42.3.2. Root Zone Storage Capacity (RZSC)

Try these first

1. 1.

   What does RZSC stand for?

   Hint

   Look for the acronym in the section text.

2. 2.

   Define Available Water (AW).

   Hint

   Think about the difference between water retained in soil and what plants can use.

3. 3.

   What does RZSC stand for?

   • Root Zone Storage Capacity
   • Root Zone Soil Compaction
   • Root Zone Saturation Control

   Hint

   Remember the acronym from our discussions on soil water.

4. 4.

   Is the following statement true or false? RZSC is calculated as the product of Available Water and rooting depth.

   • True
   • False

   Hint

   Think about how we derived the formula.

5. 5.

   Given a soil profile with an available water of 180 mm/m and a rooting depth of 1.8 m, calculate the RZSC. Discuss how this value influences irrigation scheduling.

   Hint

   Use the formula provided to calculate RZSC.

6. 6.

   Analyze how changing soil texture from sandy to clay affects RZSC and overall water retention. Discuss the implications for plant health and irrigation.

   Hint

   Consider the properties of sandy versus clay soils in moisture retention.
