Abstract/Contents: | "Nitrogen (N) mineralization in soil treated with no fertilizer (U), conventional fertilizer (C), organic + conventional fertilizer (OC), and organomineral fertilizer (OM) was studied. The net N mineralization rate and mineralization half time for the different treatments were determined. The final values suggest that the mineralization was found to be more extensive at 25°C than at 15°C, independently of the treatment fertilizer effected. Similar comments could be made for the losses of gaseous N. Also the final gaseous N losses were higher slightly with the conventional (C) and organomineral (OM) fertilizers that in the soil treated with no fertilizer (U) and organic + conventional fertilizer (OC). The treatment with organic + conventional fertilizer (OC) exhibited the greatest residual effect. The statistical treatment of changes in the inorganic N content during the incubation period showed the organic + conventional fertilizer (OC) to contain two types of N fraction with a mineralization half time of 1 day (conventional fraction) and 243 days (organic fraction, respectively). On the other hand, the organomineral fertilizer (OM) was found to contain a single N fraction the mineralization half time of which was 3 days. On the other hand, the cumulative C-CO2 evolution was significantly greater for organic matter-amended than for non-organic matter-amended soils. Also, the temperature was markedly influential in the evolution of C-CO2, highlighting the biggest values to 25°C and for the treatment OC, independently of the used temperature, due mainly to the presence of labile organic N presents in the treatment OC. The manufacturing process of the organomineral fertilizer (in a reactor at a high temperature) may favor of the more resistant N fractions, which are initially integrated in the organic fraction." |
