The hydratation of tannin and its composite based on tannin and methylsilica AM1 is studied by low-temperature 1H NMR spectroscopy. It is shown that the amount of weakly associated water in the composite system is greatly increased, which can serve as a sensitizer of the nutrients mass transfer during the seeds germination. It is found that the germs height after the pre-treatment with powder tannin / AM1 composite for the 10-day germination is by a factor of 1.5 higher than the height of the control sample.
