    Effects of drainage and land consolidation on sustainable agricultural productivity: Changes in kos 6th section
    (PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2019) Celebi, Muhittin.; Egilmez, Samet.
    The main obstacles to the sustainability of agricultural productivity in arid and semi-arid areas are the tendency of conditions to salinization, wind erosion and degradation of plant water balance. In this study, it was aimed to determine the usage level of the potential of the land consolidation, which is applied within the context of the KOS 6th Section project in semi-arid Konya plain, in preventing the wind erosion. It was also aimed to determine the changes created by the closed drainage on some soil parameters in Konya-cumra-Turkmencamili between 1998-2001-2016 period, and the reduction rate in salt level. For this purpose, the analysis results of soil samples obtained from 0-30 cm, 30-60 cm and 60-120 cm depths during the planning phase before the establishment of the drainage in 1993 and after the establishment of the drainage in 2001 and 2016 were compared; furthermore, the positions of the blocks established during the land consolidation were examined in terms of the prevailing wind direction leading to erosion. With the drainage application, during the period between 1993 and 2016, the highest and lowest EC values of the soil samples decreased respectively from 2.43-25.0 mmhos/cm to 0.680-2.880 mmhos/cm in 0-30 cm depth and from 2.63-50.00 mmhos/cm to 0.584-4.190 mmhos/cm in 30-60 cm depth. The periodic decrease rate of salt level in soils according to years was higher in the first 3 years between 1998 and 2001 than those in the range of 2001-2016. It was determined that during the land consolidation, 78 blocks (79%) were not planned in a perpendicular position to prevailing wind directions. With this block layout, since it is not possible to establish a windbreak facility in such a way that it is serially and perpendicular to the prevailing wind direction that will cause problems in the future, the effective protection distance of windbreaks will partly fall from 12 trees' height to 8 trees' height and below.
