Definition in lead

I altered the lead as it did not actually say what threefield rotation actually is. But I'm now not sure I got the definition right, particularly whether it takes three years for a full rotation. I will not alter it further, but hope someone who knows more can take a look. LastDodo (talk) 13:49, 25 November 2021 (UTC)[reply]

Okay so as it stands the lead is correct. The only useful additional piece of information the definition could benefit from is the fact that in medieval Europe at least, the crop was first a winter crop, then a crop sown in the spring (then left fallow in the third year). I do not know whether this was universal or not, so have not added it. LastDodo (talk) 11:21, 7 January 2022 (UTC)[reply]

Three Field System in China

Joseph Needham in his book Science and Civilisation in China (1984, Needham and Bray - also published in China Quarterly) only speaks of different forms of rotation systems, but not specifically of a Three Field System.--213.142.96.106 (talk) 17:03, 16 November 2022 (UTC)[reply]

Needham refers to a "two- and three-course crop rotations similar to those of medieval Europe" by the Eastern Zhou. A google search turns up nothing for three-course crop rotation, so unless there is another form of three-field system existent during the medieval period, then this is likely what Needham is referring to.
