He was a professor at the University of Kharkov.

He went to the St Petersburg Gymnasium before joining St Petersburg University where he studied under V. V. Dokuchaev and A.N. Beketov. A contemporary was V. I. Vernadsky.

region. This was followed by other regions during which he collected a large number of plant specimens. In 1884 he presented his work on the origin of the Chernozem. He briefly headed the Department of Botany at Kazan University. He was also involved in the introduction of plant species, making use of Australian eucalyptus trees to drain swamps. Krasnov had already begun to examine patterns in the distribution of plants within the Russian steppe in 1888. It was when he began to explore plant introduction that he began to examine climate similarities in greater detail. In 1894 he defended his doctoral dissertation on the grassy steppe regions at Moscow University. In 1912 he left Kharkov University and founded the

Botanical Garden. Krasnov used the representation F = f1 + f2 + f3 to separate the flora of the Steppe with F being the plants now found and classifying them into f1 - the original Palearctic flora, f2 - old species that have undergone change to current conditions and f3 being new species that have come into the region. The genus '' Krasnovia'' was named after him by M.G. Popov in 1950, and a mountain in the Sakhalin mountains is named after him.
