How does soil electrical conductivity affect plant growth?
Soil Electrical Conductivity: A measure of the amount of salts in soil. Soil electrical conductivity affects yields, crop suitability, plant nutrient availability and soil microorganism activity such as emission of greenhouse gases and respiration. Excess salts hinder plant growth by affecting the soil-water balance.
What affects electrical conductivity of soil?
Several important factors that affect the EC value of the soil include temperature, amount of fertilizers, salinity, moisture level, irrigation and types of soil. … Water used to irrigate the crops will affect the soil salinity and nutrients content. This, in turn, affects the soil electrical conductivity.
What does electrical conductivity in soil mean?
The electrical conductivity indicates the amount of soluble (salt) ions in soil.
Why EC is important for plants?
EC is the measure of total dissolved salts in a solution, the factor that influences a plant’s ability to absorb water. In horticultural applications, monitoring salinity helps manage the effects of soluble salts on plant growth. EC is a meaningful indicator of water quality, soil salinity and fertilizer concentration.
What precautions will you take while measuring the electrical conductivity of soil?
1. The conductivity probe must be kept clean to obtain accurate measurements. Rinse the probe with distilled or deionized water prior to storage.
What is a high soil conductivity?
Soils that have a high content of clay or organic matter have a higher CEC than those that have a low content of organic matter or are sandy. DeciSiemens per meter (dS/m). —Unit of measurement for soil electrical conductivity. Equivalent to millimhos per centimeter.
Does conductivity affect pH?
There is not a direct relationship between conductivity and pH, unless the solution is in ultrapure water, and the same species is responsible for both the increased conductivity and the pH change.
