The AP4 Porometer measures stomatal aperture in terms of leaf conductance to water vapour.

This is a major determinant of water loss from plant leaves and of CO2 uptake in photosynthesis.

The innovative design of the AP4 provides users with logical, convenient operation and a comprehensive range of features and functions. Key benefits include an automated, rapid cycle that gives accurate temperature compensated readings, and a straightforward highly effective field calibration

Rothamsted Research is the longest-running agricultural research institute in the world, with a history dating back to the middle of the 19th century.

Sir John Bennet Lawes, an archetypal Victorian scientist, entrepreneur and benefactor, became interested in agricultural science after leaving Oxford University. On assuming responsibility for the family estate at Rothamsted (Harpenden, Hertfordshire, UK), Lawes started several small-scale experiments involving inorga

The Experiment

The Jena Experiment is a long-term biodiversity focused research project funded by the German Research Foundation (DFG).

The large scale project has been running since 2002 and involves over 100 scientists. The research is centred around discovering which mechanisms influence ecosystem functions and make them stable.

The project takes place on a 10 hectare site in Jena, Germany – which consists of approximately 600 plots of a

SBR Agricultural Products (SBR) was founded in 1990 and operates in the Mersin Silifke region of Turkey. It specialises in the cultivation of fruit, especially berries – using cutting edge techniques.

Its growing facilities are substantial – with 400,000 square metres of hydroponic strawberry greenhouses, and separate 50,000 square meter production areas for raspberry, blackberry and blueberry.

DeltaLINK-Cloud is an online service for viewing, sharing, storing and managing data uploaded from Delta-T data loggers. DeltaLINK-Cloud has always featured graphing, but now also supports animated live data dashboards.

DeltaLINK-Cloud dashboards enable you to display selected data using widgets (simple graphical devices such as dials and trend lines). You can control the type, colour and position of widgets to create an attractive information panel –  ensuring that critica

Delta-T Devices has created a new 3 minute animated video, providing a comprehensive and visually engaging overview of the PR2 Profile Probe.

It explains how the PR2 works, how it is installed – and how it can be used to obtain accurate measurement of soil water content at defined depths down to one metre.
 

The video also shows how a PR2 Profile Probe can be used for both instant portable readings (at multiple locations) and long term monitoring at a

Poinsettias, the classic Christmas pot plant, are grown in their thousands in UK nurseries from late July onwards, but growers have to rely on the use of plant growth regulators (PRGs) to ensure that the optimum height and number of bracts is achieved by early December.

With protective environmental legislation threatening to reduce the availability and use of such PGR treatments, a project led by the University of Lincoln and funded by the AHDB for the BPOA Poinsettia Group

Marine AOD measurements matter because aerosols can affect respiratory health, climate change, and the safety of aircraft during volcanic events. However, routine marine Aerosol Optical Depth (AOD) surface-based observations are in short supply because it is both difficult and expensive to operate conventional automatic sun photometers at sea.

Two prototype hyperspectral radiometers have shown that Global and Diffuse irradiance and AOD can successfully be measured autonomousl

Delta-T Devices has launched a new digital version of their well-established analogue PR2 Profile Probe.

Named the PR2 SDI-12, it shares the many strengths of the analogue version (which remains in production), but with the addition of SDI-12 compatibility – allowing integration into new and existing SDI-12 systems. As with the analogue version, the new version comes in two lengths – to measure soil moisture profiles down to 40cms or 100cms.

The PR2 SDI-12 builds o

The Delta-T DevicesWS-GP1 Weather Station is a complete, portable, research-grade solution for recording weather data. It can be carried by one person, set up in minutes, and requires minimal maintenance. The WS-GP1’s sensors measure rainfall, solar radiation, wind speed, wind direction, relative humidity and air temperature.  The sensors are dependable, carefully matched, and suitable for use in demanding en
