Resting ("fallowing") a different third of the land each year in theory allowed a third more food to be grown (as two-thirds would now be cropped rather than a half) and allowed for the introduction of legumes which returned nitrogen lost by the soil when planted with cereals, though fertility still relied heavily on the availability of livestock manure (perhaps the reason why many areas retained the two-field rotation, which might be less demanding of additional soil nutrients). So (again in theory) a third more people might be fed, though this would vary according to local conditions.

A three-class voting system is a voting structure where each voter can choose among three options or candidates in an election or decision-making process. This system allows for a more nuanced expression of preferences compared to a simple binary choice.
Istanbul and Tehran both have populations of 3 more than five million people.
It is difficult to provide an exact number as Russia does not have comprehensive statistics on the racial demographics of its population. However, estimates suggest that there are around 40,000 to 70,000 people of African descent living in Russia.
The two field system has two fields use so one half was used to make barley,grain and rye. While the three field system used 2/3 of the field while the third field was layed for fallow.

Installing a 3 room mini split system in a home offers benefits such as energy efficiency, individual room temperature control, quiet operation, and improved air quality.
The reason for the 3 field system is so that 2 of the fields can grow crops and the 3rd of the fields wouldn't have anything growing but they would, put animals there to fertiliser the crops
Installing a mini split 3 zone system in a home or commercial space offers benefits such as energy efficiency, individual temperature control in different areas, and cost savings compared to traditional HVAC systems.
The three-field-system worked when the farmer has three separate fields that he wanted to use to plant different crops on. Field 1 would have wheat, Field 2 barley, and Field 3 is left fallow. Then the farmer would rotate the crops the next year, planting wheat or barley in Field 3, then Field 1 would be planted with barley or wheat respectively and Field 2 left as fallow. Next year Field 1 would be left fallow and Fields 2 and 3 are planted with barley and wheat. Ultimately this system allows each field to rest for one year out of being used for 2 years. Sometimes some farmers or producers would use that field that they are keeping fallow for some extra grazing for their cattle or their neighbor's cattle so that nutrients via manure can be incorporated back into the soil. For today's farming community, a field that is left alone for one year is a field that is making them loose money, so they have to make use of that field they are not using for cash crop production, be it for hay, or extended grazing.
