The “Crop Rotation Practice Standard” for the National Organic Program under the U.S. Code of Federal Regulations, section §205.205, states that Farmers are required to implement a crop rotation that maintains or builds soil organic matter, works to control pests, manages and conserves nutrients, and protects against erosion.
The Old Rotation experiment, which started in 1896, is the third-oldest ongoing field crop experiment in the United States and the oldest continuous cotton experiment in the world. It was the first experiment to show that a cotton/ legume crop rotation would allow soil to support a cotton crop indefinitely.
The Norfolk four-course system is a method of agriculture that involves crop rotation. Unlike earlier methods such as the three-field system, the Norfolk system is marked by an absence of a fallow year. Instead, four different crops are grown in each year of a four-year cycle: wheat, turnips, barley, and clover or ryegrass. [1]
Crop assignments were rotated every year, so each field segment would be planted for two out of every three years. Previously a two-field system had been in place, with half the land being left fallow. In Europe, the change to a three-field system happened from the 9th century to the 11th century. [2]
Many modern farms are made up of a number of fields, which can be cultivated separately and thus can be used in a crop rotation sequence. Crop rotation has been employed for thousands of years and has been widely found to increase yield and prevent harmful changes to the soil environment that limit productivity in the long term. [3]
Edmund Ruffin III (January 5, 1794 – June 17, 1865) was a wealthy Virginia planter, amateur soil scientist, and political activist best known as an early advocate for secession of the southern slave states from the United States.
In agriculture, monocropping is the practice of growing a single crop year after year on the same land. Maize, soybeans, and wheat are three common crops often monocropped. Monocropping is also referred to as continuous cropping, as in "continuous corn." Monocropping allows for farmers to have consistent crops throughout their entire farm.
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.
