Land Suitability Classification

	Land Suitability Classification The Land Suitability Classification is a soil evaluation method, developed by FAO. FAO stated that Land suitability is the fitness of a given type of land for a defined use. The land may be considered in its present condition or after improvements. The process of land suitability classification is the appraisal and grouping of specific areas of land in terms of their suitability for defined uses. FAO. Chapter 3. http://www.fao.org/docrep/X5310E/x5310e04.htm Structure Each category retains its basic meaning within the context of the different classifications and as applied to different kinds of land use. Four categories of decreasing generalization are recognized: I. Land Suitability Orders: reflecting kinds of suitability. II. Land Suitability Classes: reflecting degrees of suitability within Orders. III. Land Suitability Subclasses: reflecting kinds of limitation, or main kinds of improvement measures required, within Classes. IV. Land Suitability Units: reflecting minor dif ...

picture info	Soil Soil, also commonly referred to as earth, is a mixture of organic matter, minerals, gases, water, and organisms that together support the life of plants and soil organisms. Some scientific definitions distinguish dirt from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid collection of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three- state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Evaluation In common usage, evaluation is a systematic determination and assessment of a subject's merit, worth and significance, using criteria governed by a set of Standardization, standards. It can assist an organization, program, design, project or any other intervention or initiative to assess any aim, realizable concept/proposal, or any alternative, to help in decision-making; or to generate the degree of achievement or value in regard to the aim and Goal, objectives and results of any such action that has been completed. The primary purpose of evaluation, in addition to gaining insight into prior or existing initiatives, is to enable Human self-reflection, reflection and assist in the identification of future change. Evaluation is often used to characterize and appraise subjects of interest in a wide range of human enterprises, including the arts, criminal justice, foundation (charity), foundations, non-profit organizations, government, health care, and other human services. It is long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Environmental Degradation Environment most often refers to: __NOTOC__ * Natural environment, referring respectively to all living and non-living things occurring naturally and the physical and biological factors along with their chemical interactions that affect an organism or a group of organisms Other physical and cultural environments Ecology, the branch of ethology that deals with the relations of organisms to one another and to their physical surroundings Environment (systems), the surroundings of a physical system that may interact with the system by exchanging mass, energy, or other properties. Built environment, constructed surroundings that provide the settings for human activity, ranging from the large-scale civic surroundings to the personal places Social environment, the culture that an individual lives in, and the people and institutions with whom they interact Market environment, business term Arts, entertainment and publishing Environment (magazine), ''Environment'' (magazine), a p ...

	Pedology Pedology (from Greek: πέδον, ''pedon'', "soil"; and λόγος, ''logos'', "study") is a discipline within soil science which focuses on understanding and characterizing soil formation, evolution, and the theoretical frameworks for modeling soil bodies, often in the context of the natural environment. Pedology is often seen as one of two main branches of soil inquiry, the other being edaphology which is traditionally more agronomically oriented and focuses on how soil properties influence plant communities (natural or cultivated). In studying the fundamental phenomenology of soils, e.g. soil formation (aka pedogenesis), pedologists pay particular attention to observing soil morphology and the geographic distributions of soils, and the placement of soil bodies into larger temporal and spatial contexts. In so doing, pedologists develop systems of soil classification, soil maps, and theories for characterizing temporal and spatial interrelations among soils. There are a few ...
