When posted in Latvia, he met several students including the exiled revolutionary Olga Zandrok.
After her period of exile had ended, he left the army, moved back to St. Petersburg with Olga and began to study the agricultural sciences at the Institute of Forestry.
Lesgaft had been dismissed from St. Petersburg University for his political views but gave private lessons in anatomy, and Morozov attended them.
In 1896, he was sent to study forest management in Germany and Switzerland and spent time at the Eberswalde Academy with Professor Adam Friedrich Schwappach.
Morozov introduced the term "silvics" and considered the forest to be a connected and complex system, rather than a mere collection of trees.
