Approximation Soil Taxonomic System of the region western part of the Buyuk Menderes Basin by using Landsat satellite images in remote sensing technique. The data gathered from field observation about some soil properties and land requirements of different land use types were correlated and as a result of that the boundaries of land use patterns were carried out. Land use patterns were detected according to suitable land use classes for soil mapping units and potential land use map were done. Land use assessment is likely to be the prediction of land potential for productive land use types. This case is great important in guiding decisions on land uses in terms of potential and conserving natural resources for future generations. The main objective of this study was to determine land resources and to assess potential land use in the west part of the Buyuk Menderes Basin of Aegean region. The study area covers about 24.300 km 2 and formed on alluvial material deposited by Buyuk Menders River. Using Landsat 5 TM satellite images, which cover back and foot slope of mountain and alluvial plains of the western part of Menderes Basin, and taking physiographic units of the region as basis, detailed soil series and phases were determined. Soils of the region were classified as Entisol, Inceptisol as 2 orders, 4 suborders, 4 great groups and 6 sub groups, and 10 series. Twenty-five different land utilization types grouped into 4 major land use groups were evaluated for the studied area’s soils. ILSEN computer model was used to determined potential land use groups and suitable classes for agricultural uses. In addition, ArcGIS software was used to generate their maps and database. Suitability map for agricultural uses results showed that, distributions of the best, relatively good, problematic and restricted agricultural lands were 31,68%, 22,63%, 22,16% and 23,53% respectively. Only 31,68% of the study area has the best land for agricultural uses. The main plant growth limitation soil factors are shallow soil depth, high slope, subsurface stoniness, poor drainage, heavy and coarse sub surface soil texture and low water retention capacity.

Application of SS at different doses did not show any disruptive effect on microbial biomass and activity in the soil. In the microbiochemical parameters analyzed in the soils under the two plant covers treated with SS, increases were seen of 29-30% compared with control, and of 28-30% in comparison with chemical fertilizer application. Yield increases secured by chemical fertilizers were statistically significantly higher than those from the SS 1. In maize grain yield, statistically significant increases were shown in comparison with the control of 90% with SS 3 and of 86% with SS 2. Similarly, seed cotton showed a statistically significant increase in yield of 72% with SS 3. Results obtained from the study show that for degraded soils in Mediterranean biodegradability conditions, application of SS at a rate of 30 t ha-1 yr-1 can be used both as a soil improver to maintain the soil and as an organic fertilizer to increase crop yield.

The experiment was conducted in the experimental fields of Ege Agricultural Research Institute during 2011-2012 in Menemen-izmir. Study area is in the Western Anatolia region of Turkey (38°56'87.96¨-38°56'91.02¨N; 27°03' 57.52¨-27°03'58.61¨E). The field study was conducted in 20 parcels in a randomized-block design with four replications and five different applications including control, mineral fertilizer, treated sewage sludge 12.5 t.ha-1; 25.0 t.ha-1; 37.5 t.ha-1 as dry matter. The parcels dimensions were 3 m width and 3 m length. Corn (Zea mays L. var. ZP 737) was the first crop, wheat (Triticum durum L. var. Ege 88) was second crop. Corn and second crop wheat samples were taken at the end of vegetation periods in two years. Increasing TSS applications to soil resulted in significantly increased concentrations of Pb in corn grain. But it was under threshold values. The heavy metal contents of corn seeds were within the normal limits for Cr, Cu, Ni, Pb and Zn while Cd was not present in corn seeds. On the other hand the heavy metal contents of second crop wheat seeds were within the normal limits for Cd, Cr, Cu, Ni and Zn while Pb was not present in wheat seeds. © by PSP.108G167We thank the Scientific and Technical Research Council of Turkey (TUBITAK) for financial support (Project no: 108G167). -

Altı yıl süreli (1989-1994) bu denemede, ayrımlı toprak işleme aletlerinin toprakların bazı fiziksel özellikleri üzerine olan etkilerini saptamak amaçlanmıştır. Ekim makinası ile doğrudan ekimin kontrol olarak alındığı parsellerde, toprakların hacim ağırlık ve porozite değerleri rotovatör uygulanması ile olumlu yönde değişmişlerdir. Toprakların strüktürel özellikleri, toprak işleme malamalarının tarlaya girmesi ile kontrol parselleri olan doğrudan ekim parsellerine göre azalma göstermiştir. Maksimum agregasyon yüzdesi, sıfır işleme olan parsellerde saptanmıştır. Topraktaki bağlanmamış yani strüktürel özellik kazanmamış olan mil+kil yüzdesi de bu parsellerde düşük düzeylerde saptanmıştır.Soils of the experimental farm belonging to the Faculty of Agriculture-Ege University were analyzed for their physical properties after 6 years of different soil tillage and rotation treatments. Treatments included plough, cultivator, rotovatör, tillage combination (dutzi), direct drill machine, strip tillage and rotary-tiller sou tillage techniques were investigated in winter wheat- second crop maize rotation. Direct drill machine has been selected as a control machine. Bulk density values negatively and porosity values positively chanced by rotovatör application. Structural properties of the soils were destroyed compared to that of control by heavy agricultural machines working in the field. Maximum aggregation percentage was determined in no-till plots. Non aggregated silt+clay percentage in these plots also was found to be in low levels

The experiment was conducted in Menemen Plain, in the Western Anatolia Region of Turkey in 2003–2005. Moist TSS was added to the soil at the rates of 0, 30, 60 and 90 Mg ha−1 on May 1, 2003. Peanut (Arachis hypogaea) was planted as the first crop. On the other hand, mixture of green barley (Hordeum vulgare) and common vetch (Vicia sativa L.) was planted as the second crop. During the experiment, soil samples were taken five times. Increasing TSS applications to this soil resulted in significantly increased concentrations of total N, Cu, Pb and Ni, and available P, K, Ca, Fe, Cu, Zn, Mn concentrations in soil. However, concentrations of available Mg and Na, total Fe, Zn, Mn, Cd, Co and Cr in soil did not significantly change. Micronutrients and heavy metals concentrations in soil were found under threshold values in all sampling periods in this study. Available nutrient concentrations in the soil decreased particularly in the last sampling periods because of plant uptake of nutrients from the applied TSS. It is recommended that 90 Mg ha−1 moist TSS can be added once in a 2-year period for improving nutrient concentrations in Typic Xerofluvent soil.

In this research, effects of different levels of dry azolla on the some soil properties and rocket yield were investigated. Different levels of dry azolla (0, 2, 4, 6 ve 8 t/da) were incorporated into 10 cm soil (Typic xerofluvent, loam texture) depth. The experiment was designed according to randomized blocks with three replications. Increasing levels of azolla significantly increased aggregation percentage, structure stability index, porosity, field capacity, wilting point, available water and organic matter, but decreased nonaggregated silt+clay, bulk density, particle density and pH. The highest yields of rocket were obtained by the application of 6 t/da azolla in 1 st and 2 nd and total harvest. It was followed by 8 t/da, 4 t/da, 2 t/da azolla levels and control, respectively.

Seed cotton yield (71.4%), lint yield (67.7%) and cottonseed yield (74.1%) were increased significantly when sludge was applied at a rate of 30 t/ha (TSS3). The effects of TSS applications on seed yield, lint yield and cottonseed yield were listed as TSS3 > TSS2 > CF > TSS1 > C according to the applications. The increasing TSS levels had a positive effect and increased the total N concentration compared to the control. The highest N value was observed in TSS3 plots, while the lowest value was recorded in control (C) plots. The highest P value was found in control (C) at 0.80% and in 10 t/ha (TSS1) at 0.80%, while the lowest value was found in the TSS2 application (0.70%). The K concentration of cottonseed increased with the increasing TSS rates, from 1.56% in control plots to 2.20% in 20 t/ha application (TSS2). Corresponding to the TSS levels, the calcium of plant tissues was determined by a range of 0.12–0.13%. The treatments of TSS and mineral fertilizer had similar effects on the Mg content of cottonseed, which was in the range of 0.38–0.43%. Na content in plant tissue increased with increasing dose of sludge application compared to control soils. Increasing doses of TSS had no significant effect on the concentrations of iron (Fe), copper (Cu), zinc (Zn), manganese (Mn) and boron (B) in cottonseed. The order of the elements with respect to their amounts in cottonseed was as follows: Fe > Zn > Na > B > Mn > Cu. The concentrations of non-essential elements (Ni, Cd, Cr, Pb, Hg and As) in cottonseed were below the permissible limits.

Precision instruments have been used as the limited length of the track restricted the operating speed to less than 4m/s. It is shown that by judiciously controlling the brake pressure and its application time, the skid of the braked wheelset could be achieved. The instrumented bogie is shown to possess excellent potential for being used as an onboard system for monitoring the dynamics of cash trains during brake application without the need for a wayside magnetic encoder system.

Our provisioning and personalisation procedure is compared with recent works and found to be better in terms of generating client's credentials, implementation of WPKI in UICC, personalisation of mobile payment application by the bank and end to end security. Our mobile payment protocol originating from mobile payment application to the bank is also compared with recent works and found to be better in terms of confidentiality, authentication, integrity and nonrepudiation, preventing double spending, over spending and money laundering, and withstands replay, man in the middle (MITM) and impersonation attacks. Proposed protocols are experimentally verified using BAN logic and scyther tool.

The field study was conducted in 20 plots in a randomized block design with four replications and five different applications including control, mineral fertilizer and TSS (12.5; 25.0; 37.5 Mg.ha-1 as dry matter). Corn (Zea mays L. var. ZP 737) was the first crop, wheat (Triticum durum L. var. Ege 88) was the second crop. Soil samples were taken five times in two years. Increasing TSS applications resulted in significantly increased total biomass and grain yield of corn. However, grain yield of second crop wheat did not change significantly. Increasing TSS aplications were significiantly increased total N, available P and K, pH, total salt and organic matter content of sandy clay soil. However, CaCO3 and cation exchange capacity values of soil did not change significantly. Due to decomposition of TSS in the soil, effect of TSS levels on soil properties decreased in the last sampling periods. Thus, it can be recommended that 37.5 Mg.ha-1 TSS as dry matter can be added once in 2 years for improving plant nutrients and soil properties of sandy clay soil.

In this research, effects of different levels of dry azolla on the some soil properties and rocket yield were investigated. Different levels of dry azolla (0, 2, 4, 6 ve 8 t/da) were incorporated into 10 cm soil (Typic xerofluvent, loam texture) depth. The experiment was designed according to randomized blocks with three replications. Increasing levels of azolla significantly increased aggregation percentage, structure stability index, porosity, field capacity, wilting point, available water and organic matter, but decreased nonaggregated silt+clay, bulk density, particle density and pH. The highest yields of rocket were obtained by the application of 6 t/da azolla in 1 st and 2 nd and total harvest. It was followed by 8 t/da, 4 t/da, 2 t/da azolla levels and control, respectively.

Seed cotton yield (71.4%), lint yield (67.7%) and cottonseed yield (74.1%) were increased significantly when sludge was applied at a rate of 30 t/ha (TSS3). The effects of TSS applications on seed yield, lint yield and cottonseed yield were listed as TSS3 > TSS2 > CF > TSS1 > C according to the applications. The increasing TSS levels had a positive effect and increased the total N concentration compared to the control. The highest N value was observed in TSS3 plots, while the lowest value was recorded in control (C) plots. The highest P value was found in control (C) at 0.80% and in 10 t/ha (TSS1) at 0.80%, while the lowest value was found in the TSS2 application (0.70%). The K concentration of cottonseed increased with the increasing TSS rates, from 1.56% in control plots to 2.20% in 20 t/ha application (TSS2). Corresponding to the TSS levels, the calcium of plant tissues was determined by a range of 0.12–0.13%. The treatments of TSS and mineral fertilizer had similar effects on the Mg content of cottonseed, which was in the range of 0.38–0.43%. Na content in plant tissue increased with increasing dose of sludge application compared to control soils. Increasing doses of TSS had no significant effect on the concentrations of iron (Fe), copper (Cu), zinc (Zn), manganese (Mn) and boron (B) in cottonseed. The order of the elements with respect to their amounts in cottonseed was as follows: Fe > Zn > Na > B > Mn > Cu. The concentrations of non-essential elements (Ni, Cd, Cr, Pb, Hg and As) in cottonseed were below the permissible limits.

Precision instruments have been used as the limited length of the track restricted the operating speed to less than 4m/s. It is shown that by judiciously controlling the brake pressure and its application time, the skid of the braked wheelset could be achieved. The instrumented bogie is shown to possess excellent potential for being used as an onboard system for monitoring the dynamics of cash trains during brake application without the need for a wayside magnetic encoder system.

Our provisioning and personalisation procedure is compared with recent works and found to be better in terms of generating client's credentials, implementation of WPKI in UICC, personalisation of mobile payment application by the bank and end to end security. Our mobile payment protocol originating from mobile payment application to the bank is also compared with recent works and found to be better in terms of confidentiality, authentication, integrity and nonrepudiation, preventing double spending, over spending and money laundering, and withstands replay, man in the middle (MITM) and impersonation attacks. Proposed protocols are experimentally verified using BAN logic and scyther tool.

The field study was conducted in 20 plots in a randomized block design with four replications and five different applications including control, mineral fertilizer and TSS (12.5; 25.0; 37.5 Mg.ha-1 as dry matter). Corn (Zea mays L. var. ZP 737) was the first crop, wheat (Triticum durum L. var. Ege 88) was the second crop. Soil samples were taken five times in two years. Increasing TSS applications resulted in significantly increased total biomass and grain yield of corn. However, grain yield of second crop wheat did not change significantly. Increasing TSS aplications were significiantly increased total N, available P and K, pH, total salt and organic matter content of sandy clay soil. However, CaCO3 and cation exchange capacity values of soil did not change significantly. Due to decomposition of TSS in the soil, effect of TSS levels on soil properties decreased in the last sampling periods. Thus, it can be recommended that 37.5 Mg.ha-1 TSS as dry matter can be added once in 2 years for improving plant nutrients and soil properties of sandy clay soil.
