Description

The first phase of the project involved a literature review, a survey of organic grain producers, and an analysis of historical yield and climate data in order to document the effects of climate extremes on yields and soil nutrient availability. The ultimate objective is to develop cropping scenarios or agricultural practices to be tested under experimental conditions and on farms and to a funding request to ensure the continuation of the project.

Objective(s)

  • Evaluate how climate extremes affect the availability of soil nutrients (mainly nitrogen) in organically grown field crops
  • Develop agricultural practices to correct or mitigate these effects.
  • Develop a research protocol based on a survey and analysis of historical data to compare climate extreme mitigation measures in experimental-plot and on-farm tests.
