Since the 21st century, with the strengthening of climate change, afforestation, drought resistance, and water-saving measures, the research and application of soil water-retaining hydrogel have played an important role in soil improvement, urban greening and barren slope afforestation, water and soil conservation, slope management, reclamation of abandoned mining areas, and the development of new types of water-retaining fertilizers.


Currently, soil water-retaining hydrogel can be classified based on their raw materials and synthesis technology into organic monomer polymerization (e.g., sodium polyacrylate), starch polymerization (e.g., starch grafted sodiumpolyacrylate), organic-inorganic composites (e.g., attapulgite/sodium polyacrylate), and organic monomers compounded with functional components (e.g., humic acid type water-retaining agents).


Different types of water-retaining hydrogel show significant differences in water retention characteristics, especially in terms of the reduced water absorption rates in deionized water, tap water (conductivity 0.8~1.0 s/cm), and various ion solutions, as well as repeated water absorption capabilities. These differences significantly impact their application scope. Organic monomer polymerized water-retaining agents (polyacrylates) have the highest water absorption multiples in deionized water and show water retention performance lasting over 10 days under natural conditions. Organic-inorganic composite water-retaining agents (attapulgite/sodium polyacrylate) and water-retaining agents compounded with functional components (humic acid type) display notable repeated water absorption and resistance to divalent (Ca2+) and trivalent (Fe3+) ions, making them suitable for soil improvement in saline-alkali lands and abandoned lands.


Among them, sodium polyacrylate is a super absorbent polymer, with the chemical formula (C3H3NaO2)n, capable of absorbing hundreds of times its own weight in water. This characteristic and its swelling behavior during the absorption process have been applied in various fields, including flood control measures and water-retaining soil conditioners. In the continuously developing fields of agriculture and horticulture, efficient water resource utilization and soil health are crucial for maximizing yields and ensuring sustainability.


Enhancing soil moisture retention


One of the most notable features of super absorbent sodium polyacrylate is its excellent water absorption capability. By using sodium polyacrylate to increase the number of stable water-holding aggregates in the soil, improve soil permeability, reduce surface runoff, enhance soil erosion resistance, and achieve good water and soil conservation effects, nutrient retention, and increased yields. The application of sodium polyacrylate can reduce the frequency of irrigation, thereby saving water resources and lowering labor costs. Whether for commercial farmers or home gardeners, the benefits of incorporating this material into soil management practices are evident.


Improving soil structure and health


Super absorbent sodium polyacrylate not only retains moisture but also improves soil structure and health. Overuse of fertilizers and chemical pollution can damage soil structure, causing issues like soil compaction and heavy texture. Adding sodium polyacrylate can improve soil structure by increasing soil aeration and seepage rates, thereby protecting the environment while increasing high-yield, high-quality crops. This is due to its polymer nature, which increases soil aggregates, absorbs and swells with water in the soil, binds dispersed soil particles into larger clumps, reduces soil bulk density, increases porosity, and regulates water, air, and heat conditions in the soil, benefiting crop growth. Improved soil structure ensures plants have easier access to nutrients, promoting better growth and higher yields. Sodium polyacrylate suppliers like SOCO understand the importance of soil health, providing products designed to optimize these benefits.


Landscape and Horticuluture maintenance


Maintaining lush landscapes or gardens can be challenging, especially in areas with limited water resources. By utilizing super absorbent sodium polyacrylate, you can create beautiful and sustainable landscapes and gardens. Sodium polyacrylate reduces the need for frequent irrigation, making horticulture maintenance more effortless and environmentally friendly. As one of the sodium polyacrylate suppliers, SOCO offers a wider range of possibilities, not only familiar with various soils and crops but also providing comprehensive guidance and innovative alternatives like potassium-based polyacrylate and new water-retaining fertilizers mixed with other fertilizers.
