Growing Alafia is great for many reasons its a great food source for animals and people. Alfalfa sprouts are a great microgreen if your into microgreens.

Its a great cover crop for planting in-between crops to keep that soil alive by pumping plant exudates into the ground as well as feeding local wildlife like rabbits. Alfalfa is a nitrogen Fixing crop using Rhizobium nodules. Bringing down cost of fertilizer by fixing nitrogen from the air into the soil so you don’t have to apply as much or any fertizler when you have a complete permaculture system.

Then when you chop the cover crop it can be bailed up for storage for grazing animals during the winter months as well mulch.

Alfalfa normally has a NPK ratio of 3-1-2 a bit more or less depending on where it was grown and brand. So it has a little of everything but more Nitrogen great for young plants.

One of the most talked about properties of alfalfa is triacontanol which is a natural plant growth hormone. Which increases a plants effectiveness to photosynthesize and promotes roots and shoots. So alfalfa is great to use during the vegetative growth period with its high nitrogen content and natural plant growth hormones and trace minerals.
