Prior to the introduction of the three field system, a two field system was used. With the two field system, a field was plowed for a crop every other year, and was allowed to lie fallow on the off years. With the three field system, the fields were allowed to lie fallow every third year, and the crops were changed between crop years. The two field system had 50% of the fields productive at any time, but with the three field system, this was increased to 67%. The effect was to increase the area of land under cultivation by a third.
With the increase in the amount of land under cultivation, the farms could provide work for an increased number of farmers, and a larger agricultural surplus to feed people living in towns and cities.
There were other factors that also increased agricultural surpluses, including the inventions of the horse collar and the heavy plow. And the result of all of these is that the numbers of people who could devote time and energy to work other than agriculture was more than doubled.
Prior to the use of the three field system, there was a two field system used.
Under the three field system, a field was tilled and planted with a crop one year, tilled and plated with a different crop the next year, and allowed to lie fallow in the third year.
By contrast, the two field system had a field tilled one year and fallow the next.
The fallow field had a production value that was far lower than that of a tilled field, even if animals grazed on it, and for vegetable or grain crops is not considered productive at all.
So under the three field system, two thirds of the fields were producing, where under the two field system, only half of them were. Since two thirds is 133% of one half, this represented a 33% increase in the tilled land available.
The use of horse collars, horse shoes, and the heavy plow meant that a single horse could till far more land, and this meant that the increase in the available land did not require an increase in agricultural workers. This produced an increase in the food supply. And the increase in the food supply meant more people could live in towns and cities.
The three field system contributed to the increase in populations and numbers of towns and cities.
The three field system increased agricultural production in Western Europe. This lead to a situation in which a smaller number of farmers could feed a greater number of people, and this meant some of the farmers could get jobs in towns and cities. The growth of towns and cities lead, in turn, to an increase in industry and trade.
This system allowed the multiplications of harvests.
It allowed peasants to produce more crops
It was important because that's how the lords got their money
It was important because of the natives!
The Sumerian Irrigation System was important. since they had drought, this helped get water to crops.
He outlined the system of governemnt as described in Article I. He was a part of the Constitutional Convention and signed the document.
System Maintenance is very important because you need to keep your computer and system up to date and safe. It is very important to run security and windows updates everyday so that you can reduce the chance of getting viruses and spyware. It is also important to the performance of the machine because if you don't keep your computer clean then it's not going to run as good as it should.
The Dewey Decimal System classification system is so important because it allows libraries to order the books correctly.
The lymphatic system is so important because if your lymphatic system does not work then that is where all of the bacteria comes out from. if your lymphatic system does not work then your lymph nodes will not work then that is where the bacteria is suppose to be taken out but if it is not there then you will have germs in your body that is why your lymphatic system is so important.
So you can have babies:)
So you can live!
they are important to help many other reflect
10 is so important because we use a base-10 counting system.
It is very important and it is important to keep it strong so you don't get sick as easily.
A classification system is important for various reasons. It makes it easy to identify a particular group which is classified based on specific criteria.
The Respiratory System is important to us because you can breathe or do anything without it. It is the main part of you body.
His discovery was so important because he made the solar system come to life.
It was important because that's how the lords got their money
It is SO much easier to calculate stuff with a sensible system of units!
