Suelo. Para otros usos de este término, véase Suelo (desambiguación). Se denomina suelo a la parte superficial de la corteza terrestre, biológicamente activa, que proviene de la desintegración o alteración física o química de las rocas y de los residuos de las actividades de seres vivos que se asientan sobre él. 1 .
Learn about the definition, ingredients, characteristics, and diversity of soils, the dynamic and diverse natural systems that lie at the interface between earth, air, water, and life. Explore how soils are formed, classified, mapped, and managed, and how they provide critical ecosystem services for humanity.
Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support the life of plants and soil organisms. Some scientific definitions distinguish dirt from soil by restricting the former term specifically to displaced soil.
Actualmente los dos sistemas de clasificación reconocidos en el mundo son: la Base Referencial Mundial del Recurso Suelo (WRB) y la Taxonomía de Suelos (Soil Taxonomy); ambos con sus últimas ediciones en el año 2014.
Position soils in the Global Agenda and promote sustainable soil management. The Partnership, hosted by FAO, works hard to improve soil governance to guarantee productive soils towards food security, climate change adaptation and mitigation, and sustainable development for all.
In short, soil is a mixture of minerals, dead and living organisms (organic materials), air, and water. These four ingredients react with one another in amazing ways, making soil one of our planet’s most dynamic and important natural resources. Soil is used by people in numerous ways.
