That was to perform a determination of land suitability classes for agricultural land uses in Ankara Imrahor valley and vicinity with this study. First of all detailed survey and mapping of research area was performed with aid of satellite data and topographic maps then four different soil serials and their fourteen different mapping units were described. For this units, 38 different land uses were describe as their soil and meterological properties and calculated their suitability for this region and determined and mapping their land suitability classes for agricultural purposes.

Biomass is a geographically dependent renewable resource which can be used for production of fuels and chemicals. This study develops a methodology for determining the suitable locations, optimal sizes and number of biomass-based facilities for a particular region through transport cost optimization which is applied for locating pellet plants in the Province of Alberta. The methodology also includes computation of local optimal size and cost of pellet production considering road network and spatially varied biomass.

Nature conservation is a very important issue in the sustainability assessments and spatial planning context. Knowledge of the suitability of the land to behave as an ecological corridor thus provides very significant input to land-use planning. Nature conservation and land-use planning are by their nature spatial problems.

Land suitability evaluation can assist in the efficient use of land resources at a regional level. This is an important issue because of the pressures that an increasing population and economic growth have put on limited land resources. Matter-element theory, which was first put forward by the Chinese mathematician Cai Wen, has shown potential for solving incompatibility problems.

Vegetable production has an increasing importance in most of the Asian countries. The leader in production per capita is China followed by South Korea, North Korea and Vietnam. In Vietnam, vegetable production is at the moment on 4th place of all agricultural commodities. In the past, in Vietnam as in other South-East-Asian countries, the production of rice, sugar cane, cassava and maize often as monoculture was typical.

Vegetables are mostly grown in mountainous areas with an altitude >400 m a.s.l., such as Temanggung, Central Java. The steep slope farming considers very little environmental suitability and sustainability. This study was conducted in 2004, covering a total area of 87,223 ha. Soil samples were analyzed for soil texture, pH, C, N, P, K, CEC, exchangeable cations, and base saturation. Soil characteristics data were used for land suitability evaluation for vegetables crops using the Automated Land Evaluation System (ALES) program.

Identifying potentially suitable lands for cultivated crops is economically crucial. Geographical Information Systems (GIS) and Remote Sensing (RS) are very significant tools in achieving this goal. In the near future the Sanliurfa - Suruc Plain can be more valuable for the people of the region in terms of both crop variety and economical perspective once the irrigation is started and more than one crop each year is harvested. Pistachio is one of the chief productions among others that are well adapted to the conditions of the region.

In this study, great soil groups, erosion classes and land capability classes of Tokat province were digitized and analyzed by using geographic information systems (GIS). Settlements, bare rocky areas and water surfaces like reservoirs or lakes were excluded from the evaluation.

The aim of this study is to determine soil quality of the Kırsehir - Çiçekdağ Farm State Soils using parametric method. In parametric method, some physical and chemical characteristics of the soils such as texture, salinity, alkalinity, soil reaction, structure, carbonate content, cation exchange capacity, soil fertility, and some soil environmental properties of the soil mapping units such as slope, stoniness, rock fragments, gravel contents, erosion, drainage and precipitation were used.

The aim of this study was to determine suitable lands for agricultural use in the Yusufeli district of Artvin city (Turkey), where the current agricultural land in the district center and 3 villages will be completely inundated while the land in 22 villages will be partially inundated due to three large dams currently being constructed. The “Analytic Hierarchy Process (AHP)” method, commonly used in land use suitability analysis, was utilized in this study.

The article aims to analyze suitability of land selection for cultivation of sugar beet in Slovakia in the period from 2008 to 2012. The results confirmed, that there are enough soils suitable for sugar beet growing in Slovakia. The area of sugar beet cultivation is conditioned by the presence of only two sugar rafineries, which are in operation, in Sered and Trencianska Tepla. The most productive soils in the climatically most suitable areas of Slovakia are chosen for growing sugar beet.
