With the French Revolution began the institutionalization of secularized individualism in both social life and politics; individualism and rationality found expression in parliamentary government and written constitutionalism. Obviously, the English and American revolutions of and prefigure these changes, but it was the more universalist French… A larger population created a greater demand for food and consumer goods. The discovery of new gold mines in Brazil had led to a general rise in prices throughout the West from aboutindicating a prosperous economic situation. From aboutthis trend slackened, and economic crises, provoking alarm and even revolt, became frequent.
Yields have had the seed used to plant the crop subtracted to give net yields. Average seed sown is estimated at wheat 2.
Other authors offer different estimates. One of the most important innovations of the British Agricultural revolution in 18th century Revolution was the development of the Norfolk four-course rotation, which greatly increased crop and livestock yields by improving soil fertility and reducing fallow.
Rotation can also improve soil structure and fertility by alternating deep-rooted and shallow-rooted plants.
Turnip roots, for example, can recover nutrients from deep under the soil. The Norfolk System, as it is now known, rotates crops so that different crops are planted with the result that different kinds and quantities of nutrients are taken from the soil as the plants grow.
An important feature of the Norfolk four-field system was that it used labour at times when demand was not at peak levels. Later they employed a three-year, three field crop rotation routine, with a different crop in each of two fields, e. Each field was rotated into a different crop nearly every year.
Over the following two centuries, the regular planting of legumes such as peas and beans in the fields that were previously fallow slowly restored the fertility of some croplands. Other crops that were occasionally grown were flax and members of the mustard family.
Convertible husbandry was the alternation of a field between pasture and grain. Because nitrogen builds up slowly over time in pasture, ploughing up pasture and planting grains resulted in high yields for a few years. A big disadvantage of convertible husbandry was the hard work in breaking up pastures and difficulty in establishing them.
The significance of convertible husbandry is that it introduced pasture into the rotation. The four-field rotation system allowed farmers to restore soil fertility and restore some of the plant nutrients removed with the crops.
Turnips first show up in the probate records in England as early as but were not widely used till about The turnips helped keep the weeds down and were an excellent forage crop—ruminant animals could eat their tops and roots through a large part of the summer and winters.
There was no need to let the soil lie fallow as clover would re-add nitrates nitrogen-containing salts back to the soil. The clover made excellent pasture and hay fields as well as green manure when it was ploughed under after one or two years.
The addition of clover and turnips allowed more animals to be kept through the winter, which in turn produced more milk, cheese, meat and manure, which maintained soil fertility.
This maintains a good amount of crops produced. The mix of crops also changed: Grain yields benefited from new and better seed alongside improved rotation and fertility: The Dutch and Rotherham swing wheel-less plough[ edit ] The Dutch acquired the iron-tipped, curved mouldboardadjustable depth plough from the Chinese in the early 17th century.
It had the advantage of being able to be pulled by one or two oxen compared to the six or eight needed by the heavy wheeled northern European plough. The Dutch plough was brought to Britain by Dutch contractors who were hired to drain East Anglian fens and Somerset moors.
The plough was extremely successful on wet, boggy soil, but was soon used on ordinary land.Agricultural revolution: Agricultural revolution, gradual transformation of the traditional agricultural system that began in Britain in the 18th century.
