| Abstract | ||||
| The main objective of this study was to evaluate the impact of irrigating three types of wood trees (i.e. Cupressus sempervirens, Corymbia citriodora and Khaya senegalensis) by treated wastewater as compared with irrigating by fresh water on their biomass growth rate as well as accumulation of different elements in the soil sites. Two experimental field trials were conducted over two consecutive seasons 2018 and 2019 at the two sites. The first site was in the experimental field at the Serapium Forest Plantation in Ismailia governorate, which was dedicated to the safe disposal of treated sewage water, planted with various wooden trees, while the second farm is located at Groppy Nursery in Giza Governorate- West Bank of the Nile where the fresh water(Nil water) was used for irrigation. The study was conducted on the growth of the wood mass above the soil surface of the three tree species. The results showed highly significant growth differences between both locations. The use of treated sewage led to a superiority in the growth of the living mass for tree species compared to those irrigated with fresh water, as it achieved the stock of the wood mass of trees that irrigated with treated sewage (2.68375, 2.44200 And 1.71693 M3 per/ tree) for Khaya senegalensis, Corymbia citriodora and Cupressus sempervirens trees, respectively. The trees showed that Khaya senegalensis gave the highest .values among the three types. Regarding the presence of minerals and their accumulation of soil under trees, the Serapium Forest Plantation has achieved the highest values for the accumulation of macro and micro-nutrients, as well as the highest percentages for the accumulation of minerals at all studied depths compared to soil samples taken from areas irrigation of freshwater trees. Therefore, continuous monitoring for soil, water, and plants analysis is necessary. | ||||
