Abstract


The effect of fire on the soil and the diversity of the soil is the fruit of research between two institutions: National School of Agronomy and Forestry (ENSAF) and the National Institute of Research in Exact and Natural Sciences (IRSEN). Three experimental plots have been identified to observe the response of dormant seeds to soil and their evolution after fire. In the laboratory, a portion of thirty-nine (39) cores taken from the three plots was monitored. In total 3140 seedlings were counted in plot one. In the plot two 1414 seedlings and the plot 3, this number is 3142 seedlings. The (39) cores taken from the three plots in the laboratory, there were 821 seedlings, the second plot 417 while the third plot 292 seedlings. It can be seen that the number of seedlings depends on the sampling plot and the level of the soil. After the passage of a fire, the seed bank in the soil can be reconstituted.

Keywords: Granulates, evolution, seedling, a number, banks.
