21.4.1. Sensors Used in Soil Testing

Try these first

1. 1.

   What do moisture sensors measure?

   Hint

   Think about what plants need to grow.

2. 2.

   What does a pH sensor assess?

   Hint

   Recall the scale used for measuring acidity.

3. 3.

   What is the primary function of moisture sensors?

   • Measure soil density
   • Measure soil water content
   • Measure soil pH

   Hint

   What do plants rely on from the soil?

4. 4.

   True or False: pH sensors can indicate nutrient availability in soil.

   • True
   • False

   Hint

   Think about the relationship between soil acidity and nutrition.

5. 5.

   Design an experiment to test how different moisture levels affect plant growth. Include the types of sensors you would use.

   Hint

   Consider the relationship between water availability and plant growth.

6. 6.

   Analyze the implications of electrical conductivity on soil fertility management.

   Hint

   Think about how salinity influences nutrient availability.
