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]
Effects of crop rotation and monoculture at the Swojec Experimental Farm, Wrocław University of Environmental and Life Sciences.In the front field, the "Norfolk" crop rotation sequence (potatoes, oats, peas, rye) is being applied; in the back field, rye has been grown for 58 years in a row.
How I Plan Out Crop Rotation. I arrange my four main raised garden beds into the four following families: brassicas (cabbage, kale, etc.), nightshades (tomatoes, peppers, eggplant), greens from ...
The three-field system is a regime of crop rotation in which a field is planted with one set of crops one year, a different set in the second year, and left fallow in the third year. A set of crops is rotated from one field to another.
Crop rotation is a tried-and-true practice that has been used not just in home vegetable gardens but in full-scale farming operations since the 17th century. It consists of moving a family of ...
His remaining years were passed at Raynham, where he interested himself in agriculture. He promoted the adoption of the Norfolk four-course system, involving the rotation of turnips, barley, clover, and wheat crops. He was an enthusiastic advocate of growing turnips as a field crop for livestock feed. [8]
By affecting the soil in different ways, crops in a rotation help to stabilise changes in the properties. Another consideration is that many agricultural pests are species-specific and so having a given species present in a field only some of the time helps to prevent populations of pests from growing. [6] The organisation of individual plants ...
The farmers in Flanders (in parts of France and current day Belgium) discovered a still more effective four-field crop rotation system, using turnips and clover (a legume) as forage crops to replace the three-year crop rotation fallow year. The four-field rotation system allowed farmers to restore soil fertility and restore some of the plant ...
