The health of soils is key not only to agricultural productivity, but to all the ecosystem services provided in terms of maintaining the quality of water, air, and food. Nutrient inputs to agricultural soils produce large benefits to human health, including the provisioning of calories and protein supporting at least half the human population, enhancing micronutrient bioavailability in food, improving crop quality, and strengthening tolerance to plant disease. With appropriate nutrient stewardship, such inputs contribute to soil health and prevent soil degradation. When mismanaged and applied inappropriately, either mineral or organic sources of nutrients can become pollutants both in soils and in water and air. The solution being embraced by industry and governments around the world is the implementation of principles of 4R Nutrient Stewardship, ensuring that the right source of nutrient is applied at the right time, in the right place and at the right rate.
土壤健康不仅对农业生产力至关重要，而且对维持水、空气和食品质量的所有生态系统服务也至关重要。向农业土壤中投入养分，对人类健康带来了巨大益处，包括提供卡路里和蛋白质，为至少一半的人口提供营养，提高食物中微量营养素的生物利用度，改善作物质量，并增强对植物病害的耐受性。通过适当的养分管理，这些投入有助于土壤健康并防止土壤退化。如果管理不当或使用不当，无论是矿物质来源还是有机来源的养分，都可能成为土壤以及水和空气中的污染物。全世界的行业和政府正在采用的解决方案是实施 4R 养分管理原则，确保以正确的时间、地点和速率施用正确来源的养分。
