Growers workshop 2017

Posted · Add Comment

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

Posted · Add Comment

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

Posted · Add Comment

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

Posted · Add Comment

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

Posted · Add Comment

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 […]

Acoustic emissions & xylem cavitation

Posted · Add Comment

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 […]

Flowers and transpiration

Posted · Add Comment

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

Posted · Add Comment

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

Posted · Add Comment

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 […]

Marine Science Conference 2016

Posted · Add Comment

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 […]

Why your soil moisture measurements are not accurate

Posted · Add Comment

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 […]

5 reasons why CO2 levels are controlled at night

Posted · Add Comment

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 […]

Scientists adrift in the Pacific on a Kon-Tiki tour

Posted · Add Comment

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 […]

Renewable energy from the mixing of wastewater streams

Posted · Add Comment

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 […]

5 common mistakes when measuring soil moisture

Posted · Add Comment

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 […]

Is the Great Barrier Reef moving to Tasmania?

Posted · Add Comment

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 […]

what is biofilm?

Posted · Add Comment

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. […]

how plants communicate

Posted · Add Comment

can plants communicate with one another? This question is not as outrageous as it might at first seem. Certainly, plants are not like The Ents in the Lord of the Rings, coming to life and talking with one another. But scientists have amassed a large amount of evidence to suggest that plants do communicate with […]
