Durability indicatives of hydrogel for agricultural and forestry use in saline conditions

This research tested the hypothesis that interaction between time and salinity reduces water absorption potential of a hydrogel – Poly (Acrylamide-co-Potassium Acrylate) influence degradation residual acrylamide monomer. The experimental design was completely randomized split-plot with four replications. treatments were periods (30, 60, 90 120 days) levels hydrating solution (distilled = 0.003, 0.5; 1.5; 3.0 6.0 dS m?1). Swelling, composition, monomer concentration evaluated. showed lowest (8.1 g g?1) in saline 4.20 m?1 after days. C/N ratio increased by up to 47% an EC 4.4 at Additionally, there observed shift wavelength methylene, amide, acrylate bands, indicates degradation. Residual <0.5 mg g?1 (safe for agricultural use). After days 85% degraded. About potential, results suggest under semi-arid conditions durability forestry crops applications may be impaired solution.
