Good practices and lessons learned

The lesson learned from the experiment is that we should consider direct seeding instead of transplanted seedlings. There should be acclimitazation for drought. We should also think about others trees such Acacia nubica which is also successful and drought tolerant. Incorporation of organic waste in desertiﬁed sandy dune soils increased its nutrient content and hence sustained biological ﬁxation of sand dunes.

Description

Wind erosion and sand dune are the main features of desertification in Sudan. Desertification and land degradation are the main constraint for agriculturral production and food security. Low water and nutrients holding capacity hinder sustainable biological sand dune fixation programm. The aim of this study is to improve the physical and chemical properties of dune soil in Elrawakeeb Dry Land Station using organic wastes as a fertilizer source and amendments, for sustainable sand dune stabilization program.

Expected outcome

Further information

Desrtification is a real threat in Sudan...and more effort is needed.

NWPOutcome

Incorporation of organic waste in desertiﬁed sandy dune soils increased its nutrient content and hence sustained biological ﬁxation of sand dunes. In addition the Salvadora persica plant grow well in the dune. the nutrients contents in the dune has improved. The programme is done as pilot study..in small dune. Seedlings of Salvadora persica L. were transplanted in the dune and grow well. The plants were irrigated with water from well in the area. After three years irrigation, we stopped irrigating the plant. The Salvadora persica tree died as a result of drought.
