I Love The Smell of Geosmin In The Morning
This is the first day of March where the temperature reached 50 degrees fahrenheit. It would be the warmest day of the year if it weren’t for that brief and freakish warm spell back in January.
We also got some rain yesterday, which is good because the containers planted with bulbs were drying out.
The moisture and mildness in the air have lent a new credibility to assertions that spring has arrived. The softness in the soil also promises good things.
Which leads me to an interesting post I just saw on the blog Soils Matter. It’s about geosmin, the organic compound that gives fresh soil its distinctive smell – which is particularly noticeable in spring. Geosmin is released by bacteria in the soil called actinomycetes.
Have you noticed that we also get that fresh soil smell when it rains? The rainwater temporarily displaces the air in the soil. When that happens, the air floats upward, carrying geosmin with it.
Anyhow, I thought this was interesting. If you want to know more, check out the Soil Matters blog.
