To determine a mechanism of stimulating influence of protective-stimulating compositions (PSC) on the germination process of wheat seeds, hydration of composites prepared with methylsilica AM-1-300 and a mixture of nitrogen, phosphate and potash fertilizers is studied (composition is 1:1.5 respectively). As revealed, a significant portion of adsorbed water transforms into a weakly associated state, in which water molecules do not form the continuous network of hydrogen bonds at the interfaces between the hydrated composite particles and a weakly polar organic medium. The amount of such water is comparable to the weight of a solid phase. As assumed, the stimulating effect is caused by acceleration of the mass-transfer processes within the layer of weakly associated water, electrostatic retention of composite particles in a vicinity of shoot buds, and complete utilization of the fertilizers from PSC by the plant.
