Üçharman (Divle) village of Ayrancı district in Karaman province, which faces
arid climate and problematic soil issues, in collaboration with Konya Selçuk
University and the Provincial Directorate of Agriculture and Forestry.
In this study, structures such as rangeland-type terraces, dry stone
thresholds, cage wire thresholds, sack setts, stone collection, and sieving
were done for soil conservation and water harvesting purposes (Acar, 2023).
In the study area, which has a heavy clay silt and occasionally old sandy
soil structure, there is no salinity problem; however, the soil has a high lime
content and is poor in organic matter. The area has the continental climate
characteristics of Central Anatolia. In the rangeland-type terraces and
observation pits, the used species were steppe grass (Kochia prostrata),
saltbush (Atriplex canescens), Anatolian lycium (Lycium anatolicum), tamarisk
(Tamarix sp.), nitrebush (Nitraria schoberi), goji berry (Lycium barbarum),
hawthorn (Crataegus spp.), mulberry (Morus sp.), walnut (Juglans regia), field
elm (Ulmus minor), oleaster (Elaeagnus sp.), sessile oak (Quercus robur),
and lavender (Lavandula angustifolia). In addition, herbaceous species that
can adapt to these rangelands include sainfoin (Onobrychis sativa), alfalfa
(Medicago sativa), garden burnet (Poterium sanguisorba), dogtooth grass
(Cynodon dactylon), smooth brome (Bromus inermis), and vetch (Vicia sativa).
As a result of the implemented practices, it has been observed that the area
with poor rangeland quality in the protected rangeland has been transformed
into an area with moderate rangeland quality. In the rangeland dominated
by a continental climate and erosion, after two years (2022), it was found that
the area covered by plants in the application site (average surface coverage
rate: 62.5%) was higher than that in the area outside the application (average
surface coverage rate: 25%). Additionally, within the application area, it
was determined that the largest proportion of the botanical composition
belonged to the Poaceae family (average surface coverage rate: 66.6%) (Acar,
2023). Again, among the drought-resistant and high root/stem ratio shrub and
semi-shrub species that can better adapt to continental climate conditions,
the four-winged American saltbush and steppe grass in its form have adapted
significantly to the site (Acar, 2023).
