Soil parameters and bioindicators to assess prebiotics effects on soil health and plant growth

Résumé

In the last decade, the exponential increase in the number of biostimulants released onto the market has raised the researcher’s curiosity to study and evaluate these alternative products. The variability in the efficiency of these products after application requires a better understanding of their modes of action. For this purpose, it is necessary to define and validate indicators that can provide information on these products' effects in improving nutrient availability, nutrient use efficiency, and plant/microorganisms' interactions. In our work, we present a scientific assessment process of different commercial prebiotics that have been seen to cause positive effects on soil and crops when applied in agricultural fields. Multispectral analyses were performed at two harvesting dates after the products’ application on soil mixed with organic wheat straws and cultivated with Zea mays L. in comparison to untreated soil. In this context, we monitored plant growth criteria, soil physicochemical parameters, soil organic matter (OM) evolution, and soil microbial community structure and diversity with an emphasis on indigenous microbial selection and root mycorrhization. This set of indicators presented a relevant tool to study the short- and medium-term effects of prebiotics on soil fertility and microbial community and their repercussions on plant growth and carbon storage. So, our experimental design is a good example of how to study the prebiotics’ functionality and evaluate their efficacity. At the end, our aim is to confirm the vital role that prebiotics will play as an innovative approach in the agroecological transition.
