Catalogue: Ground Cover
The field-based trials will create a micro-atmosphere around plots of crops by raising the level of carbon dioxide (CO 2 ) in the air around the plants to 550 parts per million (ppm) - a level the Intergovernmental Panel on Climate Change expects the atmosphere will exceed this century... The level of CO 2 in the atmosphere is about 380ppm... Professor David McNeil, chair of agricultural science at the University of Tasmania, who established the project with the University of Melbourne's Professor Rob Norton, says it is vital for Australian farmers reliant on producing a premium product to know what to expect from their crops as CO 2 levels rise...

Rising levels of carbon dioxide (CO 2 ) in our atmosphere will affect almost every aspect of crop production, from nutrition to plant breeding, grain quality and pest and disease threats... The concentration of CO 2 in the atmosphere is just greater than 400 parts per million, and the experiments run by the AGFACE team are exposing crops to concentrations of 550ppm, which is the predicted measure of atmospheric CO 2 by 2050... "We have also found that important micronutrient levels decrease under CO 2 , such as zinc and iron, which could contribute to human malnutrition in areas of the world where access to food is an issue."..
