Mineralització de la fracció organiconitrogenada dels adobs orgànics : possibles vies per a la seva estimació
Abstract
The difficulty of forecastinf the behaviour of N-organic rich wastes as nitrogenous fertilizers are presented. Models describing the mineralization process of these materials are reviewed. Limitations of the classic Henin-Dupuis model, which introduces the isohumic coefficient k2 as a method for describing the behaviour of residual organic matter in the soil, are established. The difficulty for obtaining valid k2 values through mass balances are discussed and the characterisation of this parameter by the chemical method of the decomposition and its corollary, non-hydrolysed nitrogen are proposed. The practical significance of these parameters are briefly described and their accuracy is discussed with various examples. Finally, a possible way of considering the time of the year in the estimate of organic waste nitrogen efficiency are proposed
