By statistical analysis of study results it has been established that there are not any significant differences between indices of ammonifiers in brown forest soils sprayed and non-sprayed by tested biopesticides. The study indicates that BT-based insecticides, introduced into forest biocenosis, are preserved in brown forest soils during four (BT E-3, BT CM-25) or five (BT AP-8, BT AM-22) months, do not influence adversely on soil-inhabiting ammonifiers of mentioned soils and, therefore, can be widely used in plant protection.
