An agronomic method for the production of vegetables and mushrooms, includes the steps ofperforming a preventive chemical, physical and pedologic analysis of the soils intended for cultivation, in order to identify their composition, hydrologic characteristics, and verify the absence of pathogens, infesting organisms and pollutants；selecting among natural seeds and mycelia, not genetically modified, the ones most suitable for the parameters of the soil identified previously； andperforming iterated periodic checks on the vegetable, mushroom species, that grow after seeding, in order to detect biotic adversities and/or infestations thereof.The method further includes the steps of performing at least one plant protection treatment by using active ingredients selected among insecticides, herbicides, acaricides, limacides and fungicides；near the time of harvest, performing iterated periodic spot checks of the vegetables, mushrooms, in order to measure the residual concentration of active plant protection principles； andupon sampling to assess the residual concentration of active plant protection principles lower than 0.01 mg/kg, harvesting the cultivated vegetables, mushrooms.
