Learn Something Today: Small Scale No Till Farming...Building Soil From A to Z!

What happens here

In a field previously terminated and planted, the hosts examine the soil beneath the cover crop mat. They locate a decomposing daikon radish (also called tillage radish) tuber, explaining its role in aerating the soil by burrowing deep (1-2 feet) and creating channels for water infiltration. Radishes also break up compacted soil and store nutrients that are released upon decomposition. Digging deeper, they reveal numerous earthworms, which are crucial indicators of healthy soil, further enhancing aeration and nutrient cycling. The soil profile shows a rich, dark topsoil layer transitioning to red clay, demonstrating the successful long-term soil building process.

Goal: Observe the impact of daikon radishes on soil structure and nutrient cycling, and confirm the presence of active earthworms as indicators of improved soil health.

Tools and materials

  • Shovel
  • Daikon/Tillage Radishes (decomposing)
  • Earthworms

What they say

Hide

anywhere from a foot to two feet deep and they're normally about 2 to 3 inches in diameter it holds a lot of nutrients in that tuber that it has and that's the reason that I plant it and it also breaks up the soil because that thing is going down in the ground and driving this soil apart enabling the water to go down into the ground as it decays and breaks down if you look real close right here was talking about no tilling beans and stuff inside of here basically what it does it'll come through here and cut a trench a real small slit the one double disc opener will open up the ground places the seed in and you can see real close right here you see we got a seed here coming up see you here seed here so forth and so on and then right beside of this seeds right here is gonna be our tuber as this breaks down it really does think though that's the only bad thing that I don't like about radishes as they real they smell terrible so you're saying these are called daikon radishes right or killers radishes okay okay and they will burrow down to a foot foot and a half yep okay and they provide a nutrient for the soil they rot they also aerate the soil and provide nutrients for worms and microbes - that's right just let all those nutrients go right back into that top layer so where all these see all these seeds are coming up - cool so the no-till drill doesn't tell but the radish pills for you and gets the nutrients down deeper into the soil oh yeah I like - oh yeah right here the other beneficial thing that I like about no tilling and cover crops and always having you know something on the landfill you know the worms and the fun guys all kinds of microorganisms to eat is this right here when we go to a field and you can take a shovel and find earthworms you know by the handfuls and you can look at each you can look at the profile of a soil you got your red clay right here and you've got this is the top layer which we've been working on and this is what we're striving for to get this brown lomi dirt to keep building organic matter because it's just gonna get deeper and deeper and it's real easy to plant in - once you get it to this stage you can go through here with just a set of double disc opener you don't even have to have a set of cultures on the front of the planter you can see all these little passages and stuff where the worms have been before and all that is is the passage for the rain to filter down into the land it won't get to this it won't get to this clay…
