Post-harvest fertilization in super-intensive crops such as olive trees, fruit trees or almond trees, as well as grapes (table and wine grapes) is a necessary process at the end of a campaign. Once harvesting is over trees are left “exhausted”, having put all their nutritional resources into producing their fruit. It is important to bear in

agriculture In total, plants need at least 16 elements, of which the most important are carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, potassium, calcium, and magnesium. Plants obtain carbon from the atmosphere and hydrogen and oxygen from water; other nutrients are taken up from the soil. Although plants contain sodium, iodine, and cobalt, these are apparently not essential. This is also true of silicon and aluminum. Overall chemical analyses indicate that

Once a crop has been harvested, it enters a state of rest prior to the resumption of its biological cycle. Before it flowers, the plant starts to build up reserves of substances which it will use to help with the budding and flowering in the next biological cycle. That is why there is a step
