Wind, temperature, humidity, and precipitation data of 2014-2017 taken from 5 automatic weather stations established in Igdir province and its surrounding area were evaluated in terms of wind erosion. Wind frequency, monthly mean wind speed, and prevailing wind direction along with wind speeds of 8 m.sec-1 (10 m height), which is accepted as the threshold value in terms of wind erosion, and above were determined. For each station, monthly strongest wind, monthly average relative humidity, monthly average temperature, and average of monthly total precipitation were shown on the same graph and interpreted. As a result of processing and interpretation of the mentioned meteorological parameters; physical and chemical analyses and dry sieving processes were carried out by taking five different samples in five regions in the area, where the airport is located between Igdir and Tuzluca, and appears as a second potential wind erosion area. In the sampled sections of the second wind erosion area, sandy loam and loamy sand textures, 0.07-1.61 organic matter, neutral and alkaline pH values, and particle susceptible to wind erosion of 44.23-92.06% (<840 μ) were found.

This study was carried out with the aim of determining the effects of mulching on soil moisture and some soil properties. The experiment was conducted under field conditions in randomized block design in cultivated and non cultivated blocks with 3 replications. In the study, five different doses, 0 (control), 4, 8, 12 and 16 t/ha of straw mulch were applied to the field surface. The experiment consisted of one-meter-spaced 30 plots of 4 m2 (2mx2m) size each on a field of 304 m2 in total. With the aim of determining the progress of change in soil properties, disturbed soil samples were collected from the depth of 0-20 cm on each plot before and six months after the experiment; the samples were airdried, passed through sieve and analyzed. At the end of the experiment, tillage increased moisture held in soil and decreased organic matter, cation exchange capacity and aggregate stability. Soil moisture, organic matter, hydraulic conductivity, cation exchange capacity and aggregate stability were detected to increase with increasing mulch dose while the change in electrical conductivity, pH, bulk density and lime values was found insignificant.

This study was conducted on Turkey's second largest wind erosion area located in the Aralik-Igdir region. Plots of 500 m² including protected, less protected, and unprotected areas over a land of 12 km² having a 2-km width in the north-south direction and a 6-km length in the east-west direction were made and 48 disturbed surface soil samples (0-10 cm) were randomly taken as two samples (24x2) per plot. Erodible fraction of surface soil samples was determined based on dry sieving by using a vibratory sieve shaker. Estimated soil loss was determined by using the Wind Erosion Equation (WEQ). Surface soil textures of plots were sandy loam and loamy fine sand, organic matter contents were very low, lime amounts were medium to high, pH values were slightly to moderately alkaline, and EC values were essentially salt-free. The estimated soil loss for unprotected plots varied between 0-48.18 t ha-1 y-1. In dry sieving, the percentage of materials bigger than 0.84 mm was 0.48-30.47%, the percentage of materials bigger than 0.106 mm was 47.17-87.73%, and the percentage of materials smaller than 0.02 mm was 0.40-6.79%.
