Why do I like the smell of wet soil?
The human nose is extremely sensitive to geosmin and is able to detect it at concentrations as low as 5 parts per trillion. Some scientists believe that humans appreciate the rain scent because ancestors may have relied on rainy weather for survival.
What is the smell of sperm?
Semen normally smells like ammonia, bleach, or chlorine. Semen is about 1 percent sperm and 99 percent other compounds, enzymes, proteins, and minerals. Many of these substances are alkaline. This means that they’re above a 7 on the pH scale, which is measured from 0 (highly acidic) to 14 (highly alkaline).
Why does my plant smell like rotten eggs?
The most common culprit of a rotten egg smell coming from plant pots is excessive watering. The bacterium causing the odor needs an abundance of water to live and breed. This excessive moisture leads to root rot, which can prove fatal to the plant. Removing the plant from the pot can confirm this diagnose.
What is the smell of wet soil called?
Humans aren’t the only ones to appreciate the earthy aroma after an April rain shower. That smell—known as petrichor—stems from microscopic streptomycete bacteria in the soil that produce a compound called geosmin, The Times reports.

Amending the Soil Mix a 2- to 4-inch-thick layer of compost or another organic material, such as aged manure, into the top 8 inches of soil using a tiller or shovel. Repotting indoor plants in new, well-draining potting soil can help keep a soil odor from returning.
Why does fresh air smell so good?
