Abstract

Abstract Agromineral resources are minerals and rocks used to improve soil productivity and health. These resources can be applied: indirectly, by extracting and concentrating one or more minerals by industrial processes for the production of conventional, highly soluble fertilizers; and directly, without processing, except fine grinding, for direct soil application. Agromineral resources include sedimentary phosphates, limestones/dolostones, potash and glauconite-bearing rocks of sedimentary origin, basaltic rocks, phonolites, kamafugites, and glass-rich mafic rocks of igneous origin. Among metamorphic agromineral resources, marble and biotite schist stand out. However, agromineral resources are not equally distributed on Earth’s surface, occurring more in one area than in another, and have accumulated in various geotectonic settings related to plate tectonics, being formed in specific geological time periods in Earth’s history. Therefore, these resources occur in specific “agromineral provinces” and were formed during specific “agromineral epochs”. This paper provides a conceptual framework for agromineral resource distribution in time and space. Agrominerals have a high potential to be used as directly applied soil amendments and soil remineralizers for new and innovative farming strategies, provided the amendments are low or free of contaminants.

农矿资源的时空分布——全球地质视角
农用矿物资源是指用于改善土壤生产力和土壤健康的矿物和岩石。这些资源可以间接地加以利用,通过工业过程提取和浓缩一种或多种矿物,以生产传统的高可溶性肥料;并直接,未经加工,除细磨,直接土壤应用。农业矿产资源包括沉积磷酸盐、灰岩/白云岩、含钾和海绿石的沉积岩、玄武岩、空纹岩、卡玛辉岩和火成岩的富玻璃基性岩。在变质农矿资源中,大理岩和黑云母片岩尤为突出。然而,农矿资源在地球表面的分布并不均匀,一个地区比另一个地区多,并且在与板块构造有关的各种大地构造环境中积累,形成于地球历史上特定的地质时期。因此,这些资源出现在特定的“农矿省”,形成于特定的“农矿时代”。本文提出了农矿资源时空分布的概念框架。农用矿物具有很大的潜力,可以用作直接施用的土壤改良剂和土壤再矿化剂,用于新的和创新的农业战略,只要改良剂低或无污染物。
