In The need for agronomists in the future: Will technology take over? (14 August 2015), available at https://www.fginsight.com/vip/vip/the-need-for-agronomists-in-the-future-will-technology-take-over-5493, Farmers Guardian reports on trends that will fundamentally impact on the role of an agronomist:
20 years from now every new variety will be genetically engineered, so an understanding of crop genetics will be important.
Most crops, including wheat, are likely to be hybrids. That will require a fundamental change in the way crops are grown including different seed rates and inputs.
There will be a convergence of genetics and chemistry. Chemical interventions will interact with the genetics of the crop to prevent and control the development of weeds, pests and diseases.
A convergence of conventional and organic techniques. [Beyond] relying on just chemical solutions, ... agronomists ... need to have a deep understanding of fundamental agricultural principles with a robust rotation at the heart of the system.
More emphasis on soil, water, and environmental management both to protect the environment and resources, but also to ensure efficient crop performance.
Ideas for new research can be gleaned from these five trends.
In terms of results, I suggest reviewing foresight study of Agroindustrial Engineering, although in 2018 a new foresight project to 2035 will be started in this area with the help of LACCEI and the competitiveness, technology and innovation section of OAS.
