What is a good CEC?
The cations are attached to the colloid by electrical attraction between the positive and negative charges. The five exchangeable cations are also shown in soil test results as percentages of CEC. The desirable ranges for them are: calcium 65–80% of CEC, magnesium 10–15%, potassium 1–5%, sodium 0–1% and aluminium 0%.
What can HDMI CEC do?
HDMI-CEC allows devices connected to your TV through HDMI ports to communicate back and forth with your TV. The devices can have some control over the TV, and the TV can have some control over the devices. This means you could control your Blu-ray player through your TV remote, for example.

What is a good CEC number?
Organic matter has a very high CEC ranging from 250 to 400 meq/100 g (Moore 1998). Because a higher CEC usually indicates more clay and organic matter is present in the soil, high CEC soils generally have greater water holding capacity than low CEC soils.
Is high CEC bad?
Larger CEC values indicate that a soil has a greater capacity to hold cations. When a high CEC soil has good test levels, it offers a large nutrient reserve. However, when it is poor, it can take a large amount of fertilizer or lime to correct that soil test.
What are the factors that influence CEC?
Factors Affecting Cation Exchange Capacity
- Soil texture: The negatively charged clay colloids attracts positively charged cations and holds them.
- Clay soils with high CEC can retain large amounts of cations and reduce the loss of cations by leaching.
- Soil organic matter: High organic matter content increases CEC.
