Abstract

This study aims at investigating the features of calcic cambisol soil which is composed in the old lake base of Uşak Province. According to the research principles of Geography, firstly, the factors that are effective on the composing of the soil are investigated. By transforming the effective factors into figures and maps, their relations for each other are put forwarded. In order to determine the features of the soil, eight soil samples were taken from 0-30 cm and 31-60 cm depths and at about 3 meters deep horizons were opened. After taking the necessary reports during these processes, the samples were sent to the full-fledged laboratory of Uşak Food, Agriculture and Live Stock Directorate. In the laboratory environment, the physical chemical features of soil (Ph, Total Salt, Na, K, Lime Organic Substance, Soil, Silt, Clay, Structure Class), the macro (P, Ca, K, Mg) and the micro (Cu, Fe, Mn, 2n) element distributions were studied. The results of the analysis put forwarded by the expert people were summitted to us according to the common protocol. The results of soil analysis were taken into multicriterion evalutions by the help of Geographical Information Systems and then they were transformed into maps. The analysis results were compared to the standart ranges come from different researches and then the range of element level in the soil was determined. The calcic cambisol Upper Miocene Pliocene composing Uşak Province city center was developed on the old limestones. Therefore, its content of lime is high. As it has a loamy structure, it has low yield value in general. Although it has not caused a problem so far, the soil of Uşak Province is more salty contented than the other types of soil. In the structure of this soil which has a slight alcalin reaction, the number of dissolved ions raises. Hence, they partly inhibit the development of the plants. Related to the over use of fertilizers and soil reaction, the level of potassium is very high. The calcic cambisol developed on an old lake warehouse has over lime content. Therefore, they are known as lime soil. This kind of soil producing intense agricultural lands has more organic substances compared to the other kinds. The content of beneficial phosphore and changeable potassium, magnesium and calcium are generally determined as middle level. While the content of ferrous is the middle level, the quantity of manganese and copper are sufficient. However, each of three elements is lessening towards the bottom. In the conclusion part of the study, solution offers to the questions arose during the research and the suitable ways of using the farmlands are proposed.
