Kasvien kasvulle tärkeiden ravinteiden ja hivenaineiden pitoisuuksia maaperässä on seurattu rutiinilla jo vuosikymmeniä. Raportoidut havainnot satokasvien hivenainepitoisuuksien vähenemisestä ovat herättäneet kysymyksiä maan viljavuudesta ja ruoan laadusta.

Tässä tutkimuksessa tarkasteltiin suomalaisten viljelysmaiden hivenainepitoisuuksia vuosien 1974 ja 2018 välillä, sekä kauran ja ohran jyvien hivenainepitoisuuksia vuosien 1988 ja 2018 välillä. Maaperä- ja jyvänäytteissä ei havaittu suuria hivenainepuutoksia. Vaikka hivenainepitoisuudet ovat koko maan mittakaavassa tyydyttävällä tai hyvällä tasolla, voi puutoksia esiintyä paikallisesti.
