Ziyoda az 50% -i namaksang az hamin guna konho bo rohi takshon girif­ta meshavad – (masalan, dar payoni Vosei viloyati Kulob namaki oshro az namakobhoi koni Khojamumin hamin tavr ba dast meorand). Konhoi namak i  zamoni h o     z i r a (kul, khalij va lagunahoi shur), hajmu zakhiraashon nisbatan kam boshad ham, dar kurai Zamin beshtar pahn gashtaand.
