Abstract
Agricultural soil science is a branch of soil science; it is food and fiber related to production regarding edaphic conditions deals with research. In this context, it is a department of agriculture component, thus soil agriculture also described as 19 yenfor the development of pedology in the century formerly, agricultural soil science (or edaphology) of soil science it was a single branch. 2006 yes as per the year, the soil of their agricultural potentialfor viewing purposes only bias of early soil science,as of 2006, pedagogy of the soil science professionand in popular settings defines. And nutrients. Soils have their chemical and heavily in physical properties differs. Leakage, weather and microbial activity such processes are various create different soil types. complete agricultural soil science follows the pattern. Terrain integrating ecosystems partly soil is examined, but manageable nature also recognized as resource. Agricultural soil science, soils chemistry, physics, biology and mineralogical composition as related to agriculture examines. Agricultural soil scientists use soil improve and diet and increases productivity of fiber crops develop methods. Soil for the importance of sustainability continued emphasis is given. Soil erosion, compaction, fertility such as depletion and contamination soil erosion continue to be intense are concerns. They are irrigation and drainage, tillage, soil classification, plant nutrition, soil fertility and other areas conducting research. Plant (and thus animals) produce maximization is the right goal however, sometimes it isit can come at a high cost, though is immediately apparent(produced by monoculture massive crop disease) or long periodic (eg chemical fertilizers and effects of pesticides on humans in health). A farmer soil scientist, sustainable methods and using solutions productivity can be increased come up with a plan, they are farmers to do that science, physics, chemistry, biology, meteorology and geography many sciences including have to look at the fields. ideal solution (TOPSIS) is prioritized through unity is a technique that provides, this is a multi-criteria decision analytical method. TOPSIS stands for (PIS). Short geometric distance alternative to select is the positive ideal solution; basically distance to have ideal solution of thought (nis) negative too long from is geometry. Of TOPSIS the assumption is even greater is, is coming or going the criteria are the same are increasing. Many parameters in scaling problems or criteria often improper dimensions normalizations due to having are generally required. Alternative taken as clay, sandy, silty, peaty, chalky and loamy. Evaluation preference taken as arsenic (As),cadmium (Cd),copper (Cu), mercury (Hg). From the result it is seen that peaty is got the first rank where as is the silty is having the lowest rank.
