National updates on soil by SWERI practical researches

2. National updates on soil for maximizing the use of land and water resources

1- The delineation of Delta apex versus pro Delta on the base of physiographic
approach, topography and soils
Soil profiles

3. Reasons:
- Pro-delta have thermic temperature regime comparing to Delta apex as mostly have hyperthermic temperature regime so,
loss of water by evaporation is less from soil surface .
-Soil hydraulic conductivity values in Pro-delta are low and very low, while in Delta apex are mostly high, which drains more
water without use
- Enhancing the efficiency of the added nutrients uptake in the root zone as well as reducing the loss of these nutrients that
most probably are drained to contaminate the ramification flow of water canals in delta apex.
- Drip irrigation for crops of high value for national economy such as cotton and maize or for economical cash crops such as
vegetables and fruit trees. They are adequate as row crops, individual plants, or trees.
- Protecting the pro-delta from the sea water intrusion
- Feeding the semi restricted storage of under ground water in the sub stratum of River Nile Pro Delta by using surface
irrigation
2-Adapting the irrigation system for saving water
( surface irrigation in Pro delta but drip one in Delta apex)

4. 3- Adapting cropping patterns using land suitability assessment

5. National updates on soil for monitoring land degradation Impact on A Unique
Agrobiodiversity's
(Case study : Siwa Oasis)
Siwa should be considered as a Cultural Landscape as well as to be a protectorate being reflects the
interactions between indigenous people and their natural environment

6. The case study aims to update the spatial and the levels of land degradation in order to reduce its
impact for improving the environmental conditions, increasing the productivity level to improve the
social and economic status. Protecting the agro-ecosystems in Siwa Oasis is highly require.

7. 2 Catching up the physiographic features as affected by waterlogging in the years 2018

8. Recommendations
- Uncontrolled expansion of surface irrigated agriculture accelerated bonding and
waterlogging on its unique agrobiodiversity.
- Frequent data for monitoring the land degradation should be based on tracing the
directions of water flow and its infiltration in the cultivated areas and their
outskirts.
- Ecosystems stability and protecting natural resources should be realized by a
better governance of its water and land resources.
- For successful improvement and irrigation system modification, collecting small
land tenures within large sized fields is highly required for realizing a commercial
scale.
In case of temporarily keeping the traditional current cultivation under surface
irrigation, cultivation expansion must be conditioned to be managed under drip
irrigation in aeolian plain.
