Abstract:
This study was conducted in Peoples’ Cooperative Project farm, north
of Khartoum north at AlFaky Hashim area about 25 km north of
Khartoum north. The objectives of the study is to characterize the
soil of the farm and to determine its suitability for farming for the
production of field crops, fodder, vegetables fruits and mangos by
applying modern irrigation methods. The soils of the project farm
were described and sampled in the field at Auger observations and
profiles pits sites. The topography of this area is somewhat flat
including flooding soils from the River Nile, dominant by Dark Brown
in color. The Soils classified in this and a previous study as Entisols
.and the climate of the study area is arid
The morphological field studies revealed flooding soils with the
some clay contend in some horizons. The structure ranged between
weak angular to massive, slightly calcareous in the sub soils.
.Moderate drainage and slow permeability in the wet stat
The geomorphologic mapping unites of the soil have been identified
and mapped as three levels; Recent Alluvium, Semi-recent alluvium
.and Old alluvium
The occurred particles size distribution indicated that fine fractions
.of silt clay and silty clay loam in different sites and horizons
The soils were classified according to USDA soil taxonomy as Typic
Torrifluvents. The results of field descriptions and laboratory analyses
revealed that the soil of the farm is non-saline, slightly alkaline in
reaction with pH (1:5) ranging from 6.5 to 7.9 and ECe ranging from
1.6 to 0.3. The fertility status of the soils is poor due to their adverse
chemical and physical characteristics and susceptible to prolonged
.flooding specially in soil map unit SRA
The study recommended the soils of the farm require good soil
conservation practices, it recommended to enhance the soil aeration by
good tillage and management. Good farming systems such as bush fallow
iv
and good irrigation methods should be practiced for soil nutrient

control conditions are required. Better water control can be achieved
through the implementation of drainage along or in combination with flood
