Abstract
The aim of study is to estimate the impact of crop rotation duration on sandy soil characteristic nitrogen and organic carbon component in soil. Sample collected from northern Darfur state (Alkowma) using GPS techniques, from different Auger, profiles, from bare soil and planted farm (same years) soil physical and chemical analysis Was performed at Sudan University Laboratories, mechanical analysis result shows that according to texture triangle it is sandy soil with max (81- 87)%, clay percentage is between (12-14) while silt range (0-4) soil PH and EC the PH reaction (7.6 - 8.2) EC range (0.1 -0.3), soil cations and anions the high amount of ca +mg is (3.1), when Na range between (2-5) , K is very few ( 0.05 -0.2) soil bicarbonate in sup surface (0.6-1.2) and in the surface (0.8 -1.8),N is very low (0.02) ,while P range between (.05 -1.5) CEC in soil (4.84 - 8.71).
