The effects of tillage on soil water content in dry areas

Annual rainfall is less than 500 mm of rainfall in the dry farming regions in order to be stored in the soil processing. At the time, and is provided with a sufficient number of the version of weed control, leveling a good soil is obtained, the temperature of the soil evaporation will be blocked, and capillarity corruption prevented erosion. Some dry land farming areas is 7-8 times a year. As a result of the false and incorrect versions of the soil organic matter content decreases, due to the heavy traffic and rainfall feeds into and hardens. Also, the more time the soil impermeable layer consists of the processing of terrain plow deep, it's broken, you need to increase water permeability changes in the ground. Our country's (Turkiye) Southeastern Anatolia region, especially during the period of erroneous releases summer soil cultivation of pistachios to crack and evaporate the water accumulated in the profile. In this region, the soil is less to prevent evaporation and mulch practices are required to do. Usually in the winter and spring to gain ground in both the water and the soil is completely dry in order to struggle for and type weeds, cracks and prevent evaporation of water to close the land sliding. In our region the soil structure and the orchards slope, vegetation, depending on the year, to a loss of between 40-100 tons per hectare. Soil processing by lose ground is important for quantities of soil and water losses in every year. The importance of the land in agricultural production processing topics, manufacturers, increases productivity with timely and accurate processing of applications on soil. In addition to the increase in the efficiency of handling soil erosion by the soil protection and control of soil water contents are benefits such as to conservation. In this study, tillage, reduced tillage in dry farming areas, mulching and soil moisture content will rely upon. (C) 2015 The Authors. Published by Elsevier B.V.
