The Mociar Forest Reserve has a great scientific interest due to the age of the oaks ranging from 400-500 years, which is why it is included in the protected area category. Over time, a series of studies have been carried out on the occurrence of the oak drying phenomenon in the Mociar Forest in order to develop plans for measures to prevent and combat oak drying. The main reason for this was to analyze the physical and chemical properties of soils. Considering the direct influence of soil characteristics on the development of forest species within the Mociar Forest, we proposed the creation of nine soil profiles located in areas considered representative of the studied area and the identification of the main physical and chemical parameters in the laboratory stage (the soil pH, the nitrogen amount, the total humus and C:N ratio variation). According to the four factors analysed a GIS spatial analysis model has been developed in order to identify the favourability and soil restriction for forest species in the studied area. It was also sought to obtain an overall picture of the distribution of these parameters on their qualitative classes as well as on the distribution classes of specific, dominant forest species. This was made possible by the use of G.I.S. technology and specific geospatial interpolation and spatial analysis tools.

The mountainous massif of Sicó, in the centre of Portugal, is anextensive area composed of calcareous Jurassic formations. Hillsidecalcareous soils, with high pH, present chemical restrictions to supportplant growth and are subjected to important erosion processes leading to their degradation if not protected by vegetation. In a first year of study some soil physicochemical characteristics have been measured in some geo-referenced locations of a larger design experiment and an exploratory spatial analysis has been performed. The objective of this study was to present some suggestions in order to give sustainable phosphorus fertiliser recommendations aiming to establish pastures in these soils and thus support traditional livestock activity. Ten years apart, those soil characteristics have been measured again in the same locations and comparisions have been made. The objective was to understand the variability of the soil properties under study in order to better adequate the fertiliser soil management regarding the area restoration.

The objectives of research are: to evaluate land suitability for housing based on soil characteristics; and to propose policy on the sustainable housing development in Bandung and West Land Bandung District. The method used in the spatial analysis is descriptive method based on several i.e. on data description of a case, circumstances, attitudes, relationships or a system of thought that became the object of research. The result of research as follows: 41.76% at fine zone residential lands, 44.81% at moderate zone residential good lands. Result of analysis give alternatives policies as set up the standardization the building coverage ratio, limited the conservation area to residential lands and others, increasing the conservation funding for decreasing natural accident disaster as flood, landslides etc.

This research carried out in Huong Vinh commune, Huong Tra town, Thua Thien Hue province aimed to identify types of land use and soil characteristics. Results showed that five crops are found in Huong Vinh commune including rice, peanut, sweet potato, cassava and vegetable. There are two major soil orders with four soil suborders classified by FAO in Huong Vinh commune including Fluvisols (Dystric Fluvisols<em>, </em>Gleyic Fluvisols and Cambic Fluvisols) and Arenosols (Haplic Arenosols). The results from soil analysis showed that three soil suborders including Dystric Fluvisols<em>, </em>Gleyic Fluvisols and Cambic Fluvisols belonging to Fluvisols were clay loam in texture, low pH, low in OC, total N, total P<sub>2</sub>O<sub>5</sub> and total K<sub>2</sub>O. Meanwhile, the Haplic Arenosols was loamy sand in texture, poor capacity to hold OC, total N, total P<sub>2</sub>O<sub>5</sub> and total K<sub>2</sub>O
