What essential information must all fertilizer labels include?

Fertilizer labels are required to include specific information to ensure safety, quality, and proper usage. The essential information includes the license number, brand name, and net weight, which allows consumers to identify the product, verify its registration and compliance with regulations, and understand the quantity they are purchasing.

The license number indicates that the product has been approved for sale and meets industry standards, providing assurance of its legitimacy and safety. The brand name helps to identify the specific product and its intended use. Finally, net weight is crucial for consumers to know how much product they are getting and to calculate application rates accurately.

The other options do not represent universally required elements on fertilizer labels. While information like the origin of raw materials, manufacturer's history, and packaging date may provide useful details, they are not mandated for inclusion on all fertilizer labels. Thus, the choice that encompasses the critical details necessary for identification and regulatory compliance is the one that correctly represents the essential information required on fertilizer labels.
