. The surviving ridges are parallel, ranging from 3 to 22 yd (2.7 to 20.1 m) apart and up to 24 inches (61 cm) tall – they were much taller when in use. Older examples are often curved.

Ridge and furrow topography was a result of ploughing with non-reversible ploughs on the same strip of land each year. It is visible on land that was ploughed in the Middle Ages, but which has not been ploughed since then. No actively ploughed ridge and furrow survives.

Origin

Traditional ploughs turn the soil over in one direction, to the right (see Single-sided ploughing). This means that the plough cannot return along the same furrow. Instead, ploughing is done in a clockwise direction around a long rectangular strip (a land). After ploughing one of the long sides of the strip, the plough is removed from the ground, moved across the unploughed headland (the short end of the strip), then put back in the ground to work back down the other long side of the strip. The width of the ploughed strip is fairly narrow, to avoid having to drag the plough too far across the headland.

This process has the effect of moving the soil in each half of the strip one furrow's-width towards the centre line.

In the Middle Ages each strip was managed by one small family, within large common fields (see strip cultivation), and the location of the ploughing was the same each year. The movement of soil year after year gradually built the centre of the strip up into a ridge, leaving a dip, or "furrow" between each ridge (note that this use of "furrow" is different from that for the furrow left by each pass of the plough). The building up of a ridge was called filling or gathering, and was sometimes done before ploughing began. It is thought that the raised ridges offered better drainage (on some well-drained soils the fields were left flat). The dip often marked the boundary between plots. Although they varied, strips would traditionally be a furlong
Furlong
A furlong is a measure of distance in imperial units and U.S. customary units equal to one-eighth of a mile, equivalent to 220 yards, 660 feet, 40 rods, or 10 chains. The exact value of the furlong varies slightly among English-speaking countries....

 wide (22 yards, about 20 metres), giving an area of from 0.25 to 1 acre (0.1011715 to 0.404686 ha).

In most places ploughing continued over the centuries, and later methods removed the ridge and furrow pattern. However, in some cases the land became grassland, and where this has not been ploughed since, the pattern has often been preserved. Surviving ridge and furrow may have a height difference of 18 to 24 in (0.4572 to 0.6096 m) in places, and gives a strongly rippled effect to the landscape. When in active use, the height difference was even more, over 6 feet (1.8 m) in places.

), the team and plough together were many yards long, and this led to a particular effect in ridge and furrow fields. When reaching the end of the furrow, the leading oxen met the end first, and were turned left along the headland, while the plough continued as long as possible in the furrow (the strongest oxen were yoke
Yoke
A yoke is a wooden beam, normally used between a pair of oxen or other animals to enable them to pull together on a load when working in pairs, as oxen usually do; some yokes are fitted to individual animals.

d at the back, and could pull the plough on their own for this short distance). By the time the plough eventually reached the end, the oxen were lined up facing leftwards along the headland. Each pair was then turned around to walk rightwards along the headland, crossing the end of the strip, and they then started down the opposite furrow. By the time the plough reached the beginning of the furrow, the oxen were already lined up ready to pull it forwards.

The result of this was to twist the end of each furrow slightly to the left, making these earlier ridge and furrows into a slight reverse-S shape. This shape survives in some places as curved field boundaries, even where the ridge and furrow pattern itself has vanished.

If the oxen had been turned right at the end of the furrow, they would immediately have had to turn right again down the returning furrow, making the line of oxen cut across the top of the ploughed strip and thus pulling the plough out of the ground before it reached the end of the furrow. Alternatively, if lined up rightwards along the headland, some would already be past the beginning of the new furrow, and these would have to be moved awkwardly sideways into the furrow to be ready to plough. Turning to the left made one turn at a time and avoided a sideways move.

As oxen became bigger and ploughs more efficient, smaller teams were needed. These took less room on the headland, and straight ploughing became easier – and easier still when heavy horses
