Irrigation with sap flow sensors: a video explainer
Irrigation managers face two questions: when and how much to irrigate. A new video, available on YouTube and with a weblink below, explains how sap flow sensors can be used for irrigation scheduling and dosing. Sap flow sensors measure crop water use or transpiration. With a sap flow sensor, it is possible to determine how…
Read MoreMeasuring CO2 levels in moviegoer emotions
Carbon dioxide (CO2) sensors are used for a wide range of applications from indoor air quality, to medical and environmental monitoring. But now CO2 sensors can also be used to measure human emotions!

Read MoreSap flow, evapotranspiration and irrigation management
Irrigating scheduling and amount can be accurately determined by combining sap flow (crop water use) sensors and evapotranspiration (ETo) data. This article outlines how growers, researchers or physiologists can use the Implexx Sap Flow Sensor, alongside the ATMOS 41 weather station, or the Implexx Evapotranspiration (ETo) station. Although this article has a focus on grapevines,…

Read MoreReducing urban water pollution with water level sensors
Urban storm water drain pollution can increase during dry weather and become an environmental problem. Water level in drains increases because of transient sources such as over-irrigation of gardens, car washing, cleaning of footpaths, as well as constantly-flowing sources such as groundwater infiltration and broken underground pipes. This is known as dry-weather flow, or non-stormwater…

monitoring water uptake and transport of a model rainforest ecosystem Author: Kathrin Kühnhammer PhD Student at TU Braunschweig, Environmental Geochemistry, Germany Together with a large group of scientists from all over the world, the junior research group “Isodrones” (www.isodrones.de) took part in the highly interdisciplinary research project B2 WALD (Water, Atmosphere and Life…
Read MoreThe Amerigo Lander: a novel underwater device to measure human oceanic impacts
It is no secret that humans are heavily impacting oceans. Measuring these impacts, however, is extremely difficult. Not only are the oceans vast but incredibly deep with the ocean floor at least 6000m down in many locations. Precise measurements of biogeochemical and ecological processes at these depths is technologically hard. An Italian research group from…

Edaphic Scientific supplies a large range of carbon dioxide (CO2) detectors that are suitable for greenhouses and glasshouses. In this article, our supplier of CO2 detectors, CO2Meter, interviewed researchers from NC State University on how they deploy CO2 sensors in their greenhouses. This article originally appeared on the CO2Meter.com website. One intriguing CO2Meter collaboration…
Read MoreBushfires and assessing the risk of erosion
After a long season of bushfires in Australia, many of which are still burning, it is important to look forward to recovery and regeneration. There is much to do, measure and assess. Among these is the risk of soil erosion particularly where heavy rainfall, or high winds, impact bare ground. This article was first published…
Read MoreImplexx Sap Flow Sensor: a new sap flow sensor for the digital age
A new sap flow sensor has been released by Implexx Sense! The Implexx Sap Flow Sensor is a low cost, easy to use and maintain sap flow sensor designed by scientists and engineers from the Australian company, Implexx. Implexx Sap Flow Sensor was designed with the scientists and grower in mind – it has all…
Read MoreSap flow data show grapevines can tolerate extreme heatwave events
Monitoring sap flow on grapevines during extreme heatwave events has demonstrated that vines can tolerate extreme conditions when soil moisture levels were high. These results were found via the grapevine and heatwave monitoring project in the Riverina region of New South Wales (NSW), Australia. Heatwaves are “three or more days of high maximum and minimum…
Read MoreA new introductory video on sap flow
What is sap flow? Is it water or sugars in the plant? What is the difference between sap flow and transpiration? Why measure sap flow? If you are new to the world of sap flow science, then the team at Implexx and Edaphic Scientific have released a new video for you. Sap Flow: An Introduction…
Read MoreSouth Australia to introduce GMO crops
The South Australian government is planning on ending the ban on genetically modified (GMO) crops. South Australia is one of the last jurisdictions in Australia to have a ban on GMO crops such as canola. But, legislation to be introduced in December 2019 by Minister for Primary Industries and Regional Development Tim Whetstone will lift…
Read MoreNew tensiometer-style sensor for avocado growers
A new, tensiometer-style sensor is improving irrigation management and saving time and costs for avocado growers. Irrigation monitoring and scheduling often relies on tensiometers – sensors that can measure soil water potential. Tensiometers are a favourite among avocado growers but they come with a huge problem: they are extremely tedious and odious to maintain. A…
