The influence of the phase of the growing season on the mineral composition of the narrow-leaved fireweed

In the experiments the mineral composition of narrow-leaved fireweed was studied in different phases of its growing season in the conditions of the NorthWestern region of Russia in the Vologda region. It was experimentally established that narrow-leaved fireweed is a promising forage plant in the North-Western zone of Russia. It can meet the needs of lactating cows in macro-and microelements, except sodium, zinc, copper and cobalt.
