“…Polysaccharides are one of the most important classes of organic matter in soils as they can enhance multiscaled water interactions, enhance the cohesion of granulated matter, serve as nutrients for the microbiome, and eventually act as a long-term sink of carbon . In recent years, the use of natural polymers as soil amendments has been extensively studied, showcasing their potential benefits. ,− Gums have been the most explored carbohydrate polymers to improve the cohesive properties of soils that are otherwise unfit for agriculture or highly prone to erosion . While they present excellent properties, there are alternative sources that do not contribute to the food supply chain, − such as basic and advanced cellulosics, which may bring the largest benefits as amendments due to their wider spread availability and inherent properties.…”

“…Overall, we expect the study to provide deeper insights into the potential of cellulosics to improve the mechanics and humidity response of granular inorganic materials, such as sandy soils. This research explores aspects of nanocellulose applications in this new contextincluding impact of humidity, pH effects, and fracture regimesin a field that has seen substantial attention and growth in recent times. ,− …”

Soil quality is one of the main limiting factor in the development of the food sector in arid areas, mainly due to its poor mechanics and lack of water retention. Soil's organic carbon is nearly absent in arid soils, though it is important for water and nutrient transport, to soil mechanics, to prevent erosion, and as a long-term carbon sink. In this study, we evaluate the potential benefits that are brought to inert sand by the incorporation of a range of, mainly, cellulosic networks in their polymeric or structured (fiber) forms, analogously to those found in healthy soils. We explore the impact of a wide range of nonfood polysaccharide-based amendments, including pulp fibers, nanocellulose, cellulose derivatives, and other readily available polysaccharide structures derived from arthropods (chitosan) or fruit peels (pectin) residues. A practical methodology is presented to form sand−polymer composites, which are evaluated for their soil mechanics as a function of humidity and the dynamics of their response to water. The mechanics are correlated to the network of polymers formed within the pores of the sandy soil, as observed by electron microscopy. The response to water is correlated to both the features of the network and the individual polysaccharides' physicochemical features. We expect this work to provide a rapid and reproducible methodology to benchmark sustainable organic amendments for arid soils.

“…Biopolymers derived from organics [29] emerged as a viable strategy as they modify soil structure, texture, or chemistry, enhancing cohesion, angle of internal friction, capillarity, permeability, elasticity, compressibility, and shear strength. However, they are not as effective as granular additives such as Ferrochromium Slag [30].…”

The geotechnical properties of clay soil and its mixtures with different proportions (0.75%, 0.85%, 1%, and 1.15%) of Agar Gum biopolymer and Ferrochromium Slag (0.25%, 0.50%, 0.75%, and 1%), having various curing times and freeze-thaw cycles, were studied through a series of soil mechanical tests to investigate possibilities to improve its undesired/problematic plasticity, compaction, and shear strength characteristics. The results revealed that treatment with an optimal ratio of 1% Agar Gum and 1% Ferrochromium Slag alone, as well as together with, improved the geotechnical properties of the clay soil considerably. Both the unconfined and shear strength properties, along with the cohesion and internal friction angle, increased as much as 47 to 173%, depending on the curing time. The higher the curing time, the higher the shear strength, cohesion, and internal friction angle are up to 21 days. Deteriorating the soil structure and/or fabric, freeze-thaw cycles, however, seem to have an adverse effect on the strength. The higher the freeze-thaw cycle, the lower the shear strength, cohesion, and internal friction angle. Also, some improvements in the plasticity and compaction properties were determined, and environmental concerns regarding Ferrochromium Slag usage have been addressed.
