“…4, 13, 14, 29). Compared to the previous soil−water properties and characteristics, infiltration and K sat had the greatest variability in response to SAP application ; of the papers reviewed there was both an increase and decrease found for infiltration and K sat response to SAP application Using a sandy loam soil with 3 g dm −3 (0.2% BM) SAP application, infiltration decreased from 7 to 4.4 cm h −1 (Abrisham et al., 2018); for a silt loam soil, runoff was reduced by 24.6, 41.5, 46.5, 50.7% relative to the control (284 L of runoff) for SAP applications of 0.25, 0.5, 0.75, 1.0, and 2.0% BM, respectively, applied at the 5‐cm depth (Cao et al., 2017).

“…1, 3, 18). With no SAP application, PAW was 3.6% for a sandy loam soil, and with 1 g dm −3 (0.07% BM) and 3 g dm −3 (0.2% BM) PAW increased to 6.1 and 8.8%, respectively (Abrisham et al., 2018). When applied to dune sand at rates of 0.3, 0.6, and 1% SAP/soil, PAW increased from the control (5 g kg −1 ) by 560, 200, 270 g kg −1 , respectively (Banedjschafie & Durner, 2015).…”

“…Just as SAPs can alter soil pH and EC, they can change CEC. For example, SAP application of 3 g dm −3 (0.2% BM) to a sandy loam soil increased CEC from 6.2 to 8.2 cmol c kg −1 but no change was observed at an application rate of 1 g dm −3 (0.07% BM) (Abrisham et al., 2018). Similar to changes in soil pH and EC, changes in CEC are associated with the composition of SAPs.…”

“…For example, in a greenhouse study on a sandy clay loam soil, 0.3% by mass (BM) SAP application significantly decreased BD from 1.27 to 1.17 g cm −3 after undergoing four wetting−drying cycles (Bai et al., 2010). Bulk density of a sandy loam was shown to significantly decrease with 3 g dm −3 (0.2% BM) SAP application from 1.56 to 1.45 g cm −3 , but the authors recommended the application rate of 1 g dm −3 (0.07% BM) because it was statistically similar to the higher rate (Abrisham et al., 2018). Furthermore, BD decreased from 1.72 and 1.71 g cm −3 to 1.63 and 1.56 g cm −3 , respectively, for two consecutive years after 90 kg ha −1 application of 0.1% SAP/soil mixture at the 0‐ to 30‐cm depth of a sandy loam soil (Hou et al., 2017).…”

“…The primary use of SAPs has been their incorporation into soil to increase water retention and consequently improve plant growth (Dehkordi et al., 2017; Egrinya Eneji, Islam, An, & Amalu, 2013; Montesano, Parente, Santamaria, Sannino, & Serio, 2015). The nature of SAPs to swell has been shown to reduce BD (Abrisham et al., 2018; Bai et al., 2010; Hou et al., 2017) and increase permeability (Han et al., 2010). However, the influence of SAP on soil evaporation has had mixed results (Al Jabri, Rahman, & Ibrahim, 2015; El‐Asmar, Jaafar, Bashour, Farran, & Saoud, 2017).…”

Superabsorbent polymers (SAPs) are materials that can absorb significant amounts of water relative to their mass. The nature and properties of SAPs make them a widely utilized material across many disciplines. A systematic review was conducted to examine the use of SAPs within agriculture and environmental science. The method of application, rate, and the subsequent impact on soil properties were determined. Superabsorbent polymers can be used to improve and prolong soil water holding capacity, decrease drought stress, and increase time between irrigation events. There are results indicating SAPs can reduce compaction. Yield and plant growth characteristics were improved for all but one of the reviewed studies. While SAPs show potential as a tool, their economic feasibility on large‐scale and long‐term projects should be evaluated.

Carboxylated nanocellulose superabsorbent polymers (SAP) can be used to increase soil water retention in agriculture. The benefits investigated are influenced by the superabsorbent structure, composition and application rate.In this study, TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl)-oxidised nanocellulose superabsorbents were prepared using three different drying techniques: freeze-dried, and oven-dried at low and high temperatures. The swelling capacity in soil water extracts was measured and compared to deionised water. Soil was amended with different application rates of these superabsorbents to evaluate the effects on water retention, microbial community and their biodegradation.The absorption performance of nanocellulose superabsorbents is affected by the concentration and type of salts in the soil water extracts. Oven-dried at 50 °C SAP presents the highest ionic sensitivity attributed to its large number of accessible carboxylate groups. The water retention of the soil treatments increases with increasing application rate. Soil treated with the freeze-dried superabsorbent shows the highest water retention, whereas those amended with the 50°C oven-dried SAP remain moist the longest. The biodegradation rate of these materials depends on the application rate and nutrient availability. Carboxylated nanocellulose superabsorbents emerge as highperformance biodegradable materials for agricultural use, able to replace the current nonbiodegradable petrochemical-based superabsorbents. INTRODUCTIONWater is critical for agricultural production and food security. Irrigated agriculture uses about 70% of the water available for human consumption worldwide and accounts for 59% of the total fresh water in Australia (Organisation for Economic Co-operation and Development; Department of Agriculture 2020). Water availability has been impacted by climate change, drought and water shortage; its decrease has affected world agricultural development in recent years. According to Müller C. (2010), agricultural yields will decline between 2 -15% over the next 30 years due to climate change. Hence, the efficient use of water resources is crucial for the long-term sustainability of the agricultural industry.One strategy to optimise water retention in soils and hence making it more available to crops, is the use of superabsorbent polymers (SAPs) (Zohuriaan-Mehr et al. 2008). SAPs are three-dimensional (3D) networks of linear or branched hydrophilic polymers physically or chemically cross-linked (Guilherme et al. 2015). SAPs can absorb and hold water at hundreds of times their own weight and remain stable in their swollen state (Ahmed 2015;Ghorbani et al. 2019;Shen et al. 2016;Gross JR 1990). They have been extensively used in many applications including biomedicine (Curvello et al. 2019), food and beverages (Shewan and Stokes 2013), personal care and hygiene products (Bashari et al. 2018). In the agricultural and horticultural industries, SAPs have a range of applications which includes seed coatings, seed additives and root dips (Zoh...

The application of copolymer hydrogels based on acrylamide (AAm) and acrylic acid (AA) in sub‐Saharan soils can increase the quantity of water retained by the soil and improve plant establishment and growth. The aim of this work was to synthesize and characterize a copolymer based on acrylamide and acrylic acid and to evaluate its swelling capacity with different physicochemical parameters. This study also aimed to investigate the effect of metallic cations on the swelling capacity of the copolymer and to assess the improvement in water retention in sandy soils. The copolymer material was prepared by free‐radical polymerization in aqueous solution at a temperature of 60°C and characterized by Fourier transform infrared (FTIR) and x‐ray diffraction (XRD), and its average molecular weight was estimated from intrinsic viscosity measurements. The swelling capacity was evaluated with different physicochemical parameters, and the effect of metallic cations on the swelling capacity was investigated. Water retention in two sandy soils was also evaluated. The copolymer material containing 50% AAm and 50% AA can retain more than 8100% of water. The swelling ratio increased with increasing temperature, with a maximum swelling ratio at 65°C. The presence of metallic cations reduced the maximum swelling ratio of the copolymer material as the cation concentration increased. The copolymer material at 1% in a composition with the soil showed an improvement in the water retention of 12.2% and 7.9% for soil A and 7.9% for soil B. Soil air volume is improved by 19% for both soils. This study shows that the copolymer material has a high swelling ratio and can improve water retention in sandy soils. The copolymer can be used in agriculture to protect and improve plant growth and yield.Highlights Synthesis and characterization of a copolymer based on acrylamide and acrylic acid.
