Alfalfa Meal (AM) organic fertilizer is made from the
leguminous Alfalfa plant, that also fixes nitrogen in the soil. YES –
FREE nitrogen. Alfalfa is also an excellent cover crop (see cover
crops) or a permanent cover crop for orchards. Alfalfa has
the ability to send deep taproots down into the soil for increased soil
aeration and conditioning.

AM fertilizer is a decent source of nitrogen and a small
percentage of phosphorous and potassium. The major benefit of AM is its
affect on the soil’s
microorganisms. AM contains special microbes that activate
the soil’s microorganisms that in turn help convert soil
nutrients into soluble forms for the plant… an adrenalin
boost for your soil.
Another unique feature of AM fertilizer is a naturally
occurring compound called Triacontanol. Triacontanol is a growth
hormone that boosts plant growth. Its effect is short term and best
used as a tea on seedlings.
As animal-based fertilizers are coming under more scrutiny,
due to certain practices and disease susceptibility, AM will become in
important in the future as Nitrogen based fertilizer. Make sure that
the AM source is organic. If not, your AM may have pesticide residue.
