A novel bio-based superabsorbent polymer (CMAKG-SAP) enhances soil water retention and offers controlled nitrogen release. This sustainable material shows great promise for improving crop yields in arid regions.

Area Of Science

  • Agricultural Science
  • Polymer Chemistry
  • Environmental Science

Background

  • Arid and semi-arid regions face significant crop challenges due to water deficits and nutrient loss.
  • Conventional agricultural practices struggle to mitigate soil water leakage and fertilizer deficiency.

Purpose Of The Study

  • To synthesize and characterize a bio-based superabsorbent polymer (CMAKG-SAP) for agricultural applications.
  • To evaluate the water absorption, retention, and controlled-release properties of CMAKG-SAP in soil.

Main Methods

  • Graft copolymerization was used to synthesize CMAKG-SAP.
  • Morphological, thermal, water absorption, and soil tests were conducted.
  • Nitrogen release and biodegradation were analyzed.

Main Results

  • CMAKG-SAP exhibited a porous structure, high thermal stability, and a maximum water absorption capacity of 497.32 g/g.
  • The polymer maintained 81.44% water absorption after five cycles and improved soil water retention.
  • Controlled nitrogen release and biodegradability were observed, with enhanced fruit quality at 50% application.

Conclusions

  • CMAKG-SAP effectively enhances soil water holding capacity and provides controlled nutrient release.
  • The bio-based polymer shows significant potential for sustainable agriculture in water-scarce regions.
  • CMAKG-SAP can promote water-saving cultivation and improve crop quality.

Superplasticizers 01:30

296

Superplasticizers are advanced admixtures that enhance the workability of concrete by lowering the water content without compromising the strength of the material. These substances are highly effective water reducers, improving concrete flow, making it easier to work with, and enabling concrete to reach inaccessible areas or densely reinforced sections without mechanical vibration. The key components in superplasticizers are either sulfonated melamine or naphthalene formaldehyde condensates,...

Anionic Chain-Growth Polymerization: Overview 01:20

2.5K

The polymerization process that involves carbanion as an intermediate is called anionic polymerization. It is also a type of addition or chain-growth polymerization. Anionic polymerization gets initiated by a strong nucleophile such as an organolithium or a Grignard reagent. The most commonly used initiator for anionic polymerization is butyl lithium. Monomers involved in anionic polymerization must possess a vinyl group bonded to one or two electron-withdrawing groups. For instance,...

Molecular Weight of Step-Growth Polymers 01:08

2.7K

Step growth polymerization involves bi or multifunctional monomers. Bifunctional monomers react to form linear step growth polymers, whereas multifunctional monomers react to form non-linear or branched polymers.
As the step-growth polymerization involves step-wise condensation of monomers, the molecular weight also builds up eventually. Consequently, high molecular weight polymers are obtained at the late stages of the polymerization, where 99% of monomers have been consumed.
The extent of the...
