Drought is one of the most important stress factors limiting the seed industry and crop production. Present study was undertaken to create novel drought-resistant pelleted seeds using the combined materials with superabsorbent polymer, poly(2-acrylamide-2-methyl propane sulfonic acid) (PAMPS) hydrogel, and drought resistance agent, salicylic acid (SA). The optimized PAMPS hydrogel was obtained ...

We study rain water infiltration and drainage in a dry model sandy soil with superabsorbent hydrogel particle additives by measuring the mass of retained water for non-ponding rainfall using a self-built 3D laboratory set-up. In the pure model sandy soil, the retained water curve measurements indicate that instead of a stable horizontal wetting front that grows downward uniformly, a narrow fing...

conventional processes of food dewatering, such as thermal, have undesirable and destruction effects on vitamins, aromatic compounds and pigments. in addition, they are accompanied with some technological complications and energy consumption. thus, food concentration processes are directed to non-thermal techniques or methods with reduced heat effects. superabsorbents are highly hydrophilic pol...

The deficiency of water sources and the environmental disposal large amounts biomass waste (orange peels) produces economic problems, though its conversion into biochar by a pyrolysis procedure might be used to improve soil productivity. In current study, we investigated performance superabsorbent composite grafted on CMC as low-cost, alternative, biodegradable terpolymer (IPNCB) for retention ...

The use of some novel and efficient crop nutrient-based superabsorbent hydrogel nanocomposites (SHNCs), is currently becoming increasingly important to improve the crop yield and productivity, due to their water retention properties. In the present study a poly(Acrylamide-co-acrylic acid)/AlZnFe2O4 superabsorbent hydrogel nanocomposite was synthesized and its physical properties characterized u...
