Digging Our Heels Into Hardened Soil

 Ya know how when Trump first garnered attention as a wild card in the various races to become President and everyone thought he might tone it down once at the top? And then once he was president, with each passing day, we continued to be surprised, and then slowly not at all surprised that he continued to act a bit unhinged and certainly unlike any politician seen or heard before? And next thing we knew, nothing could surprise us and we hardly lifted our heads at the latest headlines, hardly gave his antics much attention at all?

I'm worried I may have arrived at that point with genetic science in agricultural crops. I'm almost not even surprised when even the craziest research has been funded and the latest 'solution' developed, suddenly staring at me from my computer screen, from a CBC Quirks & Quarks article no less. 


Go on. It's not a terribly long article, you've got time to give it a quick perusal. (If you REALLY don't, the Cole's Notes is that plants do not do well in compacted soil -surprise!- and scientists have identified one reason this might be; ethylene, which does not diffuse through compacted soil. Fear not young reader, genetic modification is here and will create plants who ignore the ethylene and literally punch through the hard soil.)

I almost, for a second, thought it was a joke. Perhaps there's now The Manatee or The Beaverton for farming?  No, the linked scientific journal would suggest otherwise. 

I'm finding it difficult to form my thoughts coherently around this topic and yet I've been sitting with it for several days now. Rather than bore you with a long article outlining my dismay, here's some bullet points instead.
  • Isn't the most important thing we know about soil at the moment, that we know so very little about soil? Is it possible that this one, singular conclusion about ethylene is missing some other important pieces about how compaction affects the soil biology AROUND the plant and not just the plant alone?
  • Are we now accepting that soil compaction is simply a necessity of our food production system? That rather than researching better technologies to reduce compaction, we're throwing money at genetically modified crops to better muscle their way through rock?
  • Is it conspiracy theory to suppose that the same companies that sell the chemicals and fertilizers needed to grow these crops that require heavy, compacting equipment, might also hold the patents for the specialized crops that can grow in those conditions? 
  • Has every consideration been made for how stopping the plant from detecting ethylene might affect the rest of its life, or the life of the soil biology around it, or the animals/humans who might consume it? Are there other roles that the ethylene plays in the soil and in the air that might be altered by mucking about with the plants' detection of it?
I've mentioned before that many years ago I had seriously considered creating a blog entirely about the silliness of various "solutions" created in agriculture that are in fact just treatments for the symptom. This could be the textbook example to beat all examples. Rather than treating the problem of compaction (huge equipment, short rotations, lack of cover crops, lack of organic matter, erosion, a focus on building soil and encouraging soil biology, etc. etc.), let's turn our attention to how we can fix the symptom (plants struggling to emerge in compacted soil). 

Can you hear that?

 It's my head banging against the wall.  

Please agriculture. Read the room. We need to move in another direction, not dig in our heels.

  1. I just came across your blog, and wanted to drop you a note telling you how impressed I was with the information you have posted here. I'm a trader, so I want share with you all on here on how I got my loan from a professional loan lender who works with a reputable loan company and they granted me a loan of 450,000.00 Euro to finance my business with 2% rate interest return so I want anyone here to know about Mr Pedro loan professional loan officer just in case you need a financial help then you can contact Mr Pedro Email on pedroloanss@gmail.com! Keep up the great work, you are providing a great resource on the Internet here!
