A just released study published in the journal Plants documented the results of experiments to find the best ratio of compost to Martial soil simulant to effectively grow nutritious butter lettuce with the least amount of water while optimizing crop performance. Such findings will enable in situ resource utilization and reduce the mass of supplies needed to be transported to Mars to support farming in human settlements.
