This is an original vintage tri-fold advertising brochure for ‘Na-Churs’ (Nature’s) Liquid Fertilizer, produced by the Na-Churs Plant Food Co. based in Marion, Ohio. This informative piece of agricultural history details ‘5 Ways’ to grow better truck crops, including seed treatment, foliage feeding, and transplanting techniques. It features charming mid-century graphics and illustrations of farming equipment and produce. The brochure mentions the product has been ‘Tested and Proven Since 1946’ and includes references to research from Michigan State College. A great piece of mid-century Americana for collectors of agricultural or Ohio-based advertising.
