Today I learned about the importance of the humus matter as its function as a water reservoir.
The course of the graph of rain run like that, at time 0.6 and 0.7 the wave runs higher than at the end and the beginning of the year and at time 0.25 lower, because of the influence of the monthly rainfall and the modified rainfall. The waves of the graph exist, because of the influence of the weather. So the graph of the rain was composed out of the influence of the weather and the modified rainfall. The other influences don’t change the run of the graph.
