6. Soil-Water Relationships

Try these first

1. 1.

   What is root zone soil water?

   Hint

   Think about where roots go when plants need water.

2. 2.

   Define field capacity.

   Hint

   Consider how much water a sponge can hold after soaking.

3. 3.

   What is the maximum water a soil can hold after excess drainage?

   • Field Capacity
   • Wilting Point
   • Available Moisture

   Hint

   Think of a sponge that has soaked up as much water as it can.

4. 4.

   True or False: The wilting point indicates when plants have enough moisture.

   • True
   • False

   Hint

   Consider how you feel when you're very thirsty.

5. 5.

   A farmer has two types of soil on his land: sandy and clay. If his sandy soil has a field capacity of 25% and a wilting point of 10%, and his clay soil has a field capacity of 40% and a wilting point of 15%, how much available moisture does each type of soil provide?

   Hint

   Use the formula: Available Moisture = Field Capacity - Wilting Point.

6. 6.

   Discuss how a farmer can improve infiltration rates in compacted soil. Consider possible practices or techniques.

   Hint

   Think about how different farming practices affect soil health.
