Solid wood material is built up of two major organic polymers (macro molecules) (1) polysaccharides and (2) polyphenylpropane [61,62], The polysaccharides consist of two groups - cellulose and hemicellulose, and make up around 65-75 % of the wood on dry basis. The polyphenylpropanes are more commonly termed lignins and constitute around 18-35 % of the wood on dry basis. In Table 9 we can see that wood fuels consist of extractives, minerals, and nitrogen as well. The chemical composition of wood of Sweden s most commonly wood species [63], the spruce, the pine and the birch are different, see Table 9.

The fact that the average ratio of Miner. C/Miner. N (2.83) is considerably smaller than the ratio of Org. C/Org. N of plankton (5.7) indicates clearly that the organic nitrogen in plankton is more easily mineralized than the organic carbon by microbiological activities and also that the mineralization processes are active in the lake water. This fact may account for the relationship between the ratios of Org. C/Org. N of plankton, of detritus and of surface bottom sediments, which has been shown previously.

Dissolved organic nitrogen also shows some reduction in mineral soil solution relative to the organic soil horizon. Although few data are currently available for mineral soil solution DON concentration and flux, DON reduction in mineral soil is comparable to that of DOC (Fig. 5).

The effects of five phenolic compounds, catechol, protocatechuic, p-coumaric, p-hydroxybenzoic, ferulic acids and their mixture were studied on pH, organic matter, organic-nitrogen, total phenolic content and certain inorganic ions of forest mineral soils (Ae and B horizons). The A- and B-horizon soils, were amended with 104 M concentration of each phenolic compound and their mixture. In general, soil properties were affected by phenolics amendement. However, soils amended with catechol did not influence any of the soil characteristics. Contents of organic matter, nitrogen and phosphate were lower in soils amended with different phenolic compounds compared to the unamended control soil (Inderjit and Mallik, 1997). 

Kjeldahl nitrogen is the sum of nitrogenous organic compounds, free ammonia, and ammonium. In the presence of H2S04, K2S04, and selenium catalyzer organic nitrogen is converted to ammonium. Free ammonia is also converted to ammonium. After the addition of a base, the ammonia is distilled from an alkaline medium and absorbed in boric acid. The ammonia may be determined colorimetrically at 655 nm or by titration with a standard mineral acid...
