'Low yield per acre but high yield per person' is not correct for Plantation agriculture.

Plantation agriculture is the clearing of forest or land to create an area of farming for one specific crop, which is grown on a large scale. 

The passage mentions two main factors affecting the profitability of mining operations: physical factors (such as size, grade, and mode of occurrence of deposits) and economic factors (such as demand for the mineral, technology, capital, and labor and transport costs).

The concept described involves shared ownership of resources and labor by the community. 

Cooperative farming means that each farmer will remain the owner of the land but farming is done together. It has been very successful in Denmark so there it is practised on a large scale. Thus, in Denmark co-operative farming was the most successful experiment.

Extensive Commercial Grain Cultivation is practised in the interior parts of semi-arid lands of the midlatitudes. Wheat is the principal crop, though other crops like corn, barley, oats and rye are also grown.

Co-operative farming is primarily aimed at pooling resources for efficient and profitable farming. 

The process of migration from plain areas to pastures on mountains during summers and again from mountain pastures to plain areas during winters is known as transhumance.

In mountain regions, such as Himalayas, Gujjars, Bakarwals, Gaddis and Bhotiyas migrate from plains to the mountains in summers and to the plains from the high altitude pastures in winters. Similarly, in the tundra regions, the nomadic herders move from south to north in summers and from north to south in winters

Coffee plantation in West Africa was not setup by British. The French established cocoa and coffee plantations in West Africa.

Plantation agriculture as mentioned above was introduced by the Europeans in colonies situated in the tropics. Some of the important plantation crops are tea, coffee, cocoa, rubber, cotton, oil palm, sugarcane, bananas and pineapples.

"Wheat" is "not a plantation crop" because plantation crops are usually grown for profits. Wheat is grown in the large scale of heaters worldwide. Wheat is used as a stable food and principle crop worldwide.
