International Congress of Soil Science imapangidwa zaka zinayi zilizonse. Pakati pa ma congress, pafupifupi misonkhano 50 ya Makomiti, Makomiti Ang'onoang'ono, Magulu Ogwira Ntchito, ndi Makomiti Oyimilira.
Pa 17th World Congress of Soil Science (Bangkok, Thailand, mu 2002), dongosolo latsopano la sayansi la Union linavomerezedwa. Izi zikuphatikiza Magawo, Makomiti, Magulu Ogwira Ntchito, ndi Makomiti Oyimilira. M'mapangidwe atsopano, pali magawo anayi aliwonse okhala ndi ma Commission.
