Ya know, I've been thinking I should write an article about "Nitrogen Fixing Plants." I will work on that
Although much of the nitrogen in legumes is stored in their roots, some does make it's way into the soil while they are growing, and will help fix the soil to some degree. But when they die back, their decomposition releases the stored nitrogen. That's why it's good to plant a winter crop of legumes, clover, or winter peas; in the spring you can till under the plants to decompose and raise the nitrogen for availability to your spring plants.
I'll let you know if I need help figuring out how to do an article LOL
hahaha
