After Flarvest. How do the memory effects shown by the other crops compare with those of winter wheat Winter wheat did not show a memory effect after one year, but oilseed rape does seem to do so. Researchers of the Agricultural Development and Advisory Service found that nitrate production by microbes in the soil after a rape crop increased with the amount of fertilizer given to the crop (R. Sylvester-Bradley, personal communication). One reason may lie in this crop s habit of shedding its leaves as harvest approaches, which means that the microbes in the soil get early access to these residues. This habit might contribute to the apparently smaller efficiency of this crop in using nitrogen fertilizer. The crop may be just as efficient as winter wheat at taking up the fertilizer but drops... 

Regular soil analysis is also important for checking the levels of the important nutrients - phosphorus, potassium, calcium and magnesium. Care should be taken to confirm the method of analysis, because the Scottish system and that carried out by organic laboratories and by Agricultural Development and Advisory Service (ADAS) laboratories have different standards. For instance, on the Scottish system, very low for potassium (the lowest level) is less than 40, whereas the...

There has been for many years a very healthy, open debate on ethics and safety questions related to experiments involving recombinant DNA. Since its creation in 1974, the National Institutes of Health Recombinant DNA Advisory Committee (NIH-RAC) has been the primary forum for this debate. Guidelines for recombinant DNA research developed by the NIH-RAC became binding on all Federally supported research and in practice have guided all research in the United States. In the USDA, an Agricultural Recombinant DNA Research Committee (ARRC) has been in place for many years in close association with the NIH-RAC and has assisted the NIH-RAC in its handling of agriculturally related proposals. 

I serve on a congressionally created committee that advises the Secretaries of Energy and Agriculture on biomass R D efforts. In 2002, the Biomass R D Technical Advisory Committee delivered its first annual report, which acknowledged, "Expanding the use of biomass for non-food and feed purposes will benefit farmers and rural areas only indirectly and modestly. A more significant development would occur if farmers themselves were able to produce the biofuels or bioproducts, either on the farm or as owners in a local production plant."6... 

Developments in the legislative framework concerning the safety of humans and the protection of the environment have been influenced by the advice from independent advisory committees. These committees are an important feature of the present system, providing expert advice not only to the HSC and HSE but also to Ministers including those in the Departments of Environment, Trade and Industry and Agriculture. Their importance cannot be underestimated.
