Episode 226. We Need a Regeneration Revolution

This is the World Organic News for the week ending 11th of  August 2020.

Jon Moore reporting!

Decarbonise the air, recarbonise the soil!

Soil

Today we’re going to discuss regeneration in particular regeneration of the soil and ecosystems. Over the last 50 to 75 years, basically since the second world war we’ve gone through a period of destruction. In effect a faustian bargain in which we gave up 1% of our topsoil every year in return for production returns.

Industrial Agriculture

We did this by using chemicals: chemical fertilizers, chemical pesticides and herbicides and fungicides and it worked. There were lots of famines and people starving in the 1970s. A lot of the techniques developed with chemical inputs saved many people, kept them alive. But the cost! That bill is coming due and we need to pay for it now. If we wait, the cost will be so much higher. Continue reading →

Episode 219. Unintended Consequences of the Wrong Target

This is the World Organic News for the week ending 22nd of  June 2020.

Jon Moore reporting!

Decarbonise the air, recarbonise the soil!

The trouble with “knowing” is it leads to certainty, certainty leads to errors and these errors usually come from the unintended consequences of “knowing”. It may well be part of the human condition, it is certainly part of the current industrial agricultural paradigm.

From Dr Christine Jones’s last episode came the following:

Quote:

No amount of NPK fertiliser can compensate for compacted, lifeless soil with low wettability and low water-holding capacity. Indeed, adding more chemical fertiliser often makes things worse. This is particularly so for inorganic nitrogen (N) and inorganic phosphorus (P). An often overlooked consequence of the application of high rates of N and P is that plants no longer need to channel liquid carbon to soil microbial communities in order to obtain these essential elements. Reduced carbon flow has a negative impact on soil aggregation – as well as limiting the energy available to the microbes involved in the acquisition of important minerals and trace elements. Lack of trace elements increases the susceptibility of plants and animals to pests and diseases.
