More Profit from Crop Nutrition: Micronutrient Survey

A scoping study to develop a risk assessment for micronutrient deficiency in the grains industry.


A national survey of the extent of micronutrient (zinc, copper, managanese, boron, molybdenum) deficiencies across all regions and agroecological zones with analysis against environmental and management metadata by 2013. Micronutrients or trace elements have been proposed as the next major nutrient limitation to improved grain production. Copper, zinc, boron, molybdenum and manganese have all been shown to give significant yield improvements in particular situations. Read more

Interpretive Summary


Using data from regional soil tests, grain nutrient contents and a review of literature, the risk of plant micronutrient deficiencies (B, Cu, Mn, Mo, and Zn) was made across the Australian grains belt. The results indicate that the major micronutrient risk is from Zn deficiency and while Cu deficiency is not widely indicated, there are uncertainties about the risks associated with Cu. Future research should still focus on the deployment of these two micronutrients within cropping systems.


Australia has had a long history of investigation into micronutrient deficiency, including significant advances in nutrition of pastures, crops and animals. In the grain growing regions, there are reports of B, Cu, Mn, Mo, and Zn deficiencies as well as particular cases where Fe deficiency is seen.
