42.3.1. Rooting Depth

Try these first

1. 1.

   What is rooting depth?

   Hint

   Think about how roots reach into the soil.

2. 2.

   What does AW stand for?

   Hint

   It's the water between two specific soil moisture levels.

3. 3.

   What is rooting depth primarily concerned with?

   • Soil type
   • Water absorption
   • Plant growth rate

   Hint

   Think about the function of roots.

4. 4.

   True or False: RZSC stands for the amount of water available between field capacity and permanent wilting point.

   • True
   • False

   Hint

   Recall the definitions of FC and PWP.

5. 5.

   A farmer has crops with a rooting depth of 0.6 m. He measures available water at 90 mm/m. Calculate RZSC and discuss its relevance.

   Hint

   Use the formula for RZSC.

6. 6.

   Explain how soil texture could affect rooting depth in crop arrangements.

   Hint

   Consider water availability in various soil types.
