Utilization of Fish Farm Effluent for Irrigation Short Rotation Willow (Salix alba L.) under Lysimeter Conditions

Efficient utilization, treatment, and disposal of agricultural wastewater sewage sludge are important environmental risks. In our research, effluent water from intensive aquaculture was evaluated for the irrigation short rotation energy willow in a lysimeter experiment. Two different types their combinations were applied with weekly doses 15, 30, 60 mm, respectively. Our results revealed that implementing instead fresh could potentially increase yield due to its higher nitrogen content (29 N mg/L). The biomass irrigated coppice (SRC) plants between 493–864 g/plant, 226–482 268–553 g/plant dry weight during experiment period (2015–2017), However, chemical properties (Na concentration, SAR value) water, soil exchangeable sodium percentage (ESP) significant it can lead degradation long term. current study also investigated relationship composition plant tissue water. case K-levels clones, an increasing trend observed year-by-year. terms Na localized leaf parts, especially samples effluent.
