Fine-tuning fertilizers to boost crop yields: Lowering fertilizer pH can increase solubility, availability of zinc

Worldwide, many agricultural soils are deficient in the nutrient zinc—despite the fact that farmers use fertilizers enriched with the element. This limits crop yields and reduces food quality. It's estimated that roughly a third of the global population consume foods low in zinc, which can increase sickness and death in early childhood, as well as impaired growth and cognition.
