A reason of deteriorating the growth of pine seedlings in nurseries after application of soil fumigants is found to be a phosphorus deficiency due to delay of developing mycorrhiza in 1-year-old seedlings. Mycorrhizal inoculation and phosphatization improve the growth of trees sharply and accelerate formation of mycorrhiza in seedlings after fumigation of the soil. When fumigants, herbicides and fertilizers being applied correctly, development of mycorrhiza proceeds without delay.
