abstract = {Climate change negatively affects agriculture, causing desertification, salinisation, and
drought. The biochar hydroinfiltrator (ES Patent No.: ES2793448 B2) is a device that
increases the capture of rainwater or irrigation water for crops by increasing infiltration
rates. Biochar, produced via biomass pyrolysis, has emerged as a promising agricultural
amendment, as it helps to optimise moisture retention and improve soil structure, key
aspects for boosting crop yields. There is growing interest in microorganisms’ plant-growthpromoting activity (PGP) by carrying out different activities considered growth promoters.
The aim of the present study is to evaluate the use of a biochar hydroinfiltrator as a promoter
of microbial activity when it is used in soil. Metagenomic analysis of soils with and without
the device reveals that genera Bacillus and Sphingomonas became particularly enriched in
soils with hydroinfiltrators. Also, in order to understand the interaction between the uses
of biochar together with bacteria PGP, an in vitro test was carried out. Two microorganisms,
previously selected for their characteristics as plant growth promoters, were inoculated
in soils with and without biochar and they grew better after 15 to 30 days of inoculation,
showing major CFU counts. This combined strategy—biochar hydroinfiltrator and PGP
bacteria—offers an innovative, eco-friendly approach to sustainable agriculture, particularly
under drought stress.},
