This and That
Food for Thought
Algae,
yes algae, although not fully explored may be the food of the future.
It is estimated that the total amount of photosynthesis carried on by marine
algae is ten times greater than the total of all land plants.
Alfalfa
(Medicago sativa) is one of the most powerful nitrogen-fixers
of all legumes. A good stand can take 250 pounds of nitrogen per acre from
the air each year. Alfalfa needs a deep soil without a hardpan or an
underlying rock layer, because it sends it roots down very deep.
Researchers have traced them well over 100 feet and 20 to 30 feet is average.
Alfalfa's
deep-rooting ability is the source of its great nutritional power, feeding as it
does from mineral rich subsoil which has not been worn out and depleted.
It is strong in iron and is also a good source of phosphorus.
So
Why Do We Hate Dandelions?
Earthworms
like the soil around dandelions for this plant is a natural humus
producer. You may not like them in your lawn but they are really not in
competition with the grass because of their 3 foot deep roots. They bring up
minerals especially calcium. When dandelions die their root channels act
like elevator shafts for earthworms.
