plowing activities and applied P fertiliser. Contour maps for available P contents further indicated that available P deposited differed in the subsoils.

Bu amaçla farklı her jeolojik ve jeomorfolojik ünite üzerinde 5 adet profil çukurları açılmış ve alınan örneklerde fiziksel, kimyasal ve minerolojik bileşimleri içinde XRD analizleri yapılmıştır. Yapılan analizlere göre, profiller arasında önemli farklılıklar bulunmuştur. DII plato düzlüğü ile alçak seki üzerinde açılan profiller (PI ve PIII) Entisol olup her ikisinde de baskın kil minerali az miktarda illit ve ayrıca kuvars, kalsit, klorit mineralleri yaygındır. DIII ve DIV plato düzlükleri üzerinde bulunan PII ve PV profilleri Inceptisol ordosunda sınıflandırılmalarına karşılık toprak oluşum olayları bakımından önemli farklılıklar bulunmaktadır. Yüksek seki üzerinde açılan PIV profili ise Mollisol olup, diğer profillerden daha ileri bir toprak oluşum sürecine sahip ve kil mineralleri olarak illit, smektit, palygorskit ve kalsit, kuvars, klorit, feldspat minerallerde bulunmaktadır. Ayrıca güney kesimde bulunan topraklar kuzey kesimine göre profil gelişimi bakımından daha ileri seviyede bulunmakta ve bu profillerde toprak oluş olaylarından özellikle rubefaksiyon ve kalsifikasyon olayları belirlenmiştir.

Many conventional soil analytical techniques are used in an attempt to establish the relationship between soil physical and chemical properties and individual soil components, often disregarding their complex, multi-component interactions 2. Standard procedures for measuring soil properties being time-consuming and expensive, much attention is given to possible alternatives such as near infrared reflectance spectroscopy (NIRS). Near infrared reflectance spectroscopy is a non-destructive analytical technique for studying interactions between incident light and a material's surface 3. Near infrared reflectance spectroscopy is a physical non-destructive, rapid, reproducible and low-cost method that characterizes materials according to their reflectance in the wavelength range between 350 and 2500 nm 2,4-7. Infrared spectroscopy in the near and mid-infrared ranges has been found to be useful in providing rapid, cheap and relatively accurate predictions for a number of soil properties 2,4-7 .

The study area is approximately 25 km far from south of AnkaraGölbaşı and its near vicinity. For this aim, 5 profiles located on different geologic and physiographic units were investigated and soil samples taken from each horizons. Physical, chemical and XRD, determined distribution of mineralogical compositions analysis were done for each soil sample. According to analysis results, it was found that there are significantly differences among the profiles. Dominant clay mineral of PI and PIII profiles formed on DII plateau and on low terrace and classified as Entisol is low illite and they have also quartz, calsit, chlorite minerals. In addition, whereas PII and PV profiles formed on DIII and DIV plateaus were classified as I...

After survey and mapping of the area soils, different soil groups were determined and soil properties and problems were defined. The soil requirements of the plants that will be grown in the area were determined and suggestion about land use were made. This study was made according to Soil Taxonomy. While Yapi series was classified as Typic Torriorthent, Huykesen, Yol and Filindir series were classified as Typic Torrifluvent and genesis, properties and problems of these series were discussed.

Six different soil series in different climatic zones were evaluated. The study areas were chosen under three climatic zones that rank from drier to wetter in WA, USA. The soils of the study areas are formed from windblown silty dust known as loess. Walla walla, Endicott and Pataha series formed under low precipitation, have calcic horizons and duripans of which depths are closely related to amount of precipitation. Climate, parent material and topography played had major effect in attaining the soil properties. Sweitberg, Southwick and Vassar soil series formed under high a precipitation. Therefore, these soil series have no calcic ...

Two profiles were defined from hydromorphic soils in Camhbel and airport In Tokat region, and morphological, physical, chemical, redox features, and redox potential of these profiles were determined. Temperature regime of hydromorphic soil in airport was thermic, and moisture regime was aquic, and this soil was classified as typic epiaquent. In the same way, temperature regime of hydromorphic soil in Camlibel was mesic, and moisture regime was aquic, and this soil was classified as mollic endoaquent. In both soils, The important differences were observed in redox potential according to time, profile features, and place. Generally, redox potential increased from top soil to sub soil, from dry season to wet season.

The objectives of this study were to investigate the effects of different soil management systems: orchard (Al), polyculture (A2), monoculture (A3) and native ecosystems (A4) on some soil properties and the concentrations of trace metals (Fe, Cu, Zn, and Mn). The comparisons between management systems showed that organic matter content (OM) was notably higher at Al site (1.84%). On the other hand, cation exchange capacity (CEC), and clay contents were greater at A2 site (35 cmol kg -1 , 56%) while A3 site contained elevated levels of sand (29%) and CaCO 3 (21%) due to variable soil surface erosion at different land use. The trace metal contents (Fe, Cu, Zn and Mn) were higher at Al and A2 sites, but A3 and A4 sites showed a gradual decrease. The higher Fe, Cu, Zn and Mn contents in Al and A2 sites could be attributed t...

In generally, the quality of the irrigation water of the main and some secondary drainage canals were found satisfactory. However, soil characteristics of irrigated areas must be taken into consideration. Waters from the secondary drainage canals at the entrance of TIGEM and between TIGEM and Cayli village can not be used on soils with poor drainage, but they may be used on other soils with special management programs for salinity and alkalinity controls.
