the development of a mango orchard planted in a warm arid climate zone can be vigor, and it can produce high quality yields. Occasionally, soil existed in the arid climate zone might be calcic or sodic, subjecting roots to high pH and poor structure, limiting tree development and reducing yield and quality. Applying ODEM substrates by the FEEDING CANAL technique allows trees to enjoy the high soil water capacity together with the optimum pH and the air content through the ODEM substrate. Planting the young trees into pits or canal containing an ODEM substrate enables excellent conditions for root development and encouraging rapid development for long lasting high quality yields.
