“…The soil samples were air-dried in the laboratory and prepared for analyses. They were analyzed for pH, electrical conductivity (EC) (Richards 1954), organic matter (OM) (Nelson & Sommers 1982), calcium carbonate content (CaCO 3 ) (Caglar 1958), and soil texture (clay, silt, and sand content) (Bouyoucos 1951). The amount of aggregates smaller than 0.84 mm was determined by measuring aggregate size distributions of samples with a dry sieving apparatus (Chepil 1952).…”

Başaran M., Uzun O., Kaplan S., Görmez F., Erpul G. (2017): Tillage-induced wind erosion in semi-arid fallow lands of Central Anatolia, Turkey. Soil & Water Res., 12: 144−151.Wind erosion and resultant dust emissions create significant risks for land degradation and ecosystem health in arid and semi-arid regions. In these regions, fallowing constitutes a major component of conventional agriculture. The present study was conducted to determine wind erosion quantities and agricultural activity-induced mass transport from fallow lands and to assess the correlations of mass transport with climate and soil characteristics. Experiments were conducted over the fallow lands of two adjacent agricultural enterprises (Altinova and Gözlü, Turkey). Sediment flux was measured with passive traps in wet and dry seasons (Q tWET and Q tDRY ). Mass transport in wet and dry seasons was respectively measured as 11.38 and 11.40 kg/ha in Altinova and as 31.61 and 19.71 kg/ha in Gözlü. Both the differences between mass transport of the enterprises and the differences between Q tWET and Q tDRY of each enterprise were found to be significant (P < 0.05). Pearson's correlation analysis for the correlations of mass transport with soil characteristics revealed significant correlations with electrical conductivity and soil lime content (r = 0.721 and -0.635) (P < 0.05). Total mass transport from the fallow lands of both enterprises throughout a 7-month period of measurement was estimated at 600 t. Based on current findings it was concluded that fallowing should be abandoned and sustainable soil and land management practices from conventional agriculture like minimum tillage or crop rotations should be introduced.

“…According to the samplings in the application area (Soil Survey Division Staff, 1993), some physical and chemical analyses, macro and micro nutrients of the soils and carbon concentrations of the surface soils were obtained from 60 disturbed soil samples (from 10 (Bouyoucus, 1951). Soil reaction (pH) was measured with pH meter (Richard, 1954) in saturated soil paste; and Electrical Conductivity (EC) was measured using electrical conductivity (Richards, 1954) in saturated soil paste.…”

Abstract. Organic carbon is one of the common indicators used in studies on global climate change for major problems of land degradation, desertification and biodiversity decrease. Carbon as one of the absolute necessary element is indispensable for survival of all living beings. Soils are carbon sources for the land as well as the atmosphere. For that reason, surface carbon amounts and certain parameters were analyzed in this study for the soils in which medicinal and aromatic plants are grown. In this study, physical and chemical analyses were carried out in disturbed soil samples which were taken out at two different depths from totally 60 points in areas with three different medicinal and aromatic plants (Rosmarinus officinalis, Salvia officinalis, Origanum onites) found in Adiyaman-Kahta district. The soils in the study area were determined to have no drainage problem, with clay and clay-loam texture (37.27%), low alkali pH (7.67), to be saline-alkaline (EC: 0.31 dS m -1 ), to have very low calcareous content (1.11%) and medium-level organic matter (2.13%). In terms of nutritional elements, it was determined that there were very low nitrogen (N) (0.07%), some phosphorus (P) (4.28 kg da -1 ) and zinc (Zn) (0.54 ppm), high potassium (K) (157.39 kg da -1 ) and iron (Fe) (5.31 ppm), and adequate amount of copper (Cu) (2.13 ppm) and manganese (Mn) (5.98 ppm). Organic carbon concentration of the soils was between 2.42 and 5.05 kg m -2 , and determined to be 3.76 kg C m -2 as mean. Inorganic carbon concentrations varied between 2.75 and 5.36 kg m -2 , and determined to be 4.08 kg m -2 on mean. In this case, the highest organic and inorganic carbon concentrations in the study area were found to be in areas where sage (Salvia officinalis) plant grew.

“…The collected soil samples were air-dried and ground to pass 2 mm sieve. Soil pH was determined in a 1:1 soil-water suspension by the glass electrode method, particle size analysis by the hydrometer method of Bouyoucos (1951) in which sodium hexametaphosphate (Calgon) was used as dispersing agent. Total organic carbon by the chromic acid oxidation procedure of Walkley and Black (1934 )and Grain yield (kg) The data generated were subjected to analysis of valiance (ANOVA).…”
