Crop Rotation/Polyculture

I've been reading conflicting sources on whether crop rotation or polyculture is preferable for gardening, so first of all I'd like to know what's your input on the topic.

Secondly, trying to sort of mix the two approaches, I devised the following scheme for my garden beds, would you say it's decent enough? Is a two-year rotation enough for producing benefits?

Year 1
Fabaceae
Solanaceae
Poaceae
Allium

Year 2
Umbeliferae
Amaranthacea
Brassica
Leafy Greens

Perennials have a bed of their own and the rest can be planted according to companion planting guides.

I think crop rotation to start with until you have more of a polyculture established. I think if you want to sell your veggies crop rotation with rows is still more efficient but you can still have a polyculture within your rows, over time the goal is to encourage the weeds you like while pulling the ones you don't want in your polyculture. I will be experimenting with various living mulch next season. I thought I would chip in since no one said anything but still learning over here...

Monoculture is all about making easier to cultivate/weed and harvest, not what is best for the soil or crop. Crop rotation is a compromise to kill the soil slower.

Olá Luiz... my experience confirms what Miguel said... rotation in the beginning until things get established later. Reason for that? Simple. Pests! If you keep the same culture in the same place the pests will never go away until something defeats them... could be the weather change with a different season, could be you removing your crop to cut their food source, etc... If your crop gets hit by a pest it is going to be a daily headache... better to rotate crops to constantly keep the pests on check... eventually you will find the best place to keep the same crop on a constant basis with the best results.
