New data were obtained regarding the specific amino acid diversity in the soils of Moldova. This index proved to be maximal in the control soil, with values lower by 52% in the mineral soil, and by 50% lower in the organic and natural one. The Mergalef and Menhinik diversity indices proved to be higher in the control soil by 2%, 8% and 15% and by 7%, 29% and 48%, respectively. The highest concentration of amino acid dominance was recorded in unfertilized soil (c = 2.1025). In other variants, Simpson index had similar values and accounted for 48% in mineral and natural funds and for 50% - in the organic ones. The structure of AA communities was characterized by a varied relative participation of biomolecules range and uneven redistribution. In ploughed soils the Shannon index was lower on average by 33%, which is an additional evidence of the impoverishment of the specific diversity spectrum of amino acids and of their variety, due to human impact.
