• Soils are dynamic systems composed of organic, inorganic and living components.
• Soils are classified according to measurable and observable properties.
• Key physical characteristics of soils are texture, bulk density and porosity, all of which influence nutrient and water dynamics in the soil.
• Key chemical properties of soils include acidity (pH), cation exchange capacity (CEC), base saturation, organic matter content and nutrient availability.
• Soils are a slowly renewable natural resource that is being degraded worldwide due to erosion, desertification, salinization and overuse.
• Understanding, interpreting and managing soil properties can result in improved soils, more efficient nutrient utilization, improved plant performance and promotes conservation, land stewardship and sustainable practices.
Cation Exchange Capacity (CEC)
(Download)
CEC is used as a measure of fertility and nutrient retention capacity. It is expressed as milliequivalent of hydrogen per 100 g of dry soil (meq+/100g). The CEC can give insight into soil quality and site characteristics. Higher CEC likely indicates more clay, poor internal drainage, limited structure and soil compaction in high traffic areas. Low CEC is indicative of sandy textured soils prone to drought that invariably needs more organic matter to improve water holding capacity, but have open grainy structure that resist compaction.
Soil pH
(Download)
Soil pH is among the most important environmental factors which can influence soil properties and productivity, nutrient uptake and plant health and production. The pH of a soil refers to how acid or alkaline the soil is. The letters “pH” means “potential hydrogen.” The acidity-alkalinity scale ranges from 0 to 14. Soils are referred to as being acid, neutral, or alkaline, depending on their pH levels. A pH of 7 is neutral, while a pH lower than 7 is acid, and a pH higher than 7 is alkaline (basic).
