摘要:
Rules that regulate the labeling of fertilizers and amendments are more designed to protect users from fraud than from environmental problems. Users deserve to know concentrations of all elements, essential or non‐essential, in products that they apply to their land. Labels contain warnings when boron or molybdenum are high enough to give toxicities; but with or without warning, concentrations of other elements above certain limits should also be posted. Even posting 0.0000 percent or less if applicable would be helpful. Availability data should also be given. Elemental concentrations should also be posted for amendments which sometimes could be given on the volume basis when necessary. Nutrient and non‐nutrient concentrations or ranges need to be known for amendments not classified as fertilizers. Fertilizer laws need to be adjusted to make this possible. Organic amendments should have a posted concentration or range of concentrations for organic carbon.
