New tensiometer-style sensor for avocado growers

Posted · Add Comment

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

Posted · Add Comment

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. […]

How accurate is the ATMOS-41 weather station?

Posted · Add Comment

The ATMOS-41 All-In-One Weather Station is a new, revolutionary design by METER Group for a weather station. The ATMOS-41 includes all common weather parameters in a compact, easy to install unit. This is the biggest difference between traditional weather stations that have large wind vanes, tipping buckets, Stevenson screen, and other bulky items. In this […]

Why this sensor has made the tensiometer and gypsum block obsolete

Posted · Add Comment

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 MPS-6 Soil Water Potential Sensor and […]

PRI Sensor

new NDVI & PRI sensors

Posted · Add Comment

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 […]

Starting in 2019, Edaphic Scientific will be the exclusive distributor for the EnviroLogix range of diagnostic testing kits for genetically modified organisms (GMO) and mycotoxins. Founded in 1996, EnviroLogix is now the world leading technology company in the detection of GMO and mycotoxins in plant materials and even for water quality. EnviroLogix is located in […]

Microsensors find refuges from ocean acidification for marine organisms

Posted · Add Comment

A recent study with Unisense microsensors has highlighted the importance of micro-refuges for enhancing the resilience of organisms and ecosystems to ocean acidification. Increasing atmospheric carbon dioxide (CO2) will lead to more CO2 being absorbed by oceans. This, in turn, will make the oceans more acidic. This process, known as ocean acidification, will have widespread […]

microsensor workshop 2018

Posted · Add Comment

Edaphic Scientific and Unisense recently hosted Prof. Michael Kühl, University of Copenhagen, for a microsensor workshop held at the University of Melbourne, Australia. The workshop covered topics such as microsensor theory and analysis, as well as case studies including microsensors in biogeochemistry, coral physiology, marine science, biofilms, climate change and wetlands, and use in biomedical […]

Controlling biofilm effects on wetland ecosystems

Posted · Add Comment

New research has found a simple method that can improve wetland stability, biodiversity and ecosystem functioning. By simply increasing the flow rate of water around wetlands, the growth and impact of biofilms on underwater vegetation decreases. This approach can have significant benefits for constructed wetlands or the rejuvenation of degraded wetland ecosystems. Biofilms are integrated […]

Grapevines, sap flow and heatwaves

Posted · Add Comment

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

Detection of tree disease with sap flow sensors

Posted · Add Comment

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. […]

Micro pH Electrode

Measure in micro volumes

Posted · Add Comment

The range of microsensors supplied by Edaphic Scientific can be extremely small – down to only 3 µm in diameter! The microsensors are highly suitable to measure small and micro volumes, droplets, or thin surface layers such as biofilms or biological tissues. The microsensors are also suitable for measuring inside standard lab equipment such as Eppendorfs. Systems […]

Biomedical biofilm research

Posted · Add Comment

Rapid advances in biomedical research on biofilms have recently been made thanks to the Unisense range of microsensors. Biofilms are colonies of micro-organisms, including bacteria and fungi, that are found just about everywhere including on your teeth, in the bathroom, and in sewers and drains. While many biofilms are benign, or even beneficial, there are […]

The Grape Monitor

Posted · Add Comment

Edaphic Scientific was recently commissioned by the New South Wales Department of Primary Industries (NSW DPI) to install a series of plant physiology monitoring stations on grapevines. Known as The Grape Monitor, the stations were installed in the Riverina district of western New South Wales, Australia, near the town of Griffith. Four grape varieties are […]

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 […]
