Every lot, package or parcel of liming material sold, offered or exposed for sale or distributed within this state shall have on each bag, package or container, in a conspicuous place on the outside, or in the case of bulk lime the vendor shall present to the purchaser a legible and plainly written statement in the English language clearly and truly certifying:
Each vehicle transporting agricultural liming material not sold on a scale weight basis must have plainly marked thereon the ton weight capacity when level full, assuming a ton of agricultural liming material occupies 20 cubic feet. Such sale on other than a scale weight basis must have prior approval of the department of agriculture.
