David is a genius. I listened to him speak for 4 hours at a conference in Ontario. I have 30 plus years of notill and 10 with covers but I know nothing compared to him. He showed his farm, a sea of green surrounded by his brownfield neighbours. They have one of the world's best right beside them and do not do it his way.

It ain't much, but it's honest work.

You made a stop at kansas years ago.where was it. It was so long ago I nearly forgot your stylish delivery. 'Ya know?"

And you're flying now too with grandson. Great presentation GABE..!!! and grandson too!

Excellent presentation

The math involved with determining nitrogen sequestration by a cover crop has a few variables, cover crop growth per acre, plant maturity at time of killing frost event. In my operation I need to be more precise with all aspects of my soil fertility. $11 seed for covers plus the additional cost of planting them along with the risk I take of the actual crop being planted late due to decreased soil temperatures in the spring. I like harvesting fertility from the air, so this tickles my fancy. My clearest opportunity to utilize the covers would give me about 60 days of growth window, but to avoid bankruptcy I would need to work the ground in the late fall, before my ground freezes.

Question: are the nutrients around the radish holes deposited by the radishes just being grown, or is that what gets deposited if the radish is left there to rot and then that's what the soil reads when its rotted/decomposed? What I am asking is can I harvest the radishes or do I have to let them grow then rot and get eaten by worms in that spot to get that reading of nutrients.

my boyfriend would really like to talk with david about his farm and cover crops, is there any way to contact him?
