Before 2010,
there were only little information about soil quality; actually the last public
report was from 1979. But in the last years, the government has the idea of put
this topic as an important agricultural problem.
Corfo gave
900 millions of pesos for improve the actual information that includes all the
soils of the country. These is public since 2010.
This report
shows that the biggest losses of soil (erosion) in Chile are in arid and
semiarid areas between Arica and Bio-Bio region. And also talks about no apparent
erosion, which is soils with vegetation where it is not possible quantify the
soil loss.
They made categories
of classification: moderate, sever and very severe. These are necessary on
technical studies of field qualification.
In particular,
in the north of Chile, the erosion is higher than 80%, however, many of this areas
haven’t human influences. But, if we go to the south (III or IV region) there
is more human influence.
So, the
target of this project is separate soils where natural erosion predominant from
anthropic erosion.
I think
that this report it could be very important. In these times, the people use the
soil without knowing how to preserve. For example we can see fruit trees
planted in the direction of the hillslope and there is not concern about the
soil loss that this cause. It is necessary show to the agronomist and foresters
how to use properly the soil and conserve for the future.
