World Soil Day 2022: Soils, where food begins
Did you know that there are more living organisms in a tablespoon of soil than people on Earth? Soil is a world made up of organisms, minerals, and organic components that provides food for humans and animals through plant growth.
Like us, soils need a balanced and varied supply of nutrients in appropriate amounts to be healthy. Agricultural systems lose nutrients with each harvest, and if soils are not managed sustainably, fertility is progressively lost, and soils will produce nutrient-deficient plants.
Soil nutrient loss is a major soil degradation process threatening nutrition. It is recognized as being among the most critical problems at a global level for food security and sustainability all around the globe.
Over the last 70 years, the level of vitamins and nutrients in food has drastically decreased, and it is estimated that 2 billion people worldwide suffer from lack of micronutrients, known as hidden hunger because it is difficult to detect.
Soil degradation induces some soils to be nutrient depleted losing their capacity to support crops, while others have such a high nutrient concentration that represent a toxic environment to plants and animals, pollutes the environment and cause climate change.
World Soil Day 2022 (#WorldSoilDay) and its campaign "Soils, where food begins" aims to raise awareness of the importance of maintaining healthy ecosystems and human well-being by addressing the growing challenges in soil management, increasing soil awareness and encouraging societies to improve soil health.
