Not true. I have stated on numerous occasions that I support bridge programs as a means to an end .... the end being complete (or at least nearly so) removal of synthetics from landscape maintenance programs. That said, while I don't have a problem with very light chemical use from time to time, I do NOT support permanent bridge programs (like yours) in a typical landscape.

For the record, not all plant nutrients are salts (ex. carbon, oxygen), nor do all mineral nutrients necessarily come from the soil, even if that is the predominant reservoir..

Also not true, see biological weathering.

It states...


Mineral nutrients are also called IONS. Which are also called salt based fertilizers. Whay the heck would a microbe compete FOR an ion if it doesn't want/need it?
What does any of this have to do with microbes producing ions or the impacts of synthetic fertilizers on soils and soil biological communities? Furthermore, your assumption that all microbes can/do consume mineral salts (regardless of the source) is ignorant at best.

What is your point in quoting these passages? Neither Tim nor I have stated anything that contradicts what you have quoted. If this is the biology lesson you indicated Tim and I needed, you fell way short.

The issue here (and has always been) is your ignorant stance that chemical fertilizers cannot cause damage to soils (all inclusive) .... and your grossly over simplified and incorrect statement that salts don't kill microbes (therefore chemical fertilizers do not) is merely a display of your ignorance. It is irrelevant if some microbes use the very same ions in their biological processes .... that was never an issue here ... well except that you are trying to make it one. The issue with respect to soils (in general) is with short circuiting biological processes that build soils, reducing biological community diversity, excessive salt accumulation, and soil acidification, etc.... All of these can have wide ranging negative impacts on soil fertility and biology and plant health/yield.

I have posted numerous journal publications that demonstrate chemical fertilizers and pesticides can in fact lead to a net negative impact on soil biology, biological communities, and soil fertility. Nothing you have presented here, or in any other thread, disproves these studies. You have erected a straw man here, and like all straw men, they have no life or substance.
