Slphychm Notes

Jim Oster

---

These notes are part of a series about soil physical chemistry (SLPHYCHM) which I will distribute during the next several years. Some notes will provide new information, and others a new perspective to existing information. I hope to write about six notes per year. The intent is to provide information and ideas along with the appropriate references. These are the references that should be cited when you use the information. Because of this, the notes themselves are purposely not numbered or dated.

I hope the information is useful to you!

• Magnesium Effects on Soil Physical Properties - Hardsetting soils and modulus of rupture.
• Magnesium Effects on Soil Physical Properties - Hydraulic Conductivity, HC
• Magnesium Effects on Soil Physical Properties - Hydraulic Conductivity and Infiltration Rate
• Potassium Impacts on Soil Physical Properties
• Exchangeable Sodium Percentage, ESP - zeolite mineral
• Reported values of exchangeable calcium for calcareous or gypsiferous soils are usually incorrect.
• Sodic Soil Reclamation By Applying Gypsum Or By Cropping?   (PDF file also available)
• CO2 Effects On Calcite Solubility and Soil Salinity
• Production functions and leaching requirements #1
• Production functions and leaching requirements #2
