title: THE IMPACT OF BIOLOGICAL PREPARATIONS ON THE EFFECTIVE SOIL FERTILITY AND MINERAL NUTRITION OF APRICOT AND CHERRY PLUM SEEDLINGS
abstract: The effect of microbial preparations (MP) use, created on the basis of nitrogen-fixing and phosphorous mobilizing bacteria as well as complex of microbial preparations (CMP) on the effective soil fertility, mineral nutrition and efficiency of cherry plum and apricot seedlings growing was studied in the fruit nursery on the southern chernozems for three years. It was established that MP’s had a positive influence on the content of mineral elements in the soil and the leaves of fruit plants while
