Water scarcity and land infertility pose significant challenges to agricultural development, particularly in arid semiarid regions. Improving soil-water-retention capacity fertilizer utilization efficiency through the application of soil additives has become a pivotal approach practices. Hydrogels exhibit exceptional water absorption retention capabilities, making them extensively utilized fields agriculture, forestry, desert control. Currently, most reviews primarily focus on raw materials, classification, synthesis methods, prospects hydrogels, with limited attention given strategies for enhancing water-retention performance, mechanisms underlying absorption, environmental risks. This review covers commonly used cross-linking methods hydrogel structure-activity relationship between hydrogels as well fertilizer. Additionally, thorough analysis ecological benefits risks associated is presented. Finally, future are delineated from perspectives material design engineering applications.

Superabsorbent materials (SAMs), featuring a three-dimensional (3D) hydrophilic polymer network, can absorb and retain water up to thousands of times their own weight, even under pressure. This makes them indispensable in various fields, including hygiene products agriculture. The absorption capacity SAMs is influenced by the presence groups swellable network structure. To optimize performance, one must adjust types concentrations functional groups. Additionally, changes density regularity are necessary. Significant performance improvements limited inherent challenges modifying chains or networks. enhance researchers focus on manipulating components structure network. Effective retention requires fully expand while maintaining its strength. Incorporating nanoparticles, especially one-dimensional (1D) nanoclays, minimizes chain entanglement prevents collapse during drying. approach effectively addresses above challenges. Upon swelling, these nanoparticles improve hydrogen bonding within significantly boosting SAMs. Nanoclays abundant natural silicates found nanostructures like nanorods, nanofibers, nanotubes. These nanoclays contain reactive silanol that form strong bonds with chains. aids formation reduces costs. Advances synthesis structural control have facilitated development versatile 1D nanoclay-based paper reviews structure, characteristics, applications such proposes future research directions aimed at developing higher-performance clay-based

The current use of fertilizers is inefficient and not sustainable. majority the fertilizer applied does reach targeted crop but lost in water bodies into atmosphere, with harmful impact on environment. To enhance efficiency sustainability agricultural practices, it essential to address two complementary challenges. First, nutrient delivery methods must be refined maximize plant uptake. Second, recovery nutrients from wastewater other waste streams should improved recycling nitrogen phosphorous reduce environmental pollution. Biodegradable polymers hold great promise for development technological solutions toward more sustainable practices. This review covers application biodegradable both aspects cycle: plants through slow- controlled-release fertilizers, using membrane separation, adsorbent composites, coagulants/flocculants. most promising materials are highlighted approaches, identifying research gaps discussing potential future directions this highly significant field.

Abstract Sustainable agriculture aims to provide food needs while improving soil health and protecting it from degradation contamination excessive chemical fertilizer use. Sandy-textured soils have low fertility water-holding capacity. This study assessed the integrated impact of super absorbent polymers (SAPs) biofertilizer application on characteristics wheat growth parameters in sandy loam soil. Two included Barbary plant G3 (P1) Aqua Gool polymer (P2), four microbial inoculations ( Trichoderma harzianum (T), Actinomycetes Streptomyces rochei atrovirens) (AC1 AC2), Bacillus subtilis (B)) as biofertilizers were used our pot experiment. The SAPs applied at a level 0.2% (w/w), form cell suspensions (50 ml per pot) addition treating seed with these during cultivation. Wheat plants irrigated every 8 days field capacity level. Amending microbes either individually or combination significantly reduced pH EC, increased organic matter level, availability macro- micronutrients metrics, including shoot length, tiller number, biomass accumulation, leaf area, grain yield, exhibited considerable enhancements relative control treatment. interaction between P1 atrovirens (AC2) showed highest performance almost studied parameters. offers promising eco-friendly method for enhancing yield.

Acute shortage of water resources and high unproductive losses are the key problems irrigated agriculture in arid regions. One possible solutions is to optimize soil retention using natural synthetic polymer absorbers. Our approach uses HYDRUS-1D design placement organic absorbents such as peat composite hydrogels profile form water-storing capillary barriers. Field testing used a balance greenhouse experiment with cultivation butternut squash (butternut (Cucurbita moschata (Duchesne, 1786)) under sprinkler irrigation measurement moisture lysimetric outflow. In addition, biodegradation rate was studied at surface depth 20 cm. Organic barriers reduced by 40–70%, retaining topsoil increasing evapotranspiration 70–130% corresponding increase plant biomass fruit yield. The deepening modifiers calculated not only allowed form, but also prevented their biodegradation. best results retention, growth yield according “dose-effect” criterion were obtained for superabsorbent filling an acrylic matrix. study showed good compliance between HYDRUS actual efficiency innovative technology absorbents.

Superabsorbent polymers (SAPs) are effective soil amendments that can control erosion by improving quality. However, many commercial SAPs face challenges including limited biodegradability, high costs, and adverse effects on hydrological properties, which lead to increased water loss. This study examined the potential of lower dosages biodegradable improve properties “Shimajiri-maji” (clay) soil. Three concentrations Fasal Amrit polymer (EFP) (P1: 0, P2: 3 g m−2, P3: 6 m−2) were evaluated under three simulated rainfall intensities (I1: 35; I2: 70 I3: 110 mm h−1) two gradients (7.5%, 15%) during consecutive storms. The time generate runoff, infiltration, loss, storage (WS) quantified over one hour. results show runoff generation was delayed in EFP-treated soils compared control. Both treatments enhanced infiltration (P2 > P3 P1) reduced loss < P1). Higher EFP rates improved at surface depths (P3 P2 exhibited interrill erodibility, suggesting greater resistance also significantly soil’s physical (bulk density, porosity, organic matter, aggregate stability). EFPs diminish as plots stability than It concluded low mitigate erosion. Further investigations needed optimize for different types.
