Soil Salinity

Figure from experiment 7 from Earth Science with Vernier

Introduction

Soil salinity is a measure of the saltiness of the soil. Many plants have trouble growing in soil that contains too much salt. High soil salinity makes it more difficult for plants to get water from the soil and can interfere with their obtaining the proper nutrients.

Soil salinity is determined by measuring the electrical conductivity of a soil-water mixture. The higher the salinity of the soil, the higher the conductivity of this mixture will be.

In this experiment, you will use a Conductivity Probe to measure the salinity of several soils. The unique units of soil salinity require a special note. Soil salinity is commonly reported in units of dS/m, deciSiemens per meter.

Objectives

In this experiment, you will

  • Use a Conductivity Probe to measure the salinity of soil samples.
  • Predict plant response to the salinity of the soil.

Sensors and Equipment

This experiment features the following Vernier sensors and equipment.
