Welcome to c/soilscience @ slrpunk.net!
A science based community to discuss and learn all things related to soils.
Notice Board
This is a work in progress, please don't mind the mess.
Subdisciplines of soil science include:
- Soil Taxonomy & mapping
- Soil Fertility & Organic Amendments
- Soil Chemistry & Remediation
- Soil Mineralogy
- Soil Physics
- Soil Biology
These subdisciplines are used by various other disciplines, particularly those related to reclamation, remediation, and agriculture.
Rules
- Don't throw mud. Be kind and remember the human.
- Keep it rooted (on topic).
- Please use a tag.
- No spam.

No, just fingers. You can do it using instruments, but they are slow and expensive.
If you want 'accurate' texture, you have to take the soil, put it in a cup of water, blend it up with a milkshake machine, and then measure it with a hydrometer over 24 hrs. If you're lucky, you'll get with in 15% of the actual value for that particular sample. The thing is, though, soils vary drastically even over short distances (or depths).
This is why I drink.
