Effects of land conversion from native shrub to pistachio orchard on soil erodibility in an arid region.

Land-use change through degrading natural vegetation for agricultural production adversely affects many of soil properties particularly organic carbon content of soils. The native shrub land and grassland of Gaziantep-Adiyaman plateau that is an important pistachio growing eco-region have been cleared to convert into pistachio orchard for the last 50 to 60 years. In this study, the effects of conversion of natural vegetation into agricultural uses on soil erodibility have been investigated.

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

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 km2.

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

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 erodibility levels (slightly, moderately and severely), erosion ratio (ER) and soil erodibility factor (K) parameters were used. Soil samples used in this research were taken from bulk surface (0-20 cm depth) located on agricultural lands of Asagi Aksu village that is 20 km far from Samsun province in the north part of Turkey.
