Researches have shown that the efficiency of sulfonylurea herbicidesstrongly is influenced by soil acidity and the content of a humus. Use of herbicide Terrsan in sowings of the first year of a Pinus silvestrisin the dosage of 30 g/ha is possible at pH to 5.5 pH and humus content of more than 3%. At acidity 5.5–6.0 рНand the content of a humus less than 3% the application dose should not exceed 20 g/hа. In sowings of Picea abiesat the content of a humus more than 2% it is possible to use dosing 20 g/ha. At lower content of a humus an entering dose should not exceed 10 g/ha.
