Leveraging tools from seismology — the study of earthquakes and the inside of our planet — the Earth Rover Program aims to provide critical data on the health of soil. Humans, and terrestrial life in ...

For centuries, agriculture has relied on three essential assets: land, water and seed. In the 2020s, however, a fourth asset has become equally critical: data. I have spent much of the past year ...

UjuziKilimo has today, December 20, 2025, launched SoilPal Pro, the world’s first smartphone-based soil testing solution. This device enables farmers and businesses to conduct on-site, ...

Dirt. For millennia, the dark, rich soil underlying farms and gardens worldwide has been central to human survival. It’s also a lot more complex than it looks. Within every clump of soil lies an ...

CU Boulder Today—A team of University of Colorado Boulder researchers is making reliable, inexpensive and easy-to-deploy sensors that monitor soil in real time as it, essentially, breathes in and out.

Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and weather monitoring solution built around the company’s own Novaduino Display ...

Use a capacitive soil moisture sensor (it’s corrosion-resistant). If using a resistive type, power the sensor only during readings (use a transistor or MOSFET controlled by Arduino).
