The 1st NATO technology discussion board was once held in Biarritz in September 1990. This Taormina convention is the second one in a chain that we want to be an extended one and that i think that it has equalled the luck of its predecessor. In establishing those conferences the NATO technological know-how Committee desired to assemble top specialists to check fields of sturdy current curiosity.

G. boggy or very stony); dung/urine patches, gateways and headlands should also be excluded. Large areas within the field that have had a different manuring/fertilizing history should be sampled separately. 5 cm for grassland and 15 cm for arable. Stones and plant debris should be discarded. Sampling should be avoided after heavy rain or in time of drought. Sampling should also be avoided for 10 Chapter 1 P, K or Mg analysis for 8 weeks after applying fertilizer, 12 weeks after manure or slurry, or 12 months for pH determination after liming.

11 Experimental Planning Silage, hay and haylage A suitable corer is needed to remove sample cores from within clamps and stacks. A motor driven corer is used in some research institutes, but is rare in other establishments. One of the first designed for research work was that of Alexander (1960). His design was just 183 cm in length, and not long enough for the depth of the average farm clamp today. We designed a threesection clamp in stainless steel to resist corrosion by the volatile fatty acids in silage (Faithfull, 1997).

It is particularly useful for demanding trace element analyses. It was first developed by Professor Tölg, the method being described by Kotz et al. (1972). Pressure vessels are expensive, but digestion times can be as little as 60 s to dissolve fish tissue in nitric acid. 25 hours RCH-COOH I NH2 amino acid in protein (NH4)2SO4 Using autoanalysis, ammonium ions are reacted with sodium phenate and sodium hypochlorite to give the indophenol blue colour by the Berthelot reaction (Berthelot, 1859).
