“…With specific regard to agricultural applications and the need to control the swollen NHA degradation rate in the soil, the use of binary and multicomponent super absorbents is gaining attention (Messa & Faez, 2020). Multicomponent NHAs are shown to slow down the nitrogen release, improve soil moisture management and partially alleviate environmental hazards related to the use of pure synthetic SAPs (Li & Lin, 2021; Zhou et al, 2019). The deployment of NHAs in agriculture is hindered by the poor understanding of how their structure controls the water swelling/nutrient release behaviour, especially under confined conditions under a layer of soil.…”

There is a pressing need for advanced fertilizer application technologies that enhance crop yields, maintain soil health and reduce the environmental impact from agriculture. Here, we report on the optimization of nitrogen release profiles of urea‐loaded polysaccharide (starch) superabsorbent carriers, employing analytical techniques including UV–VIS, FTIR, EDX, SEM and GC‐FID for structural and phospholipid fatty acids PLFA analyses. We fitted existing kinetic models to the uptake and release profiles, providing a link between nitrogen release kinetics and carrier structural variables. The inclusion of zeolite microparticles in the starch‐based carriers accelerated the rate of nitrogen release and increasing the maximum amount released. Field tests of the technology on maize crops demonstrated improved plant parameters and enhanced the soil microbial population. These findings highlight the promise of urea‐loaded natural superabsorbent carriers as a sustainable alternative to core‐shell CRF fertilizers and urease inhibitors.

Superabsorbent polymers have important applications in many elds, but insu ciency of water/salt absorbency, water retention, and swelling rate limit its application development. Herein, we fabricated HEC-g-P (AA-co-AMPS)/laterite by aqueous solution polymerization, the structure and morphology of the superabsorbent polymer were characterized by FTIR, SEM and TG/DTG. The optimal water absorbency of the superabsorbent polymer were 1294 g/g, 177 g/g, and 119 g/g in distilled water, tap water, and 0.9 wt% NaCl solution, respectively. The superabsorbent polymer had good water retention and re-swelling properties at different temperatures, and fast water absorption rate, and reached swelling equilibrium at 5 min. The swelling mechanism of the superabsorbent polymer was explained by the pseudo-second-order swelling kinetics model and Ritger-Peppas model. The effect of the amount of hydrogel on the water evaporation rate in soil was studied, and it had a good effect.
