Question

Did you know? Sahara dust blows across the Atlantic each year and fertilises the Amazon rainforest. About 27 million tonnes of phosphorus-rich dust per year — from the ancient Bodélé Depression in Chad — provides the Amazon with 22,000 tonnes of phosphorus, exactly what rain washes away.

Accepted Answer

Sahara dust blows across the Atlantic each year and fertilises the Amazon rainforest. About 27 million tonnes of phosphorus-rich dust per year — from the ancient Bodélé Depression in Chad — provides the Amazon with 22,000 tonnes of phosphorus, exactly what rain washes away.

Stof uit de Sahara waait elk jaar over de Atlantische Oceaan en bemest het Amazoneregenwoud. Ongeveer 27 miljoen ton fosfor-rijke stof per jaar — uit het oude Bodélé-bed in Tsjaad — voorziet het Amazonegebied van 22.000 ton fosfor, precies wat regen wegspoelt.
