Scientists Turn Martian Regolith Into Cropland With Fungi, Cutting Need to Ship Soil
2 articles · Updated · Futurism · May 31
A new study says fungi could transform Mars’s alkaline, toxin-laced regolith into soil capable of supporting crops and a longer-term human presence.
The researchers say species such as trichoderma can metabolize toxic aluminum and manganese while generating phosphates and other nutrients plants need to grow.
Other candidates include Cryomyces antarcticus—shown to survive space exposure—and mycorrhizal fungi that can boost iron uptake, reduce oxidative stress and improve soil structure.
Major unknowns remain, including whether food grown in treated regolith would be safe to eat, how radiation would affect crops and how the concept can be validated before settlement.
The approach could sharply lower Mars mission costs by avoiding shipped growing media, adding to early progress such as a Bremen-DLR algae fertilizer made entirely from Martian resources.

Fungi Turn Martian Regolith into Fertile Soil: The Breakthrough Paving the Way for Sustainable Mars Colonies
Overview
Growing food on Mars has been a major challenge because Martian regolith lacks organic content, is low in essential nutrients like nitrogen, phosphorus, and potassium, and contains toxic substances such as perchlorates. These harsh physicochemical constraints make traditional gardening nearly impossible. However, recent breakthroughs show that certain fungi, especially arbuscular mycorrhizal fungi (AMF), can transform this barren regolith into a more plant-friendly environment. AMF act as microscopic extensions of plant roots, helping plants absorb nutrients and overcome environmental stress. This discovery marks a promising step toward sustainable agriculture and future human settlements on Mars.
