@Organikz " You toast the micro herd as soon as you add nitrates"........show me the science behind that statement because its bullshit period...
Here is the basics of nitrogen

Here is a study between synthetic and organic ferts and there affects

Bacteria do not know what is organic what is synthetic and neither does the plant. The differance between synthetic and a animal by product aka organic fert is the carbon content. Also animal by products are a slow release version of fert typically, where synthetics do not need to go through a conversion proces to be viable for use by the plant.
Its like saying that if you use any inorganic substance to grow a organic crop with it is no longer organic. Again that is a false statement because there are inorganic substances vital to sustaining life of that crop, yet everyone uses it and still states thier crop is organic.
Bacteria have to have nitrogen to live. Yes you can kill bacteria by going to toxic levels, guano and chiken manure are 2 good examples and yes if you use anhydrous ammonia you will kill the bacteria for a breif period.
If you use your inputs responsibly you will not kill the bacteria herds reguardless what you choose to use as a input.
The only reason I replied is to stop the misinformation being given out. To the op did not mean to derail the thread but I am trying to get the facts out in the open where they belong.
