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.…

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…

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…
Read MoreDetection 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
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…

Measuring transpiration of small plants
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
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
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
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
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…
