Special Issue Information

Dear Colleagues,

Biostimulants have emerged as potent tools in both preventing and restoring soil pollution, presenting multifaceted benefits for sustainable soil management. These substances promote plant growth and enhance the resilience of soil ecosystems, and they contribute to the long-term health of soil ecosystems, supporting agriculture and environmental conservation efforts.

The aim and the scope of this Special Issue on biostimulants include consolidating cutting-edge research that explores novel applications, mechanisms, and the ecological impact of these compounds. Researchers aim to present a comprehensive overview of the current state of knowledge on biostimulants, emphasizing their role in preventing soil pollution and facilitating the restoration of contaminated environments. The scope encompasses interdisciplinary perspectives, including agronomy, microbiology, and environmental science, to understand the integration of biostimulants in soil with advanced technologies.

This Special Issue seeks to encompass a wide array of topics, including but not limited to the following: the interactions between biostimulants and plants/soil microorganisms, field trials demonstrating the practical applications of biostimulants in preventing soil pollution, and the assessments of the long-term ecological impacts of biostimulant use. The goal is to assemble a collection of diverse and impactful research that advances our understanding of biostimulants and their role in sustainable soil management.

The use of reclaimed wastewater to irrigate crops is a valuable option due to water scarcity. However, the presence of antibiotics residues that are not removed in the tertiary treatments reaches crop soils when irrigated and it poses a serious concern for human health. Crops rhizosphere is considered a hotspot of antibiotic resistant genes (ARG) being in addition a link to plant phyllosphere and human microbiome. Understanding the structure of the soil microbiota is crucial before applying any bioremediation or biostimulation strategy. The aim of this work was firstly to confirm the presence of antibiotics residues in soil and fruits in two greenhouses at the south of Spain irrigated with reclaimed water. Secondly, to characterize the rhizosphere microbiome of three crops (Capsicum annuum, Cucumis melo and Solanum melongena) cultured in those greenhouses. Finally, a predictive functional analysis was done using PICRUSt2 to figure out the rhizosphere resistome. The presence of residues of antibiotics was confirmed both soil and fruits. Antibiotics absorbed by plants correlated with those on soil. The most abundant resistance gene was the multidrug in all the three crops tested. Compatibility of basidiomycete fungi (i.e., Pleurotus) with soil bacteria could be indicative of their possible use for restoration of agricultural soils polluted with antibiotics. Full article
