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.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
