Repairing the Ozone Layer

"The ozone hole recovery at this stage, 34% of that recovery, is just due to the regulation of methyl bromide." Prof. Ian Porter

As a child of the 80's and 90's, I vividly remember the discussion around the hole in the ozone layer, a real hot topic of the time.  Professor Ian Porter of La Trobe University has been working with the United Nations since the Montreal Protocol was enacted to aid in its repair.  Ian's role has been to co-chair the committee for the reduction of Methyl Bromide in Agriculture. This work, along with the reduction of other ozone depleting substances,  has resulted in significant repair to the ozone layer and the atmospheres ability to filter ultraviolet radiation. 

We discuss soil health, UV radiation, leadership and the politics of working with the UN. Ian is passionate about this topic, hence his recent award of recognition from the United nations for 30 years of dedication to the cause, and a great communicator. 




The Soil Health Lab.

Dirt Dude Conversations 1. Bob and Kirsten of the Soil Health Lab.

"Cover crops, I think that's gotta be one of the most important things,just because of building up the organic matter, and reducing the erosion potential." Kirsten Kurtz

Bob Schindelbeck and Kirsten Kurtz of the Cornell University soil health lab are soil analysis and extension experts, connecting farmers with the latest thinking at the University. The soil health movement is a relatively new way of thinking to mainstream agriculture, and Cornell has worked hard at a holistic approach for measuring and then delivering tools to improve soil health and agricultural sustainability. Often is as much as understanding the motivation of the farmer as the soil tests themselves.  It was with Bob and Kirsten that I first realised that soil science is as much about the sociology as the science.

We talk not only about the soil health Lab, but also growing wine grapes in the nearby Finger Lakes district, the importance of cover crops and reducing tillage. These guys are seriously passionate about their soils and serving their districts.
