Reading soils in the field, horizon by horizon.
This profile points to an orthic topsoil over a red apedal horizon, with soft plinthic development at depth, consistent with the Bainsvlei soil form.
The profile face reveals what assumption alone cannot.

📢New paper out:
"A classification framework for mapping lunar soils"
We propose a structured system to classify lunar soils for ISRU and future Moon missions — tested on the Apollo 15 deep core.

Gram Strain pt 3! Biofilms are very important for bacteria to keep themselves secure and allow them to stick to their surroundings. Bacteria otherwise would be flushed away and struggle to
contribute to soil formation :(

Fragipan (Pedology 🟤)
A fragipan is a diagnostic horizon in USDA soil taxonomy. They are altered subsurface soil layers that restrict water flow and root penetration. Fragipans are similar to a duripan in how they affect land-use limitations. In soil descriptions, they are commonly denoted by a […]
Andosol (Pedology 🟤)
Andosols are soils found in volcanic areas formed in volcanic tephra. In some cases Andosols can also be found outside active volcanic areas. Andosols cover an estimated 1–2% of Earth's ice-free land surface. Andosols are a Reference Soil Group of the World Reference Base […]
Hilo (soil) (Pedology 🟤)
Hilo soil is the official state soil of the state of Hawaii. These soils cover about 21,000 acres and are considered prime agricultural land. The Hawaiian definition of the word “Hilo” is “first night after the new moon.” Also, the word is the Polynesian term for […]

Sapric (Pedology 🟤)
A sapric is a subtype of a histosol wherein virtually all of the organic material has undergone sufficient decomposition to prevent the identification of plant parts and even fecal matter. Muck is a sapric soil that is naturally waterlogged or is artificially drained […]
Grit (supplement) (Pedology 🟤)
Grit is a material eaten by birds to aid in their diets and digestion. Wild birds find grit naturally while foraging, and farmers can purchase grit for their domestic fowl. There are two forms: soluble grit, which dissolves in a bird's digestive system and is […]
Woohoo, big new SMap update is out! smap.landcareresearch.co.nz/maps-and-too... we've all been working our butts off on this one.
If you need me, I'll be clicking around the web map and second guessing myself at every turn 🙃 #pedology #nzsoils #solmapping
Soil profile with dark(almost black) organic layer at the top, a light eluviated horizon, and the Bs horizons at the bottom in shades of dark brown and rust. Fine roots throughout.

Charlottetown (soil series) (Pedology 🟤)
Charlottetown soil series is the name given to a deep fine sandy loam soil which has developed under forest vegetation on glacial till. This series occurs only on Prince Edward Island, where it is widespread and so […]

Pedosphere (Pedology 🟤)
The pedosphere 'ground, earth' and σφαῖρα 'sphere') is the outermost layer of the Earth that is composed of soil and subject to soil formation processes. It exists at the interface of the lithosphere, atmosphere, hydrosphere and biosphere. The pedosphere is the skin of […]

Imogolite (Pedology 🟤)
Imogolite is an aluminium silicate clay mineral with the chemical formula Al2SiO34. It occurs in soils formed from volcanic ash and was first described in 1962 for an occurrence in Uemura, Kumamoto prefecture, Kyushu Region, Japan. Its […]

Plinthosol (Pedology 🟤)
Plinthosols are a reference soil group in the World Reference Base for Soil Resources, developed by the Food and Agriculture Organization. They are characterized by the presence of plinthite, petroplinthite, or pisoliths—concretions formed through pedogenic processes […]
Pedology (Pedology 🟤)
Pedology is a discipline within soil science which focuses on understanding and characterizing soil formation, evolution, and the theoretical frameworks for modeling soil bodies, often in the context of the natural environment. Pedology […]

Hwangto (Glaciology 🗻)
Hwangto, a Korean loess soil, is a yellow-coloured soil, which contains high levels of potassium chloride and calcium. Hwangto is sometimes called a 'living soil' for its medical effects. Korean loess called “Hwangto”or “the red yellow soil or earth” has been a basic […]
Paleopedological record (Paleontology 🦕)
The paleopedological record is, essentially, the fossil record of soils. The paleopedological record consists chiefly of paleosols buried by flood sediments, or preserved at geological unconformities, especially plateau escarpments or sides of river […]
Apparently my kid argued with his teacher that pink is not a color (it's not, it's just light red). He's definitely a future pedologist and is perfecting his arguing of semantics. #Soil #Pedology
