Researchers are mapping the world's manure to gain insights into nutrient cycling, greenhouse gas emissions, and sustainable agriculture practices. Manure, an organic material derived from animal excretions, plays a crucial role in soil fertility and nutrient management, but its excessive or improper use can lead to environmental challenges. By mapping manure, researchers aim to understand its global distribution, quantity, and composition. This information can inform policy-making and decision-making related to manure management, waste reduction, and nutrient recycling.
