use of polymers and biopolymers for water retaining and soil stabilization in arid and semiarid regions

Use of polymers and biopolymers for water retaining and soil stabilization in arid and semiarid regions

The results showed that the polymer composites (10 mg/L Polyacrylamide and 0.5g / L Cellulose) in soil could improve better soil physical properties and augment 60 % water retention at arid soils compared with application of any other polymer at the same concentration.

long©term water retention increases in degraded soils amended with cross©linked polyacrylamide

Long©term water retention increases in degraded soils amended with cross©linked polyacrylamide

Soil water retention and plant available water (PAW, g water g ?1 dry soil ?1) were measured in soil samples collected in spring for seven of the nine years. Across all years, the 0.5% XPAM produced the greatest PAW (0.318) and the PAW of other treatments followed in the order: 0.5% XPAM > 0.25% XPAM > Topsoil > 0.5% XPAA > 0.25% XPAA = control (0.224).

superabsorbent polymers used for agricultural water retention

Superabsorbent polymers used for agricultural water retention

Introduction Water plays a critical role in agricultural production. However, water shortages and droughts have caused soil desertification and salinization, which also challenge the sustainable development of agriculture as well as food security. Therefore, improving the utilization efficiency of water is of great importance in agriculture [ 1 ].

Effects of ionized brackish water and polyacrylamide application on infiltration characteristics and improving water retention and reducing soil

There is an urgent need for brackish groundwater-based irrigation methods to be developed for saline soils that are effective, economically advantageous, and environmentally friendly. The use of both ionized brackish water and polyacrylamide (PAM) might provide such a method. The long-term use of brackish water irrigation can lead to the secondary salinization of soil and, as a consequence

Abstract. Understanding the effects of soil intrinsic properties and extrinsic conditions on aggregate stability is essential for the development of effective soil and water conservation practices. Our objective was to evaluate the combined role of soil texture, aggregate size and application of a stabilizing agent on aggregate and structure

spotlight on the life cycle of acrylamide-based polymers supporting reductions in environmental footprint: review and recent advances

Spotlight on the Life Cycle of Acrylamide-Based Polymers Supporting Reductions in Environmental Footprint: Review and Recent Advances

PAMs have been used for more than three decades as soil conditioning or water retention agents []. These two areas are distinguished by the nature of the polymer used. Indeed, in soil conditioning [ 96 ], the polymer has linear structure and is assimilated as a flocculant, whereas the water retention polymer is a crosslinked anionic network with superabsorbent capabilities [ 97 ].
