About World Soil Day- 5th December
World Soil Day - 5th December
The International Union of Soil Sciences (IUSS), in 2002, made a resolution proposing the 5th of December as World Soil Day to celebrate the importance of soil as a critical component of the natural system and as a vital contributor to human wellbeing.
A/RES/68/232 on World Soil Day and International Year of Soils
Under the leadership of the Kingdom of Thailand and within the framework of the "Global Soil Partnership", FAO has supported the formal establishment of the World Soil Day as a global awareness raising platform. The FAO Conference, in June 2013, unanimously endorsed World Soil Day and requested official adoption at the 68th UN General Assembly. In December 2013, the 68th UN General Assembly declared 5th of December as the World Soil Day.
Since 2012, the FAO-GSP has been organizing celebration events of this important day.

WHY SOIL IS IMPORTANT FOR ALL IN THE WORLD?
SOIL FACTS
Soil is the network of interacting living organisms within the earth's surface layer which support life above ground.
The nutritional value of the food we eat is directly related to the health of the soil in which it grows (or what it eat grows).
Management of agricultural soils should consider the structural, biological and mineral health of the soil (not just N, P, K) to produce nutritionally-dense food.
Soil has varying amounts of organic matter (living and dead organisms), minerals, and nutrients.
An average soil sample is 45% minerals, 25%, 25% air, and 5% organic matter (less in degraded soils).
Carbon is a master variable within the soil that controls many processes, such as development of soil structure, water storage and nutrient cycling.
On average, Australia’s current soil organic carbon content is only around 1%. In the 1800s, some of the most productive farms in south eastern Australia recorded soil organic carbon content of nearly 20%.
Soil high in organic carbon content enables better rainfall infiltration & retention – providing greater resilience to drought.
Every gram of soil organic carbon can hold up to 8 grams of water.
Soils are vulnerable to carbon loss through degradation, but regenerative land management practices can build soil and restore soil health.
Soil erosion within conventional agricultural practices can occur at rates up to 100 times greater than the rate of natural soil formation.
Natural processes can take more than 500 years to form 2 centimetres of topsoil.
Soil carbon takes three distinct forms: living carbon, labile carbon and fixed carbon.
- Living carbon takes the form of microbes, fungi, plant roots, nematodes, earth worms etc.
- Labile carbon in the soil comprises decomposing (dead) plant and animal material that is in a state of transition.
- Fixed carbon in the soil consists of stable compounds as humates and glomalins.
...Sequestered Carbon comprises the fixed carbon plus the total living biomass.
Soil stores 10% of the world's carbon dioxide emissions.
Around 95% of our food is directly or indirectly produced on our soils.
Microbial activity controls and manipulates the chemistry of the soil: not the other way around.
Soil microbes have a symbiotic relationship with plants - plants provide sugars to microbes and microbes make nutrients bio-available for plants.
Living organisms in soil ultimately control water infiltration, mineral density and nutrient cycling.
Fungi and bacteria help break down organic matter in the soil and earthworms digest organic matter, recycle nutrients, and make the surface soil richer.
In a handful of fertile soil, there are more individual organisms than the total number of human beings that have ever existed.
Soil is one of the most complicated biological materials on our planet.

2016 World Soil Day
2016 Theme: “Soils and pulses, a symbiosis for life”
The positive contributions of pulses to soil properties are many: they fix the atmosphere nitrogen and improve its biodiversity, fertility and structure.
Owing to their nutritional benefits, 2016 was declared the International Year of Pulses.
Soil is an essential resource and a vital part of the natural environment from which most of the global food is produced.
Soil provides living space for humans. Soil also provides essential ecosystem services, which are important for water regulation and supply, climate regulation, biodiversity conservation, carbon sequestration and cultural services.
But approximately 33% of our global soils are degraded. Policy makers and people have to explore opportunities to embrace sustainable development via the sustainable development goals.
