Explanations of interest and discounting calculations whereby monetary values are manipulated into various time-formats are given in standard economic textbooks. Terrain suitability was evaluated based on the slope of the land derived from a digital elevation model (DEM). Suitable soil conditions for irrigation may be summarised as follows: The soil should be moisture-retentive type so that it may feed the crop for a considerable time. Reasonably price, this residential land is located in the preferred residential area of Allithurai. The land suitability parameters such as soil properties, slope, land use and land cover were used to identify the suitable irrigable land. The methods used in the study broadly follow the framework of the Food and Agriculture Organization of the United Nations (FAO) for land suitability evaluation. Land suitability assessment for irrigation is a very important tool not only in terms of agriculture development planning, but also to overcome the global problem of water scarcity. Irrigation land suitability analysis is given to the physical and chemical properties of soil and topographic (slope) factors in relation to methods of irrigation considered (FAO, 2007; Haile . Although these sites have good groundwater recharge structure, they are often limited. 83. The 150 acres of land at the center has diverse soil types and utilizes Artesian water rights making it suitable for growing a variety of perennial and annual crops. However, future revisions and adjustments can be reduced significantly by making early estimates of incremental net farm income and cut-off values between 'Suitable' and 'Not Suitable' land. T.
