Innovative, inexpensive soil sensors can lead to valuable information and big results. These sensors can collect information about soil conditions and, when paired with a photograph taken from above on a smartphone, can create maps. Maps created with this technology can tell farmers where soil is acidic, where it needs more water, or other valuable metrics. With this information, farmers can improve soil quality or know where to plant which crops for the best results. The world needs more efficient farmers to feed its growing population, and big data could play a big role in increasing that efficiency.
WASHINGTON — Researchers are aiming to bring artificial intelligence and big-data technology to small-scale, developing world farms. The goal is to take on one of the 21st century's biggest challenges: feeding the world without wrecking the planet. Read More
