Bangladesh to dramatically expand technology that doubles efficiency of urea fertilizer use

19.12.2007
Urea deep placement cuts nitrogen losses significantly

The Government of Bangladesh has announced that it will expand urea deep placement (UDP)—a technology that doubles the efficiency of urea fertilizer use—to almost 1 million hectares (ha) of rice land, reaching about 1.6 million farm families, in the coming boro or dry season.

UDP is the insertion of large urea briquettes into the rice root zone after transplanting. UDP cuts nitrogen losses significantly. Farmers who use UDP can increase yields by 25% while using less than 50% as much urea as before.

The effectiveness of UDP technology in Bangladesh was proven through research funded by the International Fund for Agricultural Development (IFAD) and implemented with the assistance of IFDC—An International Center for Soil Fertility and Agricultural Development. The Ministry of Agriculture of Bangladesh has requested that IFDC help implement the expanded project.

“Millions of rice farmers in Asia depend on urea fertilizer to meet the nitrogen needs of high-yielding rice varieties,” says Dr. Amit Roy, IFDC CEO. Most farmers, including those in Bangladesh, Vietnam, and Cambodia, broadcast urea into the floodwater.

But broadcasting is a highly inefficient application method because most of the nitrogen is lost to the air and water. Only one bag of urea in three is used by the plants.

Using UDP, Bangladesh’s dry season rice production is expected to increase by 548,000 tons, according to the Department of Agricultural Extension (DAE).

“Yields were comparatively good where urea was deep placed,” says Dr. C.S. Karim, Advisor, Bangladesh Ministry of Agriculture. “If we can save at least 20% of the urea by adopting UDP technology, we can supply a large part of the country’s demand from our own factories.”

UDP technology improves nitrogen use efficiency by keeping most of the urea nitrogen in the soil close to the rice roots and out of the floodwater, where it is more susceptible to loss as gaseous compounds or runoff.

The technology not only improves farmer income, but creates employment because of the need for the briquettes. Ten Bangladeshi manufacturers have produced and sold more than 2,000 briquette-making machines. The new UDP program will include the manufacture and establishment of some 300 briquetting machines to manufacture 2.7-gram briquettes.

UDP technology was introduced in Bangladesh in the late 1990s; by 2006 more than half a million farmers had adopted UDP. Average paddy yields had increased 20% to 25%, and income from paddy sales increased by 10%, while urea expenditures decreased 32%. Farmers who use UDP can reduce urea use by 78 to 150 kg/ha and increase paddy yields by 900 to 1,100 kg/ha. The net return to farmers of using UDP versus broadcasting urea averages $188/ha.

“I’m delighted that the Government of Bangladesh endorses the merit of this technology and has asked IFDC to be a part of the project,” Roy says.

Bangladesh’s success with UDP has become a model for other rice-growing countries, Roy says. IFDC has also introduced UDP in Cambodia, Vietnam, Nepal, Nigeria, Mali, Togo, and Malawi.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
