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…

Sap Flow Meter

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.…

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.…

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…

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…

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…

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…

Researchers are turning to the novel method of acoustic emissions to quantify drought stress and xylem cavitation in plants. Acoustic emissions (AE) sensors are extremely easy to install, highly robust and the results are statistically simple to analyse and interpret.   but what, exactly, are AE sensors? Acoustic emissions sensors and systems AE sensors have…

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…

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…

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 CO2meter.com Wall Mounted CO2 Detector with Alarm was installed for such reasons in…

Edaphic Scientific attended the joint conference between the New Zealand Marine Sciences Society and Australian Marine Science Association in Wellington, New Zealand. The conference was attended by over 500 marine science researchers from Australia and New Zealand. Talks and posters covered a wide range of topics from ocean acidification to coral bleaching to marine parks…

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…

CO2 Flow Meter and Detector

Author: Michael Forster, PhD.   Growers can artificially increase the amount of atmospheric carbon dioxide (CO2) available to plants to improve growth and yield. Scientists call it “atmospheric fertilization” and growers have known for a long time that increasing CO2 can improve plant productivity. Adding additional CO2 around plants is similar to adding additional nitrogen…

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…

Dr Fernanda Helfer, Griffith University, was the recipient of the 2016 Edaphic Scientific Research Equipment Grant. In this blog post, Dr Helfer explains her research on renewable energy and wastewater.   From 2013 to 2016, the global amount of fresh drinking water produced through seawater reverse osmosis desalination (RO) increased from 25 million m3day-1 to…

Soil Water Content Turf

Soil moisture, or soil volumetric water content, is easily measured with probes, sensors or handheld meters. These meters are as simple as pushing the probe or sensor into the soil, pressing read on the handheld meter, and you’re done. As easy as this appears, there are surprisingly many pitfalls and traps that can lead to wrong…

Many tropical marine species are starting to appear in temperate waters. Around Sydney, several tropical fishes, such as surgeonfish, have been observed. Corals have also been found to be overtaking algal forests off the coast of New South Wales. In New Zealand, tropical fishes have been observed in marine waters where they have never been seen…

Ever wondered what that slime is in your bathroom, or that plaque on your teeth? Most likely it is a biofilm – a community of bacteria growing within a slime on a surface that is constantly moist. Biofilms are everywhere – from that plaque on your teeth, to sewage pipes, to the guts of cows.…
