A polymer-based superabsorbent (NSP) is characterised by nitrogen content, equilibrium water absorbency (WA) .Field application of NSP @ 10 kg ha-1 with one (01) irrigation at CRI stage of wheat can save two (02) irrigation requirement. Superabsorbent polymer (@ 10 kg ha-1) is economically viable option for chickpea, lentil and mustard.
Specific advantages
NSP is unique product where water-nitrogen synergistic interaction has been employed in rhizosphere. It can be applied irrespective of soil reaction (acidic, neutral and alkaline). It gradually releases moisture (desorption curve) across suction range (1-15 bar). It stimulates microbial processes in the rhizosphere in terms of increase in soil dehydrogenase activity. NSP improves soil physical property (aggregation, hydraulic conductivity and available moisture content).
