Tangentially related, I want a dataset of all cultivated lands and what crops they are growing? Is there a dataset for it? I mean, I give GPS coordinates and I get back crops growing there.

You want the Cropland Data Layer from USDA/NASS. 30m resolution, updated yearly:

General data is in government reports. The farmer who owns that GPS coordinate has it, but considers it sensitive data and won't tell you. There are big databases, but they respect the farmers not wanting to share and won't talk. The admins of those database are registered with the SEC as having inside information and so they cannot trade in relavent markets.

Interesting. I can't imagine it being so sensitive. Someone can look at satellite imagery and figure out what those crops are, even on a country wide scale.
