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, hydrogels are the most promising materials in polymer and materials science. Due to their soft and tissue-like properties and high water content, hydrogels have a wide range of applications, such as in tissue engineering and wound dressings.
In recent years, with the development of hydrogels, particularly superabsorbent hydrogels, a new type of fertilizer has emerged, namely water-retaining slow/controlled-release fertilizers.
Globally, agricultural water shortage are becoming increasingly severe. Climate change and population growth have led to water resource shortages, which have become a key factor limiting agricultural development. According to the United Nations' 2023 World Water Development Report, approximately 2 billion people worldwide face drinking water security issues, with agricultural water use accounting for 70% of global water extraction. In response to this challenge, the advent of agricultural water retaining agents has not only effectively improved soil moisture utilization efficiency but also reduced water waste, playing a crucial role in the sustainable development of agriculture.
As water resources become increasingly scarce, hydrogel materials are becoming more important as soil conditioners in the agricultural sector, especially in areas with limited water supply.
Avocado, a nutrient-rich and uniquely flavored fruit, requires specific cultivation techniques to achieve high-quality yields.
With the continuous progress of agricultural science and technology, the research and development of agriculture super absorbent polymer materials is showing new trends and innovations.
Super absorbent polymers (SAPs) are being used in a wide range of applications in modern industry, including agriculture, medicine, hygiene and personal care.
In recent years, secondary soil salinization has become a significant global environmental concern, stemming from both natural processes and human activities.
Sodium polyacrylate, a highly functional polymer material, has found its way into various industries, playing a pivotal role in enhancing production processes and product quality. Its unique properties make it an indispensable additive in numerous applications.
The utilization of super absorbent polymer has revolutionized agricultural practices, particularly in terms of soil management.
Protecting the environment, plant, animal, and human health using natural strategies is a key objective for developed nations.
