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 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]
The drought resulted in a mass exodus of population from the prairies, as well as new agricultural practices such as soil conservation, and crop rotation. [87] The use of soil conservation practices such as crop rotation, cover crops, and windbreaks was expanded following the drought experiences of the dirty thirties. Literally layers and ...
In 1923 Canada supplied 53.3% of British grain imports and was the world's largest wheat exporter. Britain was still the country's major wheat export market well into the 1960s. The prairies became one of the world's most monocultural landscapes, wheat being 80% or 90% of all the crop in many areas.
The Government of Canada's Dominion Lands Act of 1872 served a similar function for establishing homesteads on the prairies in Canada. [23] The first years of the 20th century were prosperous for all American farmers. The years 1910–1914 became a statistical benchmark, called "parity", that organized farm groups wanted the government to use ...
The legume crop needed summer rain to succeed, and so the three-field system was less successful around the Mediterranean. Oats for horse food could also be planted in the spring, which, combined with the adoption of horse collars and horseshoes , led to the replacement of oxen by horses for many farming tasks, with an associated increase in ...
The Dutch four-field rotation system was popularised by the British agriculturist Charles Townshend in the 18th century. The system (wheat, turnips, barley and clover) opened up a fodder crop and grazing crop allowing livestock to be bred year-round. The use of clover was especially important as the legume roots replenished soil nitrates. [169]
