Biofarm too science-fictiony ?
Bio farms are resource buildings in Tropico 4: Modern Times that take the place of farms. (Discovered 1957) They take up much more space than old farms do and employ fewer people, but they produce multiple crops at a time. No matter what work mode a bio farm is set to, it produces a supply of corn on the side.
Work Modes: 1} Corn: produces corn in all its fields. 2} Food Crops: grows bananas, papayas, and pineapples. 3} Cash Crops: coffee, tobacco, and sugar.
It seems to me that Biofarming is the European English for what is commonly known in the U.S. as Organic Farming. Of course, all farming was organic before the introduction of artificially compounded inorganic chemical fertilizers.
Biodynamic agriculture is different, although related. Wikipedia says:
The development of biodynamic agriculture began in 1924 with a series of eight lectures on agriculture given by philosopher Rudolf Steiner at Schloss Koberwitz in Silesia, Germany, (now Kobierzyce in Poland east of Wrocław). The lectures, the first known to have been given on organic agriculture, were held in response to a request by farmers who noticed degraded soil conditions and a deterioration in the health and quality of crops and livestock resulting from the use of chemical fertilizers. The one hundred and eleven attendees, less than half of whom were farmers, came from six countries, primarily Germany and Poland. The lectures were published in November 1924; the first English translation appeared in 1928 as The Agriculture Course.
Steiner emphasized that the methods he proposed should be tested experimentally. An agricultural research group, directed by Erhard Bartsch, was formed to test the effects of biodynamic methods on the life and health of soil, plants and animals; the group published a monthly journal Demeter. Bartsch was also instrumental in developing a sales organisation for biodynamic products, Demeter, which still exists today. The research group, renamed The Imperial Association for Biodynamic Agriculture in the 1930s, was dissolved by the National Socialist regime in 1941.
So when holistic, organic agriculture became important depends on your cultural focus. It was important in Germany long before it had any practical impact in the U.S.
