Applications of Microorganisms Supported on Biochar for Soil Water Quality

Dear Colleagues,

The application of microorganisms supported on biochar represents an emerging and sustainable strategy for improving soil and water quality. Biochar provides a porous, stable, and carbon-rich matrix that enhances microbial colonization, protects cells from environmental stress, and prolongs microbial activity in soil systems.

When beneficial microorganisms such as nitrogen-fixing bacteria, phosphate-solubilizing microbes, or pollutant-degrading species are immobilized on biochar, their survival and functional efficiency increase significantly. This biochar microbe composite improves soil structure, enhances nutrient retention, and facilitates the biodegradation of organic pollutants and agrochemicals

Additionally, biochar’s high adsorption capacity reduces the mobility of heavy metals and protects microorganisms from toxicity, further supporting bioremediation. As a result, these composites help maintain cleaner soil water, reduce nutrient leaching, and promote healthier plant growth. Overall, microorganism-supported biochar offers a promising, eco-friendly approach to restoring degraded soils, protecting groundwater quality, and increasing agricultural sustainability.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
