New research has shown up to 40% reduction in irrigation can be achieved with soils or plant based decision making. Water resources are becoming increasingly expensive and scarce. To reduce costs and save on water, it is possible to alter irrigation scheduling (i.e. timing and dosing). Yet, when altering or decreasing irrigation it is critical…

SFM1 Sap Flow Meter

Irrigation managers face two questions: when and how much to irrigate. A new video, available on YouTube and with a weblink below, explains how sap flow sensors can be used for irrigation scheduling and dosing. Sap flow sensors measure crop water use or transpiration. With a sap flow sensor, it is possible to determine how…

Carbon dioxide (CO2) sensors are used for a wide range of applications from indoor air quality, to medical and environmental monitoring. But now CO2 sensors can also be used to measure human emotions! In this article, originally published on the CO2meter.com blog, researchers from Germany’s Max Planck Institute discuss how they used CO2 sensors to…

Grape Crop Water Use

Irrigating scheduling and amount can be accurately determined by combining sap flow (crop water use) sensors and evapotranspiration (ETo) data. This article outlines how growers, researchers or physiologists can use the Implexx Sap Flow Sensor, alongside the ATMOS 41 weather station, or the Implexx Evapotranspiration (ETo) station. Although this article has a focus on grapevines,…

Edaphic Scientific is now the exclusive distributor in Australia and New Zealand for Sea & Sun Technology. We are excited by the opportunity to support Sea & Sun Technology in our part of the world! Sea & Sun Technology is a world-leading, German manufacturer of water-based sensors for marine science, oceanography, limnology, hydrology, hydrography, groundwater,…

Urban storm water drain pollution can increase during dry weather and become an environmental problem. Water level in drains increases because of transient sources such as over-irrigation of gardens, car washing, cleaning of footpaths, as well as constantly-flowing sources such as groundwater infiltration and broken underground pipes. This is known as dry-weather flow, or non-stormwater…

EcoSystem Farms is utilising modern techniques in aquaponics to create a natural farming system that is -cide free – that is no herbicides or pesticides! Based on the Fleurieu Peninsula, South Australia, EcoSystem Farms deploys ecological principles to create a natural loop between fish and plants where the fish provide the nutrients and the plants…

Implexx Sense has released a new range of low cost, IoT-enabled, water level, depth or pressure sensors. The Implexx Water Level Sensor is ideal for hydrologists and irrigation managers. The water level sensors can be installed in tanks, boreholes, streams, lakes, rivers, estuaries and marine environments, to a depth of 200 metres. The Implexx Water…

monitoring water uptake and transport of a model rainforest ecosystem Author: Kathrin Kühnhammer PhD Student at TU Braunschweig, Environmental Geochemistry, Germany Together with a large group of scientists from all over the world, the junior research group “Isodrones” (www.isodrones.de) took part in the highly interdisciplinary research project B2 WALD (Water, Atmosphere and Life…

It is no secret that humans are heavily impacting oceans. Measuring these impacts, however, is extremely difficult. Not only are the oceans vast but incredibly deep with the ocean floor at least 6000m down in many locations. Precise measurements of biogeochemical and ecological processes at these depths is technologically hard. An Italian research group from…

Edaphic Scientific supplies a large range of carbon dioxide (CO2) detectors that are suitable for greenhouses and glasshouses. In this article, our supplier of CO2 detectors, CO2Meter, interviewed researchers from NC State University on how they deploy CO2 sensors in their greenhouses. This article originally appeared on the CO2Meter.com website. One intriguing CO2Meter collaboration…

After a long season of bushfires in Australia, many of which are still burning, it is important to look forward to recovery and regeneration. There is much to do, measure and assess. Among these is the risk of soil erosion particularly where heavy rainfall, or high winds, impact bare ground. This article was first published…

A new sap flow sensor has been released by Implexx Sense! The Implexx Sap Flow Sensor is a low cost, easy to use and maintain sap flow sensor designed by scientists and engineers from the Australian company, Implexx. Implexx Sap Flow Sensor was designed with the scientists and grower in mind – it has all…

Monitoring sap flow on grapevines during extreme heatwave events has demonstrated that vines can tolerate extreme conditions when soil moisture levels were high. These results were found via the grapevine and heatwave monitoring project in the Riverina region of New South Wales (NSW), Australia. Heatwaves are “three or more days of high maximum and minimum…

What is sap flow? Is it water or sugars in the plant? What is the difference between sap flow and transpiration? Why measure sap flow? If you are new to the world of sap flow science, then the team at Implexx and Edaphic Scientific have released a new video for you. Sap Flow: An Introduction…

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…

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 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.…

METER Group TEROS-21

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

Edaphic Scientific is now supporting the new range of Spectral Reflectance Sensors to measure NDVI and PRI.
