What to know about Evapotranspiration and how to use it to schedule irrigations

Evapotranspiration provides a relatively objective and reliable estimate of the water requirements of actively growing plants in a farm situation. Evapotranspiration information can be used by irrigators to more accurately schedule irrigations to help achieve top yields and improve water productivity.
What is Evapotranspiration?
Evapotranspiration is an estimate of the loss of […]

Renewables and Irrigation Webinar – What works and when? On and off grid systems

Agricultural research economists, Janine Powell and Jon Welsh (both AgEcon) share their findings about how and when incorporating renewable energy technologies and irrigation storage stack up.
Janine and Jon first began investigating the feasibility of renewable energy and irrigation in 2014 during the Department of Agricultures’ Carbon Farming Futures program and […]

Calculating Readily Available Water at the Macalister Irrigation Farm

A soil pit was recently dug at the Macalister Demonstration Farm (MDF) to better understand the Readily Available Water (RAW) content of the farm. RAW is the approximate amount of water measured in millimetres, held in the soil that is easily available to plants.
This water can be used by plants […]
