Z<strong>in</strong>c, copper and manganese are obta<strong>in</strong>ed by plants <strong>in</strong> ion form. Use of metal salts<br />
as components of solvable microfertilizers is <strong>in</strong>efficient because salts, as well as complex<br />
metal compounds, are easily washed out. We studied <strong>the</strong> possibility of prolonged support<br />
of plants <strong>with</strong> microelements by <strong>in</strong>troduc<strong>in</strong>g ions and complex microelement compounds<br />
<strong>in</strong> soil <strong>in</strong> form of nanocomposite materials of <strong>the</strong> "host-guest" type.<br />
Objectives. Our ma<strong>in</strong> objective was to obta<strong>in</strong> nanocomposite materials of "host-guest"<br />
type based on <strong>the</strong> research of natural zeolites and complex ions of z<strong>in</strong>c, copper and<br />
manganese, and to study <strong>the</strong>ir effect <strong>in</strong> real-world conditions <strong>in</strong> gra<strong>in</strong> and vegetable crop<br />
rotation rotation (results of <strong>the</strong> first stage (1 year) of <strong>the</strong> 3-year study are prsented.).<br />
Methods. Natural zeolites were impregnated by complex ions of z<strong>in</strong>k and copper<br />
[Cu(NH 3 ) 4 ] 2 + and [Zn(NH 3 ) 4 ] 2 + <strong>in</strong> aqueous solution. Zeolite-manganese nanocomposite<br />
was obta<strong>in</strong>ed us<strong>in</strong>g <strong>the</strong> aqueous solution of MnCl 2. Both zeolite portions were mixed and<br />
<strong>in</strong>troduced <strong>in</strong>to soil. Field experiments were conducted on carrot and beetroot. We<br />
compared our results <strong>with</strong> seeds treated <strong>with</strong> microfertilizers.<br />
Results. Use of nanocomposite materials <strong>in</strong>creases concentration of z<strong>in</strong>k by 50% <strong>in</strong> carrot<br />
(up to 3 mg/kg) and by 100% <strong>in</strong> beetroot (up to 4 mg/kg). Copper concentration <strong>in</strong> both of<br />
<strong>the</strong>se plants <strong>in</strong>creases by 30% compared to control samples. Manganese concentration <strong>in</strong><br />
vegetables is not affected by change of technology. Process<strong>in</strong>g of seeds <strong>with</strong><br />
microfertilizers has no <strong>in</strong>fluence on concentration of microelements <strong>in</strong> vegetables.<br />
Conclusions. Use of nanocomposite materials allowed decreas<strong>in</strong>g mobility of<br />
microelements <strong>in</strong> soil which led to <strong>the</strong> <strong>in</strong>crease of z<strong>in</strong>c and copper concentration <strong>in</strong> carrot<br />
and beetroot.
