Dry Soil facts

While investigating facts about Dry Soil Plants and Dry Soil Won't Absorb Water, I found out little known, but curios details like:

Petrichor is the word for the earthy scent produced when rain falls on dry soil.

how to tell how dry soil is?

Petrichor is the earthy scent produced when rain falls on dry soil. The scent is from water interacting with plant oils.

What plants like dry soil?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what is the smell of rain on dry soil called. Here are 23 of the best facts about Dry Soil Amendments and Dry Soil Shrubs I managed to collect.

what is dry density of soil?

1. The Amazon Rainforest loses about 22,000 tons of the phosphorus in its soil due to floods every year. The Amazon remains so fertile because the dust of a dried up lake in the Sahara Desert traveling through the atmsophere feeds the Amazon's plants the phosphorus it lost.

2. Wastewater treatment plants in the United States generate approximately 7 million dry tons of sludge each year. Because this sludge, commonly called "biosolids," is rich in plant nutrients, it is frequently applied to soils to fertilize plants and to improve the quality of soil.

3. There is an English word for the scent that is produced during rainfall on dry soil: "Petrichor"

4. Common storkbill is also able to bury its seed (to plant itself) in the soil thanks to unusual habit of fruit to twist like a corkscrew when the weather is dry and to straighten when the weather is humid. Twisting and untwisting of the fruit carries seed deep into the ground.

5. The smell of rain is called "petrichor" and is caused by oils released by plants during dry periods then absorbed by clay and soil. Humidity then releases these oils into the air

6. Winter savory and spring savory are closely related plants that differ in several aspects. Summer savory is annual plant, while winter savory is perennial plant. Winter savory is hardier plant that can survive on the less fertile soil. It has stronger flavor than summer savory and it is often used in dried form (summer savory is often consumed fresh). Winter savory has higher medicinal value than summer savory.

7. Fruits with thick peels are a result of a nutrient imbalance of nitrogen and phosphorus. Too much nitrogen will result in a dry fruit with little pulp and a bitter thick rind. A phosphorus deficiency will cause similar results. This can be fixed by adding phosphorus to the soil.

8. Extremely dense crown is made of numerous branches characterized by dichotomous branching (each branch divides twice). Parasol-like crown keeps the root in shade, prevents fast drying of soil and protects seedling from the harsh UV rays. Many species of plants and animals live in the shade of dragon blood tree.

9. The soil in forests is moist but when the trees are cleared the soil has no protection from the sun and quickly becomes dried out.

Why is my soil so hard and dry?

You can easily fact check why is my garden soil so dry by examining the linked well-known sources.

Pineapple can be easily cultivated using the crown of the fruit. Crown should be cut and partially dried before planting in the soil.

Resurrection plant quickly absorbs moist after the rainfall and enters the phase of rapid growth. Since it cannot accumulate water in the stem and root, it dries out shortly after drying of the soil and curls into a tight ball with small amount of water stored in the center. Curled in a ball, resurrection plant appears dead, but it is actually only dormant. Metabolic activities are reduced to minimum during the period of dormancy that can last few years (until the next rain).

Indian paintbrush is parasitic plant. It uses specially designed tubes called haustoria (modified roots) for the absorption of water and nutrients from the roots of nearby, host plants. Indian paintbrush can produce food via process of photosynthesis (like other green plants), but it thrives much better and survives even on the poor and dry soil when it 'steals" water and nutrients from the roots of other plants.

Geosmin is an organic compound with a distinct earthy flavor and aroma produced by an Actinobacteria, and is responsible for the earthy taste of beets and a contributor to the strong scent (petrichor) that occurs in the air when rain falls after a dry spell of weather or when soil is disturbed.

Cuban migrants are allowed to stay in the US as long as they have a "dry foot" on US soil. If they're caught at sea (wet foot) then they are sent home. This is known as the Wet foot, dry foot policy. - source
