The soils contain less than 15 per cent gravel and kankar and less than 5 per cent cobbles and stones. Soil water may be too saline or alkaline to support optimum growth and development of different crops for economic yields. 15, p. 38, 2016. Land that cannot generate a net incremental value of production equivalent to or greater than the cut-off value would normally be classified as 'Not Suitable'. Copyright 2012 -- Science Publishing Group All rights reserved. In order to attribute net values to the production of each LUT, it is necessary to prepare full or partial crop or farm budgets. Available moisture retentive capacity is at least 12 cm per 90 cm soil depth. Citizenship is required. Highly productive land will, of course, bear greater investment costs than marginally productive land. Z. Agide et al., Analysis of water delivery performance of smallholder irrigation schemes in Ethiopia: Diversity and lessons across schemes, typologies and reaches, LIVES Work. October. This land use pattern will serve as the basis for locating the project's major water supply and drainage systems, and for calculating irrigation benefits. The land is suitable for many applications whether you are a retiring farmer or a first time lifestyler. 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. 128, no. The farm has 7 boreholes, 6 sun pumps and +/- 20 -x 5000 L water tanks, 1 x earth dam and water is piped to a 200 000 L Sink dam/ reservoir which again feeds tanks for domestic use, irrigation and livestock watering purposes. April, pp. 7. Supporting data elaborating on methodology and assumptions can be filed and retained for future reference. It must also be evident that (A) minus (B) is equivalent to the maximum permissible amount which can be spent on Area-specific Land Development (C), expressed in annual equivalent values. As explained in Chapter 1, land suitability evaluation is essentially an economic concept. The application of any formal economic analysis is, of course, seldom possible in the earlier stages of a land evaluation exercise when only rough estimates of development costs and of potential levels of productivity are usually available. 2007. As the topography and drainage factors are ideal, a variety of crops can be grown with optimum yield and profitability. where salinity is projected to increase in the absence of the project), deteriorating conditions need to be recognized in the sense that the budget for the 'without' situation represents a worse state than that of the present situation. They are shallow soils with depth varying from7.5 to 22.5 cm and of texture sand or clayey having available water holding capacity varying from 2.0 to 6.0 cm per 90 cm soil depth. The process of land suitability classification is the appraisal and grouping of specific areas of land in terms of their suitability for defined uses.
