• One gram of healthy soil can contain up to 1 Billion microorganisms and several meters of fungal hyphae. [1]
  • The world grows 95% of its food in the uppermost layer of soil, making topsoil one of the most important components of our food system. [2]
  • For each 1-percent increase in soil organic matter, the available water holding capacity in the soil increased by 3.7 percent. [3]
  • The world’s largest known organism is a fungus (Armillaria ostoyae) that occupies 965 hectares of soil in Oregon’s Blue Mountains. That would encompass 1,665 football fields or nearly 10 square kilometers of turf.
  • There are more than 1,000 different earthworm species that aerate the world’s soils, but they can all be placed into one of the following three groups: Litter dwellers live in crop or forest litter, Topsoil dwellers live in the upper 2 to 3 inches of the soil, Subsoil dwellers live in permanent vertical burrows that can be 5 or 6 feet deep.
  • Bio-slurry and compost are excellent sources of valuable nutrients that can help to counter effects of soil acidification
  • Bio-digesters take two to three days to kill 90% of pathogens in animal manure, including E. coli and Salmonella.

  •  Fertilisers account for 50% of global food production consumed by both animals and humans. When applied at the optimum rate, 1kg of nitrogen will result in an extra 22kg of grain for most cereal crops.
  • The use of fertiliser can safeguard natural habitats and forests from being converted into farmland.- Fertilisers feed plants for better, healthier, stronger yields thatwill feed the world for centuries to come.
  • Over the next 50 years farmers will need to produce more food than has been grown over the past 10,000 years, fertilisers will play a large role in ensuring this.
  • In 1960, one hectare of land fed two people. However, by 2025, one hectare of land will need to feed five people.
