Grat3fulh3ad said:...That the hydrogen used to make amonia may be hydrogen that is a byproduct of the pertoleum industry is irrelevant, that hydrogen is already going to end up in the environment somewhere... Calling it a petrochemical derived nutrient is just a propaganda word, since a large portion of the water molecules in the world came from burning hydrogen which has been released from natural gas or other carbon compounds which could also be called petrochemical...
I wonder if water bottles need to be labeled as potentially containing petrochemical derived water....
Oh hell... isn't water also an inorganic comound?
Grat,
the extractions of elements derived from petroleum are done by man, obviously. so for nitrogen molecules derived from petro-chemicals
to reach the plant needs to first go through what is termed an artificial and unnatural process, that is, the potential elements that can be obtained from petro-chemicals are only obtained through man´s intervention. in contrast, the nitrogen molecules that a plant needs and are derived from a natural and spontaneous process of organic decomposition will always be in effect without the intervention of man, plants have always fed themselves through this process. so that nitrogen molecule derived from petroleum won´t end up in the environment somewhere without man´s intervention, if you leave it to nature, it will keep that nitrogen molecule doing its thing in the petroleum below ground :wink:
this are things to be considered when thinking of what is known as organic/sustainable gardening/agriculture, as other posters have pointed out before, it is not really a question of who uses what nutes or growing method, but rather, how each gardener relates to the environment in which he/she works; in these things are subtle differences, which for some people, myself included, are important to work with and give them their proper relevance.
whether we like it or not, the term petro-chemical relates to all chemicals (this word has no negative connotations btw) obtained and derived from petroleum/gas. there is no conspiracy going on to make people using synthetics feel guilty or anything like that.
peace!
