Hemp? #14

Closed rugk closed 7 years ago

rugk commented 7 years ago

In some countries they are legal, as it seems.

Affects Hemp tow waste and Hempseed

westnordost commented 7 years ago

Why would it? There are cultivars which are not usable for THC production: https://de.wikipedia.org/wiki/Nutzhanf

The hemp (for hemp fibre) is being collected with trucks on farmland.

rugk commented 7 years ago

Questions are these:

westnordost commented 7 years ago

For fibre, the whole plants are harvested, there is nothing left.

rugk commented 7 years ago

Well… they can always grow the hemp on the same field again. That's the question… Or is that too unlikely? Does hemp need drop rotation?

Ah, just found something:

Since hemp is very self-compatible, it can also be grown several years in a row in the same fields (monoculture).

https://en.wikipedia.org/wiki/Hemp

So, we include it?

westnordost commented 7 years ago

Nothing needs crop rotation if you have fertilizer. That is not my point, my point is that the whole plant is harvested (with a tractor) and for me this makes a distinction between orchard and farmland. Tractors don't plow through coffee plantations, apple tree plantations, wine plantations etc., the fruits needs to be picked. For hemp, the whole plant is harvested (at least for fibre production), just like it is done for cereals, rice, sugar canes etc.

rugk commented 7 years ago

Okay, yeah. Then maybe we need to retag this to landuse=farmland, that's okay. But from satellite images it certainly can look like an orchard. That's the reason to include them.

westnordost commented 7 years ago

Really?

This does not look at all like a plantation, in my opinion. The hemp plants are harvested young I think, so they don't get that big as they could (like with cotton).

rugk commented 7 years ago

Well… we also included Sisal (and we excluded cotton BTW.) and coffee does look not that different IMHO. Both "plantationy", as you expressed it.

westnordost commented 7 years ago

We could also exclude sisal, really. It is the same thing as with hemp. They are both harvested fully for their fiber.

For the coffee pic: Really? In plantations where people pick the fruits, you always have these walkways. The video I linked does not have these walkways at all. (The distance between each row is something you see for every crop planted with a tractor, cereals, maize etc.)

Okay, okay, you've convinced me. It's like cereals (only a bit more green from satellite). It's clear that this is no orchard, but would need retagging and it should not be confused. So, exclude.
