The initial or planting fertilization is to be done on the basis of the data resulting from the soil analysis and has the purpose of heightening the soil's fertility. It is thus prevalently organic and phosphate-potassium fertilization, usually in the following doses:
manure 500q / ha;
phosphorous 100-200 fertilizer units / ha
potassium 100-200 fertilizer units / ha.
As there are many areas where manure is not available, it can be replaced with sewage sludge, solid urban waste or other organic material.
