CONTEXT
Research interest in the development of microbial biostimulants has grown strongly in recent years. Indeed, these solutions increase the bioavailability of nutrients (N, P, S, K, Ca, Mg...) and/or improve plant growth by limiting the use of mineral fertilizers.
DESCRIPTION
Recently, researchers of the Agronomy & Environment laboratory at Nancy (France) have identified two bacterial strains of the rhizosphere capable of efficiently mineralizing organic nitrogen (N) and sulphur (S) in the soil and stimulating the plant's root growth. The strains were selected for their ability to increase enzymatic activities involved in the mineralization of organic forms of N and S in soil. These are protease/aminopeptidase activities for N and arylsulfatases for S. The inoculation of an agricultural soil shows a significant stimulation of these enzymatic activities allowing the increase of mineral nitrogen availability (in nitrate forms). On corn, the strains showed a stimulating effect on the root growth of plants at the 1-2 leaf stage.
