在世界许多地区，粮食安全受到威胁。人均粮食产量下降的生物物理根源之一是土壤质量和数量的下降。为了扭转这一趋势，增加土壤肥力，必须补充土壤和植物养分。本文综述了在温带和热带环境中使用多营养岩石肥料提高土壤肥力的经验。讨论了施用岩石肥料的优点和局限性。提供了非洲两个成功的养分补充项目的例子，在这些项目中，当地可获得的岩石肥料被用于高度沥滤的酸性土壤。强调了在土壤肥力补充战略中结合有机材料和岩石肥料的潜力。
In many parts of the world food security is at risk. One of the biophysical root causes of falling per-capita food production is the declining quality and quantity of soils. To reverse this trend and increase soil fertility soil and plant nutrients have to be replenished. This review provides a literature survey of experiences of using multi-nutrient rock fertilizers for soil fertility enhancement from temperate and tropical environments. Advantages and limitations of the application of rock fertilizers are discussed. Examples are provided from two successful nutrient replenishment projects in Africa where locally available rock fertilizers are used on highly leached acid soils. The potential of combining organic materials alongside rock fertilizers in soil fertility replenishment strategies is stressed.
