2.1 技术简介

技术定义:

In the Loba province of Burkina Faso, the production, storage, processing and marketing of organic cotton has been promoted since 2004 by Helvetas.

2.2 技术的详细说明

说明:

Organic cotton production adheres to the principles and standards of organic farming. Any application of synthetic fertilizers and pesticides and the use of genetically modified varieties are forbidden. Organic cotton relies on a combination of different measures: (1) the use of organic fertilizers (manure or compost) and recycling of organic matter; (2) Crop rotation and/or intercropping; (3) Careful selection of varieties adapted to local conditions (climate, soil, pests and diseases); (4) Biological pest management (in combination with careful monitoring of crops); (5) Clear separation of organic and conventional cropland, e.g. by growing border crops (to avoid contact with chemical substances through spray drift or surface runoff); and (6) Soil and water conservation measures. Timely crop management (e.g. weeding) is very important. In Loba rotations crops include sesame (a cash crop), cereals and legumes (food crops), while intercrops include leguminous green manure and trap plants. The best adapted cotton variety is FK-37. Bio-pesticides are produced based on neem seeds (Azadirachta indica). The measures listed above help to improve soil fertility, reduce production costs (and thus financial risk) and avoid the negative effects of conventional farming: declining yields, resistance to pests and diseases, health hazards and environmental problems caused through the use of chemicals. By relying on inputs available/produced on the farm and by getting a better price for certified organic products, profitability of the farm is improved in the long run despite of lower productivity compared to conventional or genetically modified (GM) cotton. Farms need to complete a 3-year conversion period to change their production system from conventional to organic. Farmers have to maintain records and documents for periodic inspection and certification (Internal control system).
