Soil pH
This is the term used to describe the measure of soil's acidity or alkalinity.
What is pH?
This property of soil, measured in decisiemens per meter (dS/m), indicates its salinity level.
What is Electrical Conductivity (EC)?
The ratio used to prepare soil suspensions for pH and EC measurements.
What is 1:2?
When soil pH is measured using this solution, the reading is usually lower than when measured with distilled water.
What is CaCl₂?
High EC readings in soil typically indicate an abundance of these.
What are salts?
This equipment is essential for determining soil pH and EC accurately.
What are a pH meter and an EC meter?
Soil pH affects this important factor that determines nutrient availability for plants.
What is nutrient availability?
This is the main principle behind measuring soil EC, where electrical current flow is used to indicate ion concentration.
What is conductivity?
The time soil and water are left to equilibrate before measuring pH or EC.
What is 15 minutes?
Adding this material to acidic soil raises its pH, improving conditions for some crops.
What is lime (calcium carbonate)?
A high EC in soil may lead to this condition, negatively impacting plant growth.
What is salinity stress?
This soil characteristic determines whether liming is necessary for improving crop growth.
What is pH?
This chemical solution is often used alongside distilled water to extract H⁺ ions from soil during pH testing.
What is potassium chloride (KCl)?
To calculate soil salinity in ppm, this factor is multiplied by the EC in mmhos/cm.
What is 640?
High soil EC levels can lead to reduced uptake of this essential nutrient.
What is water?
