41.2.2. Field Capacity

Try these first

1. 1.

   Define field capacity in your own words.

   Hint

   Think about how much water is left after heavy rain.

2. 2.

   Which soil type generally has the highest field capacity?

   Hint

   Remember: Clay = more water retention.

3. 3.

   What is field capacity?

   • A) The maximum water a soil can hold
   • B) The state with all pores filled with water
   • C) Water content immediately after rainfall

   Hint

   Consider what remains after the soil drains.

4. 4.

   True or False: Clay soils generally have lower field capacity than sandy soils.

   • True
   • False

   Hint

   Recall the properties of different soil types.

5. 5.

   A farmer measures the field capacity of their clay soil and finds it to be 30% by volume. If they plant a crop requiring 25% moisture to thrive, how much water can they afford to lose before reaching a critical level?

   Hint

   Calculate the difference between field capacity and the required moisture.

6. 6.

   In a landscape with varying soil textures, shoals of sandy areas and dense clay patches intersect. How might irrigation schedules differ for each, considering their field capacities?

   Hint

   Focus on the water retention characteristics of each soil texture.
