Highly related, but never resolved: Is agriculture on topic?
The site has had several agriculture-related questions of late, the vast majority of which have been closed as off-topic. The most recent question related to agriculture asked [What is the real impact of Precision Agriculture? This question has been closed as off-topic. It is this question that has caused me to write this meta question.
There is absolutely nothing in the official site documentation that indicates that questions related to agriculture are off-topic. To the contrary, the site has an agriculture tag has a usage guidance, but no details. The usage guidance says agriculture is
The cultivation of food and materials, specifically from or derived from plants and animals using traditional or modern industrial practices.
That strongly implies, at least to me, that all of agriculture is on topic at this site. Given that, the basis for closing the recent spate of agriculture questions is (at least to me) dubious. This is not like the recent "let's stop identifying rocks" debate. Those rock questions were of very limited applicability. Questions about agriculture can have a much wider applicability than can even the best rock ID question.
That said, there are reasons that we might want to continue to close questions related to agriculture.
Questions on agriculture are even more boring than are questions about rock identification. Note very well: I wrote the above with my tongue deeply impaled in my cheek.
There are other stackexchange sites that can answer some questions related to agriculture. The Sustainable Living and Gardening & Landscaping SE sites certainly have some overlap with regard to agriculture; the former even has an agriculture tag. Perhaps more surprising, the Geographic Information Systems also addresses some agricultural questions; this site also has an agriculture tag. Of particular interest is that the GIS SE site has a number of questions (with answers!) regarding precision agriculture.
We don't have the expertise to answer such questions. This might well be the real reason. If that is the case, we should admit this short falling. But note very well: Taking this route is a self-fulfilling prophecy.
Regardless of the outcome of the discussion, the agriculture tag is in need of refinement. The refinement is simple if the end result of this discussion is that all questions related to agriculture are off-topic.
If the decision is that some questions related to agriculture are on-topic but others are off-topic, good luck coming up with a rationale. Whether a question related to agriculture is left open or has been closed as off-topic has been highly capricious. Closing a question as off topic that integrates multiple aspects of the Earth Sciences (which is exactly what precision agriculture does) seems a bit ... odd.
