“…Moreover, germination process, plant growth, nutrients uptake by the plants and both water and fertilizers use efficiency were beneficially increased by mixing the plant pits in sandy soil with hydrogels (El-Hady and Wanas, 2006). According to many authors, superabsorbent polymers also have a beneficial effect on plant nutrient uptake, and increase the saturation of the sorption complex with bases, which prevents leaching losses of nutrients, thereby increasing the effectiveness of fertilization, and conduces to environmental protection (Guiwei and De Varennes, 2009, Kim et al, 2010and Mikiciuk et al, 2015. Bres and Weston (1993) studied that the effect of incorporated hydrogel amendments (Hydro source and Agri-gel, at rates of 1, 2, or 3 g L -1 ) to a soil less growth medium on ammonium, nitrate, and water retention and tomato (Lycopersicon esculentum Mill.)…”
