Tim Worstall uses an article in the Guardian about a National Trust experimental replication of medieval farming patterns to point out exactly why modern farms do not use them:
Plan of a fictional medieval manor. The mustard-coloured areas are part of the demesne (owned by the lord), the hatched areas part of the glebe (reserved to support the parish priest).

The proof of the inefficiency is in the presence of that lots more wildlife. We’re trying to grow food for humans to eat recall. So, more wildlife eating off the same earth is less food for humans. We have more butterflies around? That’s nice, but that does mean more caterpillars munching on those now not for humans crops. Hen harriers? Great, but they’re eating the mice and the voles living off those crops. Land that’s growing wildflowers isn’t growing grain or veggies for us, is it?
Sure, it’s nice to have hen harriers, great to have wildflowers. But their very existence on this land shows that this method of farming is less efficient at doing the job of farming – growing food for us. Which is why we abandoned this method of farming of course. Under the simple and basic pressures of trying to gain more output from our inputs. And yes, land is, obviously enough, an input into farming.
And if we’d like to have flowers and harriers? Then we should be using the most efficient farming methods on those areas we do farm so as to leave more space, more land, for the pretty things we’d also like to have. That is, prairies of glycophosphate drenched wheat for us, the other 30 or 50 or 70% of the land left alone for them. And the more chemicals we use on our bit the smaller that bit devoted to us is going to be.
The very fact that we’ve more wildlife as a result of this inefficient farming method shows us that we must be using the more efficient industrial methods. You know, to save the wildlife?
