Here’s a good resource that explains “plant-available nitrogen levels from a good stand of legumes peaks at the budding growth stage and declines as growth continues” so farmers should “wait until bud stage to terminate legumes.”


The article also notes, “Where most of the legume nitrogen fixation comes into fruition is in the spring, but a lot of farmers don’t leave them long enough. They would need to grow ‘till mid-May or the end of May. If you’re going to kill it in late April, you’re probably not going to get much of it.”

When legume goes into reproduction it will start to use N reserves from nodules and for annuals will increase C:N ratio.
