Farming on Mars: Treatment of basaltic regolith soil and briny water simulants sustains plant growth
Fig 6
(A) Growth of turnip plants (after 3 weeks) in alfalfa treated basaltic regolith simulant soil watered with unfiltered biodesalinated water or fresh water (control). (B) Flasks containing biodesalinated water before or after filtration. (C) Salinity and (D) EC of unfiltered and filtered biodesalinated water, and starting briny water simulant material. (E) Salinity and (F) EC of deionized water and fresh water (controls). At least three replicates per water type were used for salinity and EC measurements. Data represent average ± SE. (C and D) Average salinity or EC of samples that do not share a letter above the bar are significantly different (P<0.0001) as determined by one-way ANOVA.
