Sugier et al. evaluated a potassium-humate formulation in an Arnica montana field study on sandy soil in Poland.
WHAT THE STUDY FOUND
Flowering stems and inflorescences increased significantly relative to controls, with greater medicinal raw-material yield and positive soil-enzyme responses.
RESEARCH SCOPE
Product-specific field study: the tested potassium-humate formulation in Arnica montana on sandy soil in Poland. The reported flowering, yield and soil-enzyme responses relate to that crop, historical formulation and field setting.
