However, I find the books are limited in their approach. It is usually very simple stuff like this

Firstly, they take no account of the fact that the area required for different "groups" are different.
Secondly, they focus on summer crops, almost to exclusion and don't explain how to use the ground best over the whole year. (For example, I lifted my onions in July but my beans are still cropping well and the main crop spuds are still in the ground so the winter brasicas have gone into the space which had the onions).
I know that quite a lot of ground will lie unused over the winter just soaking in the manure but if there is any helpful guidance on how to use the ground well (for example, as the broad beans are gone, what should go there - I'd need more space than the broad beans occupied for the brassicas just mentioned)
Thanks
