Taxonomic response of bacterial and fungal populations to biofertilizers in greenhouse cucumber soil

Reductions in the quality and yield of crops continuously produced in the same location for many years due to annual increases in soil-borne pathogens. Environmentally-friendly methods are needed to produce vegetables sustainably and cost-effectively under protective cover.

The researchers investigated the impact of biofertilizers on cucumber growth and yield and changes to populations of soil microorganisms in response to biofertilizer treatments applied to substrate or soil. The researchers observed that some biofertilizers significantly increased cucumber growth and decreased soil-borne pathogens in soil and substrate.

Rhizosphere microbial communities in soil and substrate responded differently to different biofertilizers, which also led to significant differences in microbial diversity and taxonomic structure at different times in the growing season. Biofertilizers increase the prospects of re-using substrate for continuously producing high-quality crops cost-effectively from the same soil each year while at the same time controlling the soil-borne disease.
