I think most folks will tell you there is a difference in flavor, Gary, but that is subjective, so let's leave that one lie...I notice a difference in my garden the yield goes up and vegatables taste just as good with fertilizer, no change in flavor. I have a very small garden I don't care if it does cost extra for fertilizer food is better that grocery store food and I get more food per square foot. Without fertilizer I would have to plant a larger garden and do more labor to do what the smaller garden does with fertilizer.
You are tilling and adding fertillizer, right? Any composts at all? Not in most agriculture, just tilling and chems... we are both adding ammonia, but you as a salt with your fertilizer, and mine as protein with biology in the compost. Mine actually adds life and biodiversity; you are killing it by osmotic shock with your salt, so there's a difference in our ammonias, a big one.
Mine is incredibly stable as it actually doesn't turn into ammonia until somebody eats my biology and releases it as ammonia; yours is unstable three different ways (It is soluble in water, it can volatize and gas off, especially at high temperature, and it can get locked back up in biology without the right biology to unlock it). So there's another HUGE difference in our ammonias.
My biology maintains the soil structure, adding humus and building biological structure while your fertilizer disrupts the fungal net that adds glomalin, the magic glue that holds soil in aggregation. You till and destroy fungal while I build soil. Notice the area you have been gardening like this is sinking deeper than where it used to be; you are compacting soils, decreasing root mass and hobbling nutrient uptake. And my biologically diverse soil allows biologically diverse planting; as toil noted I will add at least fifty percent to my yield this year (tomatoes doubled, another 30% peppers, twice the squash and three times the greens! And I still have space this way! Bok choy maybe; I'm waffling). I will totally bring in more crops in less space than any two of my MG using neighbors combined, guaranteed...
No, my friend you are completely off base there. Our ammonias couldn't be more different. Your's pollutes before it even gets in the bag; mine is utilizing local waste streams. We aren't even in the same zip code, our ammonias... but toxic? Not in the food, per se, but it is [url=https://www.bfhd.wa.gov/info/nitrate-nitrite.php]toxic to humans in drinking water[/url], not that that will take long to get there... oh, and the higher levels you need (because you don't use biology that clings to the plants roots like I do) cause bigger releases of ammonia which turn into bigger quantities of nitrite in the water, and if [url=https://www.preventcancer.com/consumers/food/hotdogs.htm]it ain't good in hot dogs[/url], it probably ain't good in water. Mine does that too, but because it releases organically in MUCH smaller quantities right near the root it is living with, most gets used before there is any chance of getting to water... and my increased humus means more Cation Exchange Capacity to hold those nutrients in soil stably, so even if the plant doesn't get it my soil will, instead of the water...
Our ammonias aren't even in the same state. Literally.
