Parametric approach to land evaluation for forest plantation: A methodological study using GIS model 

Dengiz, Orhan; Gol, Ceyhun; Sarioglu, Fatma Esra; Edis, Semih (Academic Journals, 2010)
In this study, the land suitability analysis has been carried out to identify suitable areas found in the Yesilirmak Delta and the Central Black Sea Region of Turkey for afforest plantation. Climate, slope, soil, topography ...

The Effect of Bio-solid and Tea Waste Applications on Erosion Ratio Index of Eroded Soils 

Ozdemir, Nutullah; Yakupoglu, Tugrul; Ozturk, Elif; Dengiz, Orhan (Springer-Verlag Berlin, 2010)
The aim of this study was to determine the effects of organic wastes such as bio-solid (BS) and tea waste (TW) on erosion ratio index (ER) of eroded soils in different levels (slight, moderate and severe). Soil samples ...

The effects of bio-solid and tea waste application into different levels of eroded soil on N, P and K concentrations 

Ozdemir, Nutullah; Yakupoglu, Tugrul; Dengiz, Orhan (Springer, 2009)
The main objective of the study was to find out the effects of various organic matter sources such as bio-solid (BS) and tea waste (TW) on macro nutrient content of eroded soils. In order to determine different soil ...

Morphology, Physico-Chemical Properties and Classification of Soils on Terraces of the Tigris River in the South-east Anatolia Region of Turkey 

Dengiz, Orhan (Ankara Univ, Fac Agr, 2010)
Alluvial soils, formed by rivers as accumulated sediment deposited at different times, show large variations in their properties over short distances. The main aims of this study were to determine the morphological and ...

Assessment of nitrate leaching risk in hazelnut areas of the Eastern Black Sea region 

Dengiz, Orhan (Asian Journal of Chemistry, 2008)
Prediction of nitrate leaching from cropland is crucial for preventing the surface or groundwater degradation and the economical balance. Nitrate leaching index model used in this study evaluates both soil hydrological ...

Comparison of traditional and geostatistical methods to estimate soil erodibility factor 

Baskan, Oguz; Dengiz, Orhan (Taylor & Francis Inc, 2008)
Soil erosion is a major environmental problem that threatens the sustainability and productivity of agricultural areas. Assessment and mapping of soil erosion are extremely important in the management and conservation of ...

Soil erosion assessment using geographical information system (GIS) and remote sensing (RS) study from Ankara-Guvenc Basin, Turkey 

Dengiz, Orhan; Yakupoglu, Tugrul; Baskan, Oguz (Triveni Enterprises, 2009)
The objective of this research was to assess vulnerable soil erosion risk with qualitative approach using GIS in Ankara-Guvenc Basin. The study area is located about 44 km north of Ankara and covers 17.5 km(2). The selected ...

Effect of modifying land cover and long-term agricultural practices on the soil characteristics in native forest-land 

Gol, Ceyhun; Dengiz, Orhan (Triveni Enterprises, 2008)
Natural forestland soils in the high land mountain ecosystems on the eastern Black sea region of Turkey are being seriously degraded and destructed due to intensive agricultural practices. In this study, we examined four ...

Characteristics and classification of arid region soils: Salt lake specially protected area (Tuz Golu-Turkey) 

Dengiz, Orhan (Asian Journal of Chemistry, 2007)
Salt lake is a unique ecosystem for both agricultural activities and natural life in Turkey. This study was aimed to determine chemical and physical properties and classifying soils of salt lake (Tuz Golu) specially protected ...

Effects of different topographic positions on soil properties and soil enzymes activities 

Dengiz, Orhan; Kizilkaya, Ridvan; Gol, Ceyhun; Hepsen, Suheda (Asian Journal of Chemistry, 2007)
The main objectives of this study were (i) to determine physical and chemical properties of six different soils (ii) to measure the range and degree of three soil enzyme activities, (iii) to evaluate the influence of soil ...
