Reducing water inputs with on demand irrigation scheduling

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…

Irrigation with sap flow sensors: a video explainer

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…

Measuring CO2 levels in moviegoer emotions

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…

Sap flow, evapotranspiration and irrigation management

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,…

Reducing urban water pollution with water level sensors

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…

The Amerigo Lander: a novel underwater device to measure human oceanic impacts

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…

Bushfires and assessing the risk of erosion

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…
