As the topography and drainage factors are ideal, a variety of crops can be grown with optimum yield and profitability. They contain more than 65 per cent cobbles and stones of dia more than 75 mm and more than 70 per cent gravel and kankar with dia varying from 25 to 75 mm. T. Yitbarek, Physical Land Suitability Evaluation for Irrigation in the Lower Alwero River Area of Abobo, Western Ethiopia, American Journal of Agriculture and Forestry, vol. They are very shallow (< 7.5 cm deep) with variable soil texture and their water holding capacity is less than 2 cm per 90 cm soil depth. the value obtained by subtracting both the variable and fixed costs from the gross value of production on a given unit of land (Section 2.4); - Net Incremental Irrigation Benefit (NIIB), a measure of the potential increase in productivity of a unit area of land when developed under a specified plan, expressed in economic terms as an Annual Equivalent Value (see later in this Chapter). These lands are not suitable for sustained use under irrigation. A comparison is made using three farmer-financed options for area-specific land development costs (unimproved furrow irrigation, land levelling, sprinkler irrigation). Numerical 1, 2, 3, 4 and 5 denote land irrigability classes which are used for these appraisals relating them. The suitable land for irrigation from surface water was compared with small- to large-scale existing irrigation projects command areas for irrigation diversion in the basin. 910, 2013. In most areas of Western Australia, about three-quarters of the total soluble salt is sodium chloride, though this may vary in coastal and pastoral areas. - Increase water infiltration. 1/ Not applicable in economic analysis2/ On machinery and capital items having limited lives.3/ Not applicable in economic analysis.4/ At market wage rate.5/ Shadow-priced at half the market wage rate.6/ Establishes the maximum permissible area-specific land development cost. It is of two types: general purpose and special purpose. The application of any formal economic analysis is, of course, seldom possible in the earlier stages of a land . Due to the main limiting constraints of depth, slope, and sand dunes, there is currently a small area that is not suitable for irrigation. The Sustainable Irrigation Program undertakes a range of actions to improve on-farm water use. in a classification of 'irrigable' land. Plagiarism Prevention 5. 3.0 (2) Open until 5:00pm. Three alternative measures of land suitability class have already been defined in Chapter 2, namely: - Net Farm Income, i.e. Encourage best practice in the management of land and water. Example 1 shown on the nomograph represents an area that will become top producing land (Incremental Net Farm Income Rp 325 000) following an area-specific development cost expenditure of, say, Rp 200 000. Factors influencing cost: benefit ratio. Evaluation of Land Suitability for Irrigation Development and Sustainable Land Management Using ArcGIS on Katar Watershed in Rift Valley Basin, Ethiopia. The full or partial budgets described above provide an estimate of the net farm income per hectare attributable to a given farming system or LUT at various productivity levels under 'without' and 'with' project situations. This residential plot can be utilized once you pay the booking amount of Rs 100000. Values used for the nomograph are generated by determining the cut-off value, the net farm income values in farm budgets, and the range of permissible area-specific land development costs. The PI value for our samples was reported to range from 13.95 to 46.68, with an average value of 27.86. . ii. Such initial calculations may also help identify alternative LUTs, including possible cropping, irrigation and management systems, and the approximate amount which can be invested in land development.
