You are assuming chemicals are bad for agriculture. This is not a valid assumption. There are good chemicals and bad chemicals. Please keep an open mind, do some in depth research. I'll give you one example of chemicals being good and one example of chemicals being bad.
The good: A farmer invests thousands of dollars planting a field of broccoli. The field becomes infested with cabbage looper. The farmer cannot sell broccoli that is damaged by cabbabe looper, so he sprays an insecticide (probably one that is harmless to people). The cabbage loopers die and the crop is saved. That's good for the farmer because he can sell his crop. It's good for you because you can buy undamaged broccoli at the store.
The bad: A cotton farmer has his cotton field attacked by cotton bollworms. He needs to spray to control the bollworms. He probably has to spray more than once. The spray kills the bollworms, but also kills insects that prey upon other cotton pests. This leads to an outbreak of whitefly, a secondary pest, which leads to sticky cotton which is hard to gin. That's bad. But it happens sometimes (emphasize "sometimes") in the real world. This type of situation causes the cotton farmer to weigh all the options before he sprays in the first place.

Stop talking about chemicals as if they are something bad . Know what u are dealing with.
HCL bad acid
caustic soda bad base
mix together to a PH of 7 what u have
Table salt and water.
Very few are bad for agriculture and with a lot of water the plants will be able to survive. A pin hole in an oil pipe line was stopped quickly and a light spray of petroleum covered our lawn. We watered well and the plants responded as if we had fertilized it.

It`s not the chemicals that are harmful, it`s the way they are used or abused
Just as a loaded gun on a table is nothing more than an inanimate object. But put in the wrong hands can cause untold grief and misery. Yet in the right hands can feed a family.

Nitrogen is harmful. to produce it artificially we have to expend great amounts of hydrocarbon fuel to create, transport, spread, and mitigate unintended impacts. we waste oil on growing corn we cannot use in cars.

The abuse of chemicals are the problem here.
