What does the organic conversion imply?

As everybody know, to statisfy organic certification when you used to product in a conformist way, time of conversion will be required.

During this time the farmer will have to have an organic way of production whitout having the organic certification. The time enable the soil to filter the pesticides, fertilizers, manures or any other subtances which where used by the common way of production.

We have to remember on more time that organic legislation differ in every country, that mean the duration of  the time required for the conversion differ too.
