Farmer tests soil using robots.

A farmer in Cornwall is collaborating with scientists from the University of Plymouth to test robots, including robotic dogs, to measure soil health on his farm. Soil, composed of rock particles, organic matter, water, and air, is crucial for providing plants with essential nutrients for growth. The robots, equipped with gamma ray detectors, can quickly assess soil moisture and organic matter levels, offering farmers efficient and cost-effective soil testing solutions. These robotic dogs are designed to navigate various terrains, providing farmers with rapid results to enhance soil health and optimize crop planting decisions. [Extracted from the article]
