I had an interesting conversation with someone the other night about organic gardening. He maintained that the animal manures we can purchase (eg, cow, sheep, poultry) are not truly organic products because of the hormones and/or antibiotics the animals are fed.
However, most advocates of domestic organic food production seem to use them, as I'm sure do most of us. The person I was talking to said that he considered the only "organic" fertilisers commonly available to home gardeners were fish emulsion, seaweed extract and home-made compost.
Granted, the fish emulsion and seaweed extract probably are "organic", but we know our oceans and waterways are often polluted and are therefore contaminants will most likely be present in the fish and the seaweed. As for compost, how many of us manage to have the only components in our compost fully "organic"? For example, I add shredded paper to mine, which I would almost guarantee is not totally "organic".
Which leads me to wonder about the time it might take for "non-organic" components to break down to the point of being relatively harmless. If this break down does occur within a reasonable period of time, maybe the manures we buy are OK, as they tend to be heat composted.
Would love to hear your thoughts on this.
