A&L Canada Laboratories Fertility Seminar Series – Week #1 – pH, CEC, Optimum nutrient levels by soil type and variable rate applications
pH, CEC and Variable rate applications; CEU eligible, $40 fee
How much do you really know about soil pH and CEC?
These two soil parameters can have a huge impact on the availability of many of your macro, secondary and micronutrients.
A&L has completed years or research to demonstrate how CEC and pH levels should be used to determine the nutrient availability within a soil profile. Hear about the different methods for testing of pH and CEC and some of their short comings.
Learn how we are often managing pH and CEC as opposed to ‘fixing’ them within our fields…CEC is really a measurement of the soils ability to hold and release nutrients, so when we try to determine the amount of nutrients to include in a variable rate application recommendation, it is imperative we first understand how available and tightly bound those nutrients are within the soil.
