"This [imported] sugar is below the cost of production globally," SA Sugar Association chairman Bongani Linda yesterday told Minister of Rural Development and Land Reform Gugile Nkwinti. Earlier this year, the industry said it was in crisis as imports, particularly from Brazil, displaced its product and forced it to export its surplus at a poor price. "This year imports, especially from Brazil, are close to 400000t. It is about 17% of the demand and is equal to the production of three [South African sugar] mills. World changing technology enables crops to take nitrogen from the air. A major new technology has been developed by The University of Nottingham, which enables all of the world's crops to take nitrogen from the air rather than expensive and environmentally damaging fertilisers.

World changing technology enables crops to take nitrogen from the air

Nitrogen fixation, the process by which nitrogen is converted to ammonia, is vital for plants to survive and grow. However, only a very small number of plants, most notably legumes (such as peas, beans and lentils) have the ability to fix nitrogen from the atmosphere with the help of nitrogen fixing bacteria.

Not too long ago, popular wisdom ran that molecular biologists were going to save billions of people from starvation by genetically engineering crops resistant to flood, freeze, and drought; crops that could blossom from desiccated soil and bloom in salty sand; crops that could flourish despite an atmosphere saturated with carbon dioxide and rays of sunshine riddled with radiation.

Open field system. Generic map of a medieval manor, showing strip farming, from William R. Shepherd, Historical Atlas, 1923 The open-field system was the prevalent agricultural system in much of Europe during the Middle Ages and lasted into the 20th century in parts of western Europe, Russia, and Iran.[1] Under the open-field system, each manor or village had two or three large fields, usually several hundred acres each, which were divided into many narrow strips of land.
