CO2 sensors in a greenhouse laboratory

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…

Bushfires 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…

sap flow and heatwaves

Sap 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…

Canola GMO Australia

South 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…

New 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…

Leaf Temperature Sensor

Leaf temperature sensors and water wise research

Plant physiologists and irrigation scientists need accurate and reliable leaf and canopy temperature sensors for scientific research. Recently, the LT-1T Leaf Temperature Sensor from Edaphic Scientific was deployed by researchers at the CSIRO for a project on irrigation management of tomato crops. The LT-1T is a small, temperature sensor that firmly clips onto a leaf.…

METER Group TEROS-21

Why this sensor has made the tensiometer and gypsum block obsolete

New and improved technology is now available for growers that is enabling more efficient and lower cost irrigation. The technology is a significant improvement on older, tensiometer and gypsum block style sensors by requiring zero maintenance, having a higher accuracy and being more robust. The technology is called the TEROS 21 Soil Water Potential Sensor…

PRI Sensor

new NDVI & PRI sensors

Edaphic Scientific is now supporting the new range of Spectral Reflectance Sensors to measure NDVI and PRI. NDVI (Normalised Difference Vegetation Index) and PRI (Photochemical Reflectance Index) are important plant canopy parameters that provide information on canopy water, nutrient and light stress. The new SRS sensors are a significant improvement on old technology as they…

Grapevines, sap flow and heatwaves

Heatwaves can have a significant impact on grapevines, scorching leaves and decreasing growth and yield. Grape growers deploy various strategies to protect their vines during extreme heat events which can include spraying canopies with “sunscreen”. Although these strategies have merit, they often involve investment in additional infrastructure or are laborious to employ. Another strategy involves…
