الملخص

The impact of land use management systems is major process that plays akey role in reducing or aggravating desertification. Consequently, this studywas implemented to fined out the impact of land use management systemson private farms located south of Khartoum State. Some land degradationindicators (physio-biological) were used in order to assess the currentperformance status of these farms, mindful that such assessment was notconducted since their establishment.Soil samples were collected from four private farms using auger, besidesamples from uncultivated area as control. Samples were collected fromthree depths (0-30, 30-45, 45-60cm). Also, samples of water were collectedfrom the wells constructed in the farms for irrigation and drinking purposes.Statistical analysis indicated that there was a significant difference (P ≤ 0.05)in most soil characteristics in the area of the study. The study showed that theapplied irrigation system has led to secondary salinization in soil. It has beenfound that the value of ECe (3. 04 dSm-1) in the uncultivated area was similarto ECe value in the Korean Company Farm (3.38 dSm-1), because they usecentral pivot irrigation. Moreover, it was found that the ECe value in otherfarms ranged between (5.48dSm-1 to 8.47dSm-1), which reflected the improperirrigation system that led to increase of salts in the soil.Experiments showed that the increased quantity of Residual SodiumCarbonate (RSC) in the irrigation water led to accelerate the creation ofsodic pockets in soil, namely in Alhaj Ahmad farm.On the other hand, it was found that the appropriate land use pattern reducedthe amount of sand, consequently reduced the land vulnerability to winderosion. On the other hand, land use pattern reduced the bulk density of thesoil, the value of B.D was high in the uncultivated area and low in the farms.Analysis showed that the water was suitable for irrigation except in AlhajAhmad farm, where the quantity of Residual Sodium Carbonate (RSC)increased, which reflect the un-suitability of water for irrigation.Analysis has proved that the water in study areas is suitable for drinking andconforming with the standard specifications of the World HealthOrganization.
