The state of water in KCl hydrated powder, in KCl/AM1/H2O composite system and with hydrophobic organic compounds added has been studied in the air environment by low-temperature NMR spectroscopy. The presence of hydrophobic nanoparticles in composite system consisting of KCl hydrated salt powder and AM1-300 hydrophobic nanosilica has been established to significantly increase water binding to the surface. As a result, water retention in the composite is significantly higher than in the powder fertilizers. An additional increase in interfacial water binding has been reported for the case when KCl/AM1/H2O composite system contacts with hydrophobic substance imitating hydrophobic areas of seed surface. It is likely explained by an increase in free energy as a result of water cluster split in nanoscale systems with hydrophobic and hydrophilic components.

Keywords: composite system, mineral fertilizers, NMR spectroscopy, seeds, strongly- and weakly bound water, water clusters
