you didn't provide data, chemical based farming has been going on industrial scale for 100 years now... no barren land is accumulating.
if 100 years aren't enough to evaluate long term consequences what is?

100 years isn't long when you're changing the global ecosystem.
The Industrial Revolution began in the late 1700s. We're only now beginning to agree on its long-term consequences, and quite a ways off from agreeing on mitigation steps.
What is data? In the comment I replied to, the words "rather than" indicate that the OP considered the defense "natural vs. unnatural" to be a defense based on data. I replied on that standard.
I will repeat that I hope Sri Lanka continues this experiment. Experiments like this are the only way we'll get the data we need.
