Bio-products are increasingly used in agricultural production owing to their multiple advantages: they decompose organic matter, enter in dynamics with the humus from soil, fix nitrogen (N) from the atmosphere, solubilize fixed nutrients by clay-humic complex, block Fe3+ i.e. This paper presents the results obtained from using a complex of bioproducts: GeoCell-1, GeoAgit CNPK-1 and AlgaSanBa. They were applied either alone or in a complex mixture. The subsequent increase in the grain yields was important. Thus, winter wheat varied between 210 and 1010 kg.ha-1 on chernozem, and between 490 and 1430 kg.ha-1 on luvisol. Under the same conditions, sunflower increases varied between 290-730 kg.ha-1 on the first soil and 110-1190 kg.ha-1 on the second soil. Maize produced an addition of 70- 1030 kg.ha-1 in the first case and 110-1190 kg.ha-1 in the second case. The data demonstrate that the new bio-products are recommended for use in farm fields.
