Agricultural scientist Dr Doug Edmeades, suggests to look into the sky to help comprehend what is below in the soil.

The numbers are staggering. They estimate that there are about 200 billion stars in the milky-way galaxy, and about 100-200 billion galaxies in the cosmos.

Now look down. A teaspoon of soil contained about a million microbes; a hectare of soil – several billion. Their combined weight was roughly equal to the live-weight of animals living on the soil. They come in several forms and sizes, the bacteria and fungi make up about 75% of their mass.

“So, the next time you yard some animals think of it this way: chances are you are running about a tonne of animal liveweight per hectare. About the same weight of microbes are living in the same area of soil. Marvellous don’t you think?”
