What happens here

The host digs up the roots of a legume (winter pea) to showcase the visible nodules, explaining that these are sites of atmospheric nitrogen fixation. He clarifies that this fixed nitrogen is stored within the plant and will be released into the soil when the plant decomposes. He then simulates the termination process using a roller crimper. This method involves pushing the cover crop over and crimping its stems every 5 inches, effectively killing the plant without disturbing the soil. This creates a dense, protective mat on the soil surface.

Goal: Examine the roots of legumes for nitrogen-fixing nodules and demonstrate how a roller crimper terminates cover crops to release these stored nutrients and create a protective mulch layer.

Tools and materials

  • Shovel
  • Legume Cover Crop

decide to plant this alright so what we want to do now is we want to talk about nodulation on all the legumes that I plant a lot of times what would do is when when they start blooming as you can see these are in full bloom right now there's actually peas and pods on them that tells me that it's time to to terminate the crop and the way we do that here is a we do a roller crimper method which is basically a great big drum that rolls over and crimps every five inches of the stem which will actually kill that plant I want to talk about a little bit about nodulation on all these legumes alright so what we did all we did was we we dug up some roots and you can see all those little nodules and each one of those is atmospheric nitrogen that come out of there the plant took it up and stored it in the root system that's what those little green dots can you touch him yeah green dots right there oh yeah dad that's nitrogen fixation that's exactly right and what that's doing when we after we roll this crop we will this nitrogen will be right here on top of the surface getting ready to be absorbed by the new crop that we're gonna put in so your corn or your soybeans will be ready to just suck it up and take off we're going to just basically simulate just taking a roller crimper and doing it and basically all of the all we're gonna do is we want to step it step over the crop push it over and then step on the stems so you want it to all go one way just like this right here and then that's going to good right there yeah and then what you've got you've got a
