Rosy future for Leeds-developed mulch


Gardeners will soon have access to an environmentally-friendly garden mulch product developed at the University of Leeds, thanks to a £30,000 award won by its inventor.

The straw-based mulch – called Strulch – was developed by Dr Geoff Whiteley in the School of Biology. It will be marketed by Ingwermat, a company formed to use patents developed at Leeds, with the help of the Home Grown Cereals Authority Enterprise award.

The mulch is made from shredded straw treated with iron minerals which turn it brown and slow the rate of decomposition. It lasts for up to two years, is effective in weed control, reduces the need for watering in the garden and is a deterrent against slugs and snails.

All mulches reduce evaporation and hinder weed growth. Straw mulches are commonly used in arid countries but not extensively in the UK because they rot quickly or look unsightly. Strulch is stable against decomposition and visually acceptable.

Dr Whiteley said: “We are targeting gardeners to encourage them to use Strulch on more areas in the garden such as perennial beds and vegetable plots because it works well and is very competitively priced.”

Strulch is environmentally-friendly because it is made from locally produced wheat straw rather than chip bark and other imported mulch products.

It is already being used by the Eden Project, the Royal Horticultural Society Harlow Carr Gardens, the Earth Centre at Doncaster and Helmsley walled gardens.

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
