What is Soil Salinity?

Soil salinity is the concentration of salt in the soil. High levels of salinity can be detrimental to plant growth as it interferes with the plant's ability to uptake water, even when the soil is wet. It is commonly measured by Electrical Conductivity (EC).

Why is testing for soil salinity important?

Testing for soil salinity is crucial for sustainable agriculture and gardening. High salinity can lead to poor germination, stunted growth, nutrient deficiencies, and in severe cases, plant death. By monitoring salinity, you can take corrective measures to ensure a healthy growing environment for your plants.

How does this calculator estimate soil salinity?

This calculator uses a common method for estimating soil salinity: the 1:5 soil-to-water ratio test. By measuring the Electrical Conductivity (EC) of a soil-water slurry, it calculates an estimated EC value for the soil paste extract (ECe), which is a standard measure of soil salinity.

What is a good EC level for soil?

The ideal EC level depends on the type of crop being grown. Generally, an ECe below 2 dS/m is considered non-saline and suitable for most plants. Levels between 2-4 dS/m are slightly saline and may affect sensitive crops, while levels above 4 dS/m can cause significant issues for many plants.
