Soil Fertility, Fertilizers, and Crop Nutrition: Past, Present, and Future

Abstract

AbstractOver the past few decades, the North American fertilizer sector has experienced significant transformations, integrating into the global supply chain, which is pivotal for sustaining an abundant source of food, fiber, and energy. While the fundamental fertilizer products containing N, P, K, and S have remained largely unchanged, common fertilizers have evolved into agricultural commodities that are extensively traded on a global scale. Consequently, farmers often lack visibility into the origins of the fertilizers used for their crops. The role of the modern plant nutrient industry is essential for feeding a hungry world and preventing degradation of vital soil resources. There is growing awareness of the need for enhanced nutrient stewardship to meet local, regional, and global concerns. This is the second article in a three‐part series on the past, present, and future of the North American fertilizer industry.
