and subsequently apply additional N dressings in the growing season model growth response to N in fertilizer planning models (the most common measurements are total N and reduced N) Nitrate-N analysis in plant material A. Laboratory methods Nitrate-N is usually measured either in whole plants (e.g. lettuce, cabbage) or in particular parts (e.g. potato or cereal leaves) - both involve fine-chopping and boiling (usually in copper sulphate, CuSO 4 , potassium chloride, KCl, or water).
