SOILS – PART 2: PHYSICAL PROPERTIES OF SOIL AND SOIL WATER – Pore Size
pore size is probably one of the most important physical features of a soil. It controls water and air movement and storage. Pores come in all sizes, although clays have predominantly small pores, and sands have large pores. An ideal soil condition is one with an equal number of large and small pores. Large pores allow…

Soil Water Dynamics
gold Water dynamics in soil are governed by many factors that change vertically with depth, laterally across landforms and temporally in response to climate (Swarowsky, et al., 2011). This article focuses on soil water dynamics and introduces concepts of soil moisture storage, water flow and the soil properties that influence these processes. The learning objectives discussed…

Mineral soil definition
This is an important definition and distinction from organic soils because the availability of nutrients is much different. also, an iAVS is saturated for 28 days a year 🙂 Mineral soil means a soil that is saturated with water less than 30 days (cumulative) per year in normal years and contains less than 20 percent (by…

Soil Minerals and Plant Nutrition
gold “Water is the driving force of all nature.” – Leonardo da Vinci Water is a ubiquitous and critically important substance on Earth. Essential to all living things and the health of ecosystems (Moss 2010), water is considered a prerequisite for life on other planets (Marais et al. 2008). The availability of water even partially controls…
