A four-ox-team plough, circa 1330. The ploughman is using a mouldboard plough to cut through the heavy soils. A team could plough about one acre (0.4 ha) per day. The typical planting scheme in a three-field system was that barley, oats, or legumes would be planted in one field in spring, wheat or rye in the second field in the fall and the third field would be left fallow.
The organisation of individual plants in a field is also variable and typically depends on the crop being grown. Many vegetables, cereals, and fruits are grown in contiguous rows , which are wide enough to allow cultivation (or mowing, in the case of fruits) without damaging crop plants.
Prior to the development of pedology in the 19th century, agricultural soil science (or edaphology) was the only branch of soil science.The bias of early soil science toward viewing soils only in terms of their agricultural potential continues to define the soil science profession in both academic and popular settings as of 2006.

Reduced tillage [note 1] leaves between 15 and 30% crop residue cover on the soil or 500 to 1000 pounds per acre (560 to 1100 kg/ha) of small grain residue during the critical erosion period. This may involve the use of a chisel plow, field cultivators, or other implements.
