- W38465265 abstract "Vertisols (heavy black clay soils) cover some 43 million hectares comprising 19% of total land area in Sub-Saharan Africa. Nearly 30% of the Vertisols area is located in Ethiopia alone, particularly in the highland region (Mohamed Saleem, 1995). Vertisols occupy about 12.7 million hectares in Ethiopia, of which 7.6 million hectares (approximately 60 percent) are in the highlands (Tekalign et al. 1993). The highlands cover 40% of the total landmass of the country but account for about 95% of all cultivated land. Hence, the importance of Vertisols in the country is unquestionable. However, most of the Vertisols suffer from excess water and poor workability and are also underutilized, and largely used for dry season grazing (Srivastava et al, 1993). Potentially, Vertisols are productive soils, but they are not easy to cultivate due to their poor internal drainage and resultant flooding and water logging during the wet season which contribute for lower crop yields. About 2 million hectares of highland Vertisols are currently being cropped. This means presently only 25% of the 7.6 million hectares Vertisols in the highlands are cultivated. The common crops grown on Vertisols are tef (Eragrostis tef), wheat (Triticum spp.), barley (Hordeum vulgare), faba bean (Vicia faba), field pea (Pisum sativum), grass pea (Lathyrus sativus), chikpea (Cicer arietinum), lentils (Lens culinaris), lineseed (Linum usitaissium), noug (Guizotia abyssinica) and fenugreek (Trigonella foenum-graecum). But the yields of these crops are quite low on the vertisols due to waterlogging and unavailability of improved technology." @default.
