The theoretical preconditions for the research of the hydrophily increase of the coniferous species seedlings in their treatment by liquid chemicals are presented in the article. The way to improve the hydrophilyis determined and the formula that allows to optimize the sprayer technical parameters in he coniferous species seedling treatment by liquid chemicals in the forest mechanized nurseries.
