Dr Clive Rahn, an Associate Fellow at 91福利 Crop Centre, recently went to the Northwest Agriculture and Forestry University of Science and Technology in Shaanxi Province, China .The trip was part of an academic exchange during the Agricultural High Technology Fair in Yangling.

As part of his visit, Dr Rahn met with members of the UK- China Sustainable Agriculture Innovation Network (SAIN), which provides a framework for the development and implementation of collaboration on sustainable agriculture between the UK and China.

Clive was also interviewed by Wu Dun of the Shaanxi Daily. In the article Dr Rahn identified some of the key issues in China’s agricultural practices:

• In the Chinese countryside, farmers mostly continue to use the traditional fertilization methods,. which lead to blind over-fertilization with very serious environmental consequences. Few farmers use modern scientific fertilization methods, that are available, which recommend fertilizer applications matched to plant demand thus reducing the amounts of waste. Blind over-fertilization not only increases the cost of production but damages soil quality, and leads to pollution.
• The expansion of the area of China’s greenhouse is fast, and increasing. There are large amounts of irrigation and all kinds of fertilizers used, which also make the problems of excessive irrigation and fertilization more serious. This leads to more nitrate leaching and groundwater pollution.
• Farmers don’t know what to do when faced with the myriad of fertilizers available from the complex fertilizer market.
• Whilst the advanced-technology of ‘Agricultural High Technology Fair’ looks seemingly close to farmers, the ‘last step’ to the transfer knowledge farmers is very difficult.

These issues show that disseminating best practice about scientific fertilization is particularly important and urgent in China's agricultural development.

Clive was able to inform the Shaanxi Daily that the European Union has established many laws and regulations, such as the Nitrate Directive and Water Framework Directive. Each country within Europe has refined its laws and regulations to suit local conditions. The times when chemical fertilizer can be applied are strictly regulated and protected by law in Nitrate Vulnerable Zones and English farmers have a national Crop Fertilizer Recommendation Handbook.

Although the Chinese government has started to promote the measuring of soil nitrogen and other schemes for better fertilization, Clive emphasized the need for improved knowledge transfer from researchers to farmers.

Between 10th and 14th December, Rosemary Collier and Charlotte Allender visited Embrapa - the Brazilian agricultural research organisation to meet research scientists and discuss opportunities to work together in the future.

They were based at Embrapa Hortaliças near Brasilia and but also visited Embrapa Cerrados , Embrapa Cenargen (Embrapa Genetic Resources and Biotechnology) and the International Office.

Scientists have discovered 100 million-year-old regions in the DNA of several plant species which could hold secrets about how specific genes are turned ‘on’ or ‘off’.

The findings, which are hoped will accelerate the pace of research into crop science and food security, are detailed by 91福利 researchers in the journal The Plant Cell.
