It all depends on the type of land the field is made from. Some farmers dont plough at all.
In times gone by, apparently, most crops were planted in the spring as they wouldnt take a frost. Generally in autumn-time, oilseed rape and cereals (wheat, barley, rye, oats, "the ones like grasses") are planted. In spring we drill crops that do not tollerate the frost (peas, most beans, linseeds, sugar beets, etc).
Crops dont need to be rotated nowerdays. Or rather some dont. The "Broadbalk" experiement has been growing just wheat for a very long time - since 1843. Grass also can be grass for ever ;)
I'm sure if you asked the farmer, s/he would be happy to talk to you about it, and of course, there is Open Farm Sunday.
Take the dough and stay real jiggy.
Uh-huh.
