This work includes the soil and crop plants samples results from region in Slovak Republic - Bojnicky which is contaminated by acid pollutants and heavy metals. First chemical analysis on risk elements (RE) contents in these samples was realized. Tested plants were buckwheat, amaranth and millet. These non-conventional plant species samples were taken from agricultural enterprise, from producers. Buckwheat and amaranth can be used for a variety of baked products including pancakes, breads, muffins, crackers, bagels, cookies, and tortillas among others. It is thought of as a cereal, but is actually an herb of the buckwheat family, Polygonaceae. Millet is one of the smallest grains with higher protein content than corn, barley or sorghum. In 2 pot experiments millet and buckwheat were cultivated in soil from key region. Then the substances were added into the soil of 6 variants to arrange pH reaction and to lower toxic elements input into the both crop plants. Then the results from this survey and from the above mentioned one were evaluated and compared. The purpose of this study is to demonstrate the changes of heavy metals mobility in crop plants and to clarify the importance of heavy metals monitoring in Slovak types of soil. The results from our experiment show that relatively low RE soil content could not mean that the plants like amaranth, millet and buckwheat will not absorb significant concentrations of risk elements (RE) and these can cause harmful affecting on plants in final point. Our next study will concern phenol compounds content changes within the influence of RE (metallic burden from soil vs. rutin content changes, etc.).
