The soil should not suffer from erosion, so that fertile soils remain intact in heavy rains and winds. Some of the feasible solutions such as intensification of cultivation with double cropping in suitable environment, proper nutrients, water, pest and post-harvest management practices must be pursued on war footings. 3. pp. Net farm income may be a sufficient measure for a classification of 'provisionally-irrigable' land, before reliable estimates of common project costs and land development costs are available. GZELYURT. They are 45 to 90 cm deep, loamy sand or clayey in texture. On many rainfed areas, the future situation without the project can be represented by a single budget (or a limited few) if the present situation is fairly uniform and stable throughout. Available moisture retentive capacity is at least 12 cm per 90 cm soil depth. Before uploading and sharing your knowledge on this site, please read the following pages: 1. In special cases, a social rate of discount may be appropriate in lieu of a discount rate related to the opportunity cost of capital. Then the surveyor finds another combination of surface features and soil properties. The construction of a nomograph is quite simple. as S1, S2, etc.) The application of any formal economic analysis is, of course, seldom possible in the earlier stages of a land . Variable Costs (from schedule C, see Table 20 for details): 1/ Land Productivity Index Level (1.0) represents the best quality land. Account Disable 12. This approach contrasts with that adopted by the USBR which classifies land according to its 'payment capacity'; this is essentially a measurement of financial impact of irrigation development on the income of the typical farmer (see Chapter 10). This study was conducted in the Abbay basin of Ethiopia to evaluate land suitability for irrigation considering both surface and groundwater sources using the analytic hierarchy process. Final selection of LUTs for the 'irrigable' land Soil suitability was assessed using parameters such as drainage, texture, available water storage capacity, pH, physico-chemical organic carbon, salinity, sodicity and soil depth. - To improve germination. Table 28 illustrates the financial verification using financial criteria pertinent to the farm. In these budgets: ii. These factors influence land development needs and costs, design of on-farm water conveyance systems, erosion hazards, crop adaptability, drainage requirements, water use practices, and selection of management systems. The economic consequences of changes in physical productivity and costs of production will demarcate a boundary or cut-off point between land which is suitable for irrigation and land which is not.
