South Australia to introduce GMO crops

Canola GMO Australia

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 sensors and water wise research

Leaf Temperature Sensor

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.…

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…

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…

Detection of tree disease with sap flow sensors

Sap flow sensors can be used to study the hydraulic function of healthy versus diseased trees. Sap flow sensors can detect a decrease in hydraulic function associated with disease prior to the onset of outward, physical symptoms. Sap flow sensors, therefore, provide a tool for researchers to better understand the physiology of disease in trees.…

Growers workshop 2017

Edaphic Scientific participated in a series of workshops for macadamia and grape growers in November and December, 2017. The workshops covered topics such as heatwaves, irrigation and advanced technology to measure the water potential of crops. The workshops were organised by the Department of Primary Industries (DPI) New South Wales, and the Australian Macadamia Society.…

Dendrometers: multi-purpose sensors

Fruit Physiology

Dendrometers are a multi-purpose sensor for measuring plant growth and water use. They are a precision sensor to measure small expansion and contractions in plant tissues over a daily cycle. They can also measure growth over several days, weeks and months. Therefore, dendrometers can be used for irrigation and fertigation management, as well as providing…

A novel method to measure algal blooms

Algal blooms can cause significant environmental damage producing toxic effects on people, freshwater and marine organisms. Understanding and quantifying algal blooms often involves expensive or laborious scientific equipment. However, researchers at the USA Environmental Protection Agency recently adopted a novel method to study algae in a river system in the United States. The methods involves…

How the landscape influences GHGs in tropical forests

Soil GHG Sensor

A case study from Eosense: Tropical rainforests are large sources of carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4), which are known to be potent greenhouse gases (GHGs). Despite this, greenhouse gas flux in tropical rainforests is not well studied due to the difficulties of deploying and maintaining equipment. This gap in knowledge is…

Measuring transpiration of small plants

Sap Flow Meter

Continuous measurements of the water use, or transpiration, of small or herbaceous plants can be difficult. A small weighing lysimeter, also known as a balance or scale, can be used however these often require a researcher to manually read the LCD screen or to have the instrument connected to a PC or laptop. Data collection…

Flowers and transpiration

flower transpiration

Surprisingly little research has been dedicated to flower water relations. This is despite the vast amount of research on water relations at the whole-plant level, stomatal conductance at the leaf level, and even the water relations of fruits. Flowers have been largely neglected probably due to the difficulty of accurately measuring transpiration rates with a…

Plant and Soil Workshops 2016

Edaphic Scientific has just held a series of one day workshops on water and nutrients in plants and soils. The workshops were held across Australia at the CSIRO, Macquarie University and The University of Queensland and were well attended by students, researchers and growers. The workshop consisted of a series of presentations followed by practical…

Monitoring CO2 in Shopping Centres

CO2 Detector Green Building Council of Australia

You have probably never noticed a CO2 (carbon dioxide) detector when you’re at the shopping centre buying new clothes or shoes. More and more CO2 detectors are being installed in shopping centres to monitor CO2 for comfort and energy savings. Recently, the Wall Mounted CO2 Detector with Alarm was installed for such reasons in…

Why your soil moisture measurements are not accurate

Manufacturers of soil water content sensors supply their product with an output registering volumetric water content (VWC), typically expressed as a percentage. But where does this number come from and what does it actually mean? In all likelihood, the output value from the sensor will not be equal to the actual VWC of your particular…

Scientists adrift in the Pacific on a Kon-Tiki tour

What would possess a team of scientists to drift on a primitive raft in the Pacific Ocean for over 60 days? As always, it is in the name of science – specifically anthropology and environmental science research. Known as the Kon-Tiki2 Expedition, the scientists are examining if it was possible for Polynesian and South American…
