Summary: This study evaluated the effects of biochar and deficit irrigation on sweet corn in West Texas. The results showed that 70% crop evapotranspiration can be used as an alternative to full irrigation, with minimal yield loss. Hardwood biochar amendments improved vegetative biomass but had a minor effect on yield.

Summary: This study focuses on the effectiveness of using core-shell super absorbent polymers (SAPs) as triggerable materials in coating binders for plastic recycling processes. The incorporation of SAPs into coatings led to the debonding of coatings from substrates under steam treatment, showing potential for plastic recycling applications in industries. The trigger mechanism of the core-shell hydrophilic SAPs relies on their ability to absorb water and break the inorganic shell under the influence of steam, reducing the attachment between layers and enabling detachment.

Summary: We propose a new approach to model the swelling, drying, and elastic behavior of hydrogels, combining linear-elastic theory with nonlinearities resulted from large swelling strains. We present a constitutive model for the Cauchy stress tensor, linearizing small deviatoric strains while considering a nonlinear relation between stress and isotropic strains. By coupling interstitial water flow with elastic response, the dynamics of swelling and drying are described. This approach allows for a complete description of gel behavior using only three macroscopic polymer-fraction-dependent parameters, which can be determined experimentally.

Summary: In this work, a novel potassium ion-based SAP (K-SAP) with significantly enhanced water uptake was achieved by creating a high elastic framework for SAP using nanoparticles as physical cross-linker. The water-absorbing capacity of K-SAP reached 3600 g/g in distilled water, demonstrating its potential for various applications including waste-water treatment and hygienic products.

Summary: The experiments showed that both agricultural gamma-PGA and gamma-PGA SAP could reduce soil water infiltration in sandy loam soil. The addition of gamma-PGA had no significant impact on total available water in the soil, while the addition of gamma-PGA SAP greatly increased the total available water content. The study provides valuable information for the use of these materials in agricultural applications.

Summary: Based on the simulation and analysis of rainfall-runoff processes in the karst distribution region of South China, this study reveals the significant impacts of watershed lagged effects on the rainfall-runoff process and the differences in lag response among different time scales. The study also demonstrates a significant negative correlation between the watershed lagged intensity and frequency. These findings provide a scientific basis for water resources utilization, drought resistance, and disaster relief in karst areas.

Summary: The study investigated the interactions of acrylic acid-based super absorbent polymers (SAPs) with water and the hydrogen bonding of water within its three-dimensional network using Raman spectroscopy. It compared the changes in hydrogen bonding of water with those of water in SAPs and elucidated their temperature-dependent variations. The Raman spectra revealed differences in CH and COO- peak shifts of SAPs with the addition of water.

Summary: The study found that reducing drain depth significantly decreased drain outflow and water input, while increasing irrigation efficiency, seed yield, and irrigation water use efficiency. Reducing drain depth to below 40 cm is recommended to maximize water saving, though it may lead to potential salinity buildup. Careful water and soil management practices, such as periodic leaching, are essential when decreasing drain depth to prevent adverse effects on crop yield and soil quality.

Summary: Breeding drought-tolerant wheat is an effective way to mitigate drought effects. This study identified potentially drought-tolerant wheat genotypes through evaluating a large collection of genotypes under water deficit and well-watered conditions in Egypt. The results showed significant effects of environments, water stress, and genotypes on plant height, days to flowering, and grain yield. Under water deficit, earlier and shorter wheat genotypes tended to produce higher grain yield, while late flowering and taller genotypes performed better under well-watered conditions.

Summary: Climate change models predict an increase in rainfall variability, leading to floods and drought events, intensifying the necessity for reservoirs. However, up to 50% of reservoirs' capacity is lost by evaporation, affecting water availability and stability. Various barriers have been developed to inhibit evaporation, but their efficiency, applicability, and environmental consequences are still under debate.

Summary: The study found that using white floating covers can significantly reduce water reservoir evaporation in two different locations, with white balls having the greatest effect. When considering water ecology, white balls or 91% coverage white foam sheets are recommended for use. Further research in real reservoirs is needed to investigate the durability and stability of the used covers.

Summary: Wheat production is being impacted by wheat rusts, elevated ozone, and carbon dioxide simultaneously, but their interactions are not well understood. This study shows that near-ambient ozone conditions are conducive to stem rust in wheat, contradicting the current consensus. The findings suggest that sub-symptomatic ozone stress may enhance rust diseases in wheat-growing regions.
