From the stars to the soil... agtech taking inspiration from Nasa

With global fertiliser use costing farmers up to €200bn a year, excess fertiliser is an expensive mistake

Soil testing may be revolutionised with the help of technology used on the six Rover robots, which have been landed on Mars.

There are at least two places where soil sampling is very important. On farms, and on planets where exploratory spacecraft from Earth touch down.

So it's no surprise that space technology is now being adapted for farming purposes.
