Cultivation of mango trees in reclaimed desert regions of Egypt
2017
Oosthuyse, S. A.
Mangoes are successfully grown in desert land-reclamation regions of Egypt, where the environmental conditions are particularly harsh. The soils often comprise more than 90% sand, cation exchange capacity is exceedingly low (3-5 meq 100 g‑1 soil), and soils and irrigation waters are saline (electrical conductivity (EC) ›1.5 dS m‑1). High levels of calcium carbonate and bicarbonate in the irrigation waters and soils impart high pH (7.5-8.8). Soil EC varies daily, the extent depending on the degree of evapotranspiration and the weekly irrigation frequency and amount. Prolonged hot winds, low humidity and excessive heat add to the difficulty of growing mango. Heat-and wind-protective measures, management of soil EC, fertigation program choice and foliar nutrient spraying are considered in the present paper.
