Alfalfa meal or pellets is one of the green manure crops and
contains small amounts of nitrogen, phosphorous and potassium which
feed the plant. However, the biggest benefit of alfalfa is from the
work it does in the soil. Alfalfa contains the hormone, Triacontanol,
a plant growth regulator. Alfalfa meal can be top dressed and watered
in. But quicker benefits are had when alfalfa is brewed into a tea.
The primary boost comes from the millions of microbes in the fermented
meal that activate the soil organisms that then convert nutrients into
forms available to plants. Roses love it. Only apply alfalfa to the
surface. If placed in the root zone, the rapid decomposition of
alfalfa will generate heat which can damage the roots.



Is the alfalfa meal substantially better than alfalfa which has gone
through a cow's digestion (manure)?
