Abstract
A study was conducted in lab for synthesizing and characterizing the behavior of the nanoclay-polymer composites (NCPCs). Furthermore, greenhouse experiments carried out to investigate the effects of NCPCs application on crop yield, nutrient uptake, soil nitrogen availability and N2O emission. Wheat flour (WF), sodium alginate (Na-Alg) and acrylic acid (AA)+ acrylamide (Am) (AA+Am) NCPCs were synthesized via free radical polymerization and characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), SEM-energy dispersive X-ray (SEM-EDX) and transmission electron microscopy (TEM). At lower dose NCPCs, resulted in significantly equal grain yield in rice and wheat with 100% urea treatment with reduced amount of N2O emissions. Yield-scaled N2O emissions of rice and wheat under T9 [NCPC (AA+AM+Clay) (75% N of RDF) + PK (full dose)] treatment was respectively 19.8 and 25.5% lower than urea treatment. These findings demonstrate that there is a great potential to increase crop yields with lower N2O emissions through use of innovative fertilizer technique in India.
