Before you read this and get the wrong idea, I do a lot of no till. the tilling I refer to is for a medium sized annual garden.
I did a search of the site and came up with nothing on tillage radish. It's just a big Dicon radish used for growing corn in no till crop rotations (usually using herbicide). Anyway it puts a lot or carbon
in the soil in a really fast way and it dies in winters with frost -6 or lower thus decomposing and releasing nitrogen and other nutrients at the correct time for the corn (or other annuals).
Anyway today I tilled up a patch of daffodils to use as an annual garden and I started thinking hey here's a plant that can be left in the ground for longer periods collecting carbon and nutrients which can be tilled up and used any time of the year (I grow alot
of onions and other fall and spring active plants and tillage radishes may work for fall if tilled in early summer but are not so good for the spring season). So lots of plants store up carbon in the soil, some are weedy (sunchokes, comfrey) and re-sprout setting back the crop you wish to grow. Others Are more difficult to grow or have a higher value, like potatoes (you wouldn't just till up your spuds). So what we need are tuberous plants that do not re-sprout when tilled, are not costly and can (A)die off, or (B) be tilled under, at different times of the year depending on the crop we wish to grow off of their dead bodies. I wish I could find a tuberous plant that would just die off like the radish but I want it to die in august (when it gets really dry) so it will be decomposed by spring.
In conclusion I guess I could just till some radishes under in august and plant the dormant bulbs directly in to the area this would deprive the bulbs of nitrogen in the fall but in spring they would get a good boost
. Man typing this out really helps my poor brain to think
Diversified Food forest maker . Fill every niche and you'll have less weeds (the weeds are the crop too). Fruit, greens, wild harvest, and nuts as staple. Food processing and preservation are key to self self-sufficiency. Never eat a plant without posetive identification and/or consulting an expert.
