The Mediterranean region faces significant water scarcity, a challenge intensified by climate change, impacting both agricultural productivity and quality. High sodium levels in irrigation compromise soil structure, leading to reduced crop yields economic strain. This study investigates the use of sustainable adsorbents derived from residues (almond shell, eggshell, pumice) for removal water. These materials, widely available Mediterranean, support circular economy principles repurposing biowaste address challenges. Adsorption experiments were conducted using real water, capturing complexity its physicochemical properties evaluate effectiveness these biosorbents under practical conditions. A Central Composite Rotational Design (CCRD) was applied optimize adsorption parameters, focusing on adsorbent concentration, agitation, contact time. Kinetic studies indicated that adhered pseudo-second order model, suggesting chemically controlled process. Isotherm analysis, with strong fit Jovanovic confirmed predominantly monomolecular mechanism across all adsorbents, while Freundlich model highlighted site heterogeneity. Microscopy energy-dispersive X-ray spectroscopy (EDX) revealed structural modifications before after treatment. porous internal structure almond shell displayed retention, calcified eggshell surface showed high initial efficiency but rapid saturation. Pumice, noted extensive porosity, sustained capacity even deposits formed during research demonstrates potential biowaste-derived efficient complex aqueous systems, offering viable solution agriculture improved management regions.

This research examined how zearalenone (ZEN) and nanozeolite (NZ) influence the physiological biochemical characteristics of arugula under regulated deficit irrigation (RDI) in a controlled greenhouse setting. A split-plot experimental design was implemented, with main plots representing two levels (100% 70% field capacity) subplots featuring varying concentrations ZEN (60, 120 ppb), NZ (1.5, 3 ppm), control group without any additives. The findings indicated that both treatments significantly enhanced plants' resilience to water stress by improving metrics such as maximum photosystem II efficiency, photosynthetic gas exchange, plant relations, shoot root fresh weight, proline levels, superoxide dismutase (SOD) activity. Notably, treatment at ppm emerged most effective, resulting 284% increase net photosynthesis rate, 200% enhancement use efficiency (WUE), 433% decrease transpiration 119% reduction electrolyte leakage compared irrigated capacity. Furthermore, ppb also demonstrated significant improvement conditions, ranking second effective option after ppm. study underscores potential these sustainable methods boost crop productivity water-scarce environments.

Efficient boron removal from irrigation waters is crucial for sustainable agriculture, as elevated levels of can be toxic to many plants, limiting growth and crop productivity. In this context, the present study investigated sorption equilibrium using zeolites in two types aqueous matrices: a synthetic solution containing only natural waters. Through application various isothermal models (Langmuir, Freundlich, Sips, Toth, Jovanovic, Temkin, Dubinin–Radushkevich, Redlich–Peterson), efficacy zeolite under controlled real conditions was evaluated. The results indicated notable difference behavior between matrices, reflecting complexity heterogeneity interactions boron–zeolite system. solution, Freundlich model provided best fit (R2 = 0.9917), suggesting heterogeneous multilayer sorption, while Sips showed high describing both evidencing its capability capture complex nature interaction different environmental conditions. However, waters, Jovanovic demonstrated most accurate 0.999), highlighting importance physical sorption. These findings underscore significant influence water matrix on agent, emphasizing need consider specific composition design treatments. Additionally, stress selecting appropriate predict behavior, which developing effective treatment strategies. This provides basis optimizing agricultural industrial applications, contributing more efficient processes.
