Re: New City Grower
What else would you suggest that plants eat?
They have to get their nitrogen and hydrogen from somewhere
and nitrates are usually where they get them from.
That's why we like soil bacteria :
Nitrification
this is a cycle. the minerals are from the sky and in the earth. the plants convert these raw harsh minerals into plant tissue, which feeds the animals. when we feed our plants we either want raw minerals from the earth, or better yet, animal/plant waste that's already processed these raw harsh minerals chemicals (manure, fish emulsion, emulsified sea kelp, molasses from beets etc.)
then we have companies that synthesize fake minerals which are made of plastic and other garbage. this was not originally part of the cycle and theyre very nasty. if these companies went out and harvested minerals from the earth it would be better, but we know they don't do that because that's more expensive.
for example, many companies use urea as their main nitrogen source.
Urea-formaldehyde, also known as urea-methanal, named so for its common synthesis pathway and overall structure,[1] is a non-transparent thermosetting resin or
plastic, made from urea and formaldehyde heated in the presence of a mild base such as ammonia or pyridine. These resins are used in
adhesives, finishes, MDF, and molded objects.
It was first synthesized in 1884 by Hölzer, who was working with Bernhard Tollens.[2] In 1919, Hanns John (1891–1942) of Prague, Czechoslovakia obtained the first patent for urea-formaldehyde resin.[3]
"Urea formaldehyde is also used in agriculture as a controlled release source of nitrogen fertilizer. Urea formaldehyde’s rate of decomposition into CO2 and NH3 is determined by the action of microbes found naturally in most soils. The activity of these microbes, and, therefore, the rate of nitrogen release, is temperature dependent. The optimum temperature for microbe activity is approximately 70-90 °F (approx 20-30°C)."
sure it makes the plant green and looks like its on steroids, but do I really want buds made of plastic? that just spells disease and not to mention harsh smoke. im surpised the soil life or biota even learned how to breakdown plastic. I hear fungus can even eat plastic nowadays (like on a plastic shower curtain)
