| Abstract | ||||
| The aim of the study was to evaluate the land capability and suitability for some crops through determining soil physical, chemical properties and fertility in some soils of East Nile Delta in Dakahlia Governorate by using ASLE program and GIS techniques. ASLE program was used for calculating land capability and suitability for some field crops, vegetables crops and fruit trees with a total of 15 crops. For this purpose, 15 soil samples were randomly distributed within the studied area at a depth of (0-30, 30-60 and 60-90cm), which were subjected to physical and chemical analyses. Results indicate that the studied area was classified into two soil classes (i) excellent-C1 and (ii) good-C2. While, the land capability was fit into two classes: I- C2 (good) and II- C3 (fair). Concerning land suitability, studied crops can be grown in these soils. These crops were classified according to land suitability of studied area into three classes: (i) S=very suitable (wheat, rice, maize, sugar beet, alfalfa, barley, faba bean, pea, cotton, potato, grape, and citrus), (ii) S3= moderately suitable (tomato) and S4= marginally suitable (onion and pepper). The suitable field crops could be arranged by preference as: sugar beet < wheat < rice < barley < maize < faba bean < cotton < alfalfa < onion. While vegetables crops arranged by preference as: pea < potato < tomato < pepper < onion. Meanwhile, grape was the optimum fruit trees followed by citrus. | ||||
