How many nanometers of clay are in a sand layer?
The result is a 200-300 nanometre layer of clay around each sand particle that creates a snowflake-like formation. This increased surface area allows water and nutrients to stick to the sand and chemically combine with it rather than being lost as run off through the soil.
What happened once the soil scientists and engineers had figured out the problem?
Once the soil scientists and engineers had figured out the problem, they also had the beginnings of a solution.
Is clay good for soil?
Using clay to improve soils is nothing new – farmers have been doing so for thousands of years. However, working thick, heavy clay into soil has historically been very labour-intensive and disruptive to underground ecosystems. Ploughing, excavating and turning the soil also comes at an environmental cost as sequestered carbon is exposed to oxygen and so is lost into the atmosphere as carbon dioxide. Coupled with this is the disruption to the incredibly complex soil biome that comes with cultivation, as University of Edinburgh soil scientist Saran Sohi explains.
Can clay be used to make soil?
Clay can be a fickle beast. Too little and it has almost no impact. Too much, and the clay could form a waterproof crust on the surface of the sand or make compaction more likely. Years of trials followed, as Kristian P Olesen, a Norwegian fluid dynamics engineer, searched for a way of making a clay recipe that would easily mix with sand to turn it into life-giving soil.
Does nanoclay help sandy soils?
So while infusing clay into the sandy soils of areas such as North Africa and the Middle East, what about the rest of the world? Globally soils have lost 20-60% of their organic carbon, and nanoclay is suited to lift only sandy soils out of regression. What can you do if, for example, you have salty, non-sandy soils?
