Scientists have developed a new "intelligent" reliable soil moisture sensor that is set to ensure horticulturists accurately irrigate staple crops such as potatoes and fruit, and enhance environmentally friendly farming practices. A collaboration between the University of Warwick and Herefordshire based McBurney Scientific led to the development of the new product that harnesses enhanced sensor technology for measuring soil moisture with wireless communication and the processing power and convenience of the hand-held computer.
Soil moisture conditions play a vital role in ensuring good crop quality and quantity, and the new device is set to simplify the task of measuring and reduce the costs of irrigation scheduling by more than £10 per hectare each year, compared with current soil measurement equipment. The battery-powered probe is a significant improvement on existing devices, which use complex technology and are often too expensive for use in low-margin crops.
Heat pulse technology embedded in a porous ceramic tip on the probe measures soil moisture content. Readings are then sent via radio signals to a hand-held computer, which can interpret the results to show how much water is needed to optimise growing conditions, depending on factors such as soil type. It automatically downloads the data within a 100 metres range of the sensor.
Consumers demand high quality fruit and vegetables as well as environmentally sensitive methods of crop production, and the amount and timing of irrigation are crucial factors in ensuring a good crop.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
