Kuzgun Barajı Sulama Alanında Agro-Ekolojik Sınırlar ve Arazi Kullanım Planlaması
Atatürk Üniversitesi Ziraat Fakültesi Dergisi, 2017
Soils are a major source which restricts the agricultural production because of the limited and non-producible properties. So, it is very important to be evaluated in a manner appropriate to the characteristics of farm lands. This study was undertaken to prepare the agro-ecological zones and the land use planning of farmlands, on the irrigation area of the Kuzgun Dam which is constructed by State Hydraulic Works in Erzurum. Factors affecting crop production (climate, soil texture, salinity, alkalinity, permeability, groundwater level, erosion grade, soil profile depth, land slope, farmer preferences) in research area were considered and multiple query was made. As a result of the query, it was obtained that soil profile depth and slope of the land will play dominant role for crop pattern and the others will have low-impact. Probable land use forms of the farm lands were estimated base on dominant factors according to the geographic information system (GIS) method, and some suggestions were presented for the crop production. As a result of this study, cereals, forage crops, natural pasture and afforestation areas were identified in the fields with production limitations for Kuzgun Dam irrigation area. In areas without production limitations in terms of soil properties, two factors, climate and farmer preference, were effective.

Alexandria Science Exchange Journal
The proficient management of the available natural resources of Egypt is necessary in order to save food demands of the rapidly increasing population. In the processing of land use planning, estimating the agricultural land potentiality is important footstep where the agricultural resources are so limited. Toshka spillway area is one of the greatest promising area for horizontal agricultural extension where the fresh water is available. The main goal of the current study is to produce land priority map based on different thematic layers of some soil parameters that affect on or control the agricultural potentiality by designing a suitable GIS-based model for data integration with relevant logical condition of the area along Aswan Toshka District, south of Egypt. The parameters taken into consideration were slope, soil texture, soil depth, gravel content, calcium carbonate, soil salinity, and soil reaction. By using GIS environment, these parameters were interpolated in order to recognize their spatial variability by differentiating each property as sever, moderate, slight, and no limitations. Accordingly, The analysis showed that the soil depth, soil gravel, and soil reaction were the major limitation factors comparing with the other soil factors. The priority of Land Suitability Potential Index (LSPI) for Agricultural purpose was calculated by the contribution of the abovementioned parameters. The potentiality was categorized as not suitable, marginally suitable, moderately suitable, and highly suitable. These classes were attained by integrating the different thematic layers with corresponding weights in geographical information system (GIS). The output of study indicated that the study area can be mainly described as moderately suitable where it covers about 81.04 % of the total area, while highly suitable, marginal suitable and not suitable attained the lower converge 9.23, 9.01, and 0.72 %, respectively. The study concluded that any given area can be categorized into spatially distributed agricultural potential zones based on the soil characteristics and terrain properties by the profound assist of geographical information system (GIS).

Land evaluation based on human, economic and physical resources is an important tool for attaining proper land use planning of various agro-ecological zones especially in arid terrestrial ecosystem condition area to ensure that land is not degraded and that it is used according to its capacity to satisfy human needs for present and future generation. The aim of this research was to assess land suitability for the production of major crops in arid terrestrial ecosystem. The study area was carried out Ayrancı district of Karaman province is about 4760 km 2 and located between 577076 m-596768 m east and 41541331 m-4174001 m north coordination. Elevation of the study area locates between 991 m and 1774 m from sea level and long term annual average precipitation and temperature are 330.8 mm and 12 o C. According to Newhall simulation model, it was determined that soil temperature regime is mesic and moisture regime is weak aridic. The land mapping units were primarily described and land characteristics and qualities were determined using 1:5.000 scaled soil maps of the study area. Land use types to be considered were described and their land requirements were determined. The land requirement of the land use types were compared with the land characteristics and land qualities of land mapping units. The results of the matching process combined with those of assessment and produced a classification showed the suitability of each land mapping unit for each relevant land use type. The agricultural suitability maps prepared revealed that only 8.4 % of the study area soils was not suitable for agricultural uses, 57.2 % of the soils was best suitable for agricultural uses. In addition, 70515.8 ha of the total study area was not suitable for horticulture cultivation whereas, 9859.1 ha was not suitable for field crop cultivation due to the unfavorable land and soil conditions. Moreover, about 35.4% of the total area was found non suitable for vegetable crops in the study area.
