Mapificación del grado de fertilidad de suelos mediante los sistemas de información geográfica sig del cantón Las Lajas provincia de El Oro

In the Ecuador the Systems of Geographical Information are using (SIG) like an alternative to investigate, to develop and to present options and power to either solve problems that are of a lot of importance in different fields, for the planning or the resolution of some matter of national or local type. The elaboration of a database georeferenciada of different elements that you/they are in the floor and that they are necessary for the nutrition of the plants, he/she can help us to plan and to take a control of the correct handling of the floors. By means of the prosecution and interpretation of the results of the analyses you could determine the current state of the floors and with the software you could process the data and to create the maps which are illustrative and explanatory. The objectives were the following ones: 1. To determine the grade fertility of the floors by means of texture analysis, pH, organic carbon, organic matter, capacity of cationic exchange, Ca++, Mg++, K+ and changeable Na+, N, P, K and complementarily Faith, Cu, Zn, Mn. 2. To elaborate by means of the systems of geographical information the texture maps, fertility, pH, organic carbon, organic matter, capacity of cationic exchange, Ca++, Mg++, K+ and changeable Na+, N, P, K, Faith, Cu, Zn and Mn of the canton The Flagstones. The Canton The Flagstones, politically, it is located in the county of The Gold-Ecuador; he/she has a surface of 301,55 km2 that is equal 5,15% of the total surface of the county approximately, you limit them they are: to the north with the Canton Sands; to the south with the county of Loja; to the east with the Cantons Marcabelí and Avocados county of Loja, to the west with Peru. The protocols for the analyses of floors were: for the organic matter, Walkley and Black, for the mechanical analysis, Bouyucus, for the capacity of cationic exchange, Formaldehyde, for the changeable bases Na+, Ca++, Mg++, K+, the macro and micronutrimentos N, P, K, Ca, Faith, Cu, Zn, Mn, the espectrofotómetro of atomic absorption: and, pH, conductometer. It was obtained the following summations: The textural class that prevails the floors of the canton The Flagstones is the Sandy Franco with 51,47% of the surface of the canton. The content of organic matter of these floors in its majority is low. The capacity of cationic exchange in these floors prevails the securities in the half range, since I represent 55,88% of the surface of the canton. The nitrogen levels are very low, the levels of the elements changeable Magnesium and Calcium are very high in the floors, while the levels of changeable Potassium are very high and changeable Sodium is low and means. The macronutrientes and micronutrientes had an irregular distribution and of varied concentrations. The floors of the canton The Flagstones spread to the acidity. The maps were elaborated in a satisfactory way.
