It is unfortunate that many farmers do not respect the permissible standards when using chemical fertilizers and pesticides. I remember well last year when I saw in the daily news that the potatoes issued by the Ministry of Agriculture (in my country) were refused to be received by an European country because analyzes showed that they were used Above the permissible percentage of chemical fertilizers.
On the mention of pesticides, we are working on physicochemical analyzes of a new organic pesticide. Maybe we can discuss it someday.
Thank you, regards
