A bill for an act providing for programs and regulations related to agriculture, including crop production, animal health, agricultural processing, and agricultural marketing, providing for powers and duties of the department of agriculture and land stewardship, providing fees, and providing penalties.

This bill establishes standardized definitions and regulations for agricultural practices in Iowa, directly affecting farmers, fertilizer producers, and the Department of Agriculture and Land Stewardship. It clarifies terms like "agricultural land" (10+ acres used for farming), "beneficial substances," and "commercial fertilizer," while requiring specific labeling for fertilizer products. Key provisions include mandating guaranteed analysis on labels showing nutrient content (nitrogen, phosphorus, potassium) and setting procedures for verifying product claims through state lab analysis. These changes aim to standardize industry practices and enforcement across crop production, animal health, processing, and marketing.
