First people to colonize other planets will have to somehow grow food in place. However, extremely dry, rocky soil Mars is bad for agriculture, it lacks useful organic substances in it, so the harvest there will be meager. Scientists from the United States found a way to improve the quality of alien soil by adding a symbiotic bacterium into it.

Nitrogen is one of the most important nutrients for plants, so the lack of nitrogen molecules in Martian regolute will seriously make it difficult for local farmers. Scientists from the University of Colorado decided to enrich nitrogen regite with the help of soil bacteria, which receives nitrogen from the air,

In the pots with the simulation of the Martian soil, they planted clover, and some of them were added to the Sinorhizobium Meliloti nodule bacterium. As expected, at the company of symbiotic microbes of the plant developed better: the root system and shoots increased by 75% compared with the samples that grew in the regulate without bacteria.

«The study showed that the Bacteria sinorhizobium Meliloti forms the Nuberki in Martian regulate, significantly increasing the rise of the clover Melilotus officinalis in a greenhouse,» the authors said. — This work gives us it is better to understand how the interaction of plants and microorganisms helps in the soil terraforming of Mars. «
