Scientists identify ideal Mars farming sites
A team from the University of Sydney developed a comprehensive classification of Martian soil and successfully created a map covering 92% of the planet's surface aimed at identifying the best locations for planting crops. Relying on the integration of orbital data and models helped classify around two thousand soil types based on multiple properties such as texture, mineral content, acidity, and layer thickness. Tests revealed that the soil type known as "Noehipareth" is the most promising, with a high productivity score of 0.93. This soil is primarily concentrated in limited areas. However, challenges such as water retention, the absence of organic materials, and the toxicity of perchlorates may hinder farming efforts on Mars. Currently, scientists are experimenting with soil blends that mimic Martian soil on Earth to address these issues, with potential benefits from these studies in understanding the performance of arid soils on Earth as well.
