Show hintHide hint
Think about how much water is left after heavy rain.
Question 2.
Which soil type generally has the highest field capacity?
Show hintHide hint
Remember: Clay = more water retention.
3Question 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
Show hintHide hint
Consider what remains after the soil drains.
4Question 4.
True or False: Clay soils generally have lower field capacity than sandy soils.
- True
- False
Show hintHide hint
Recall the properties of different soil types.
Question 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?
Show hintHide hint
Calculate the difference between field capacity and the required moisture.
Question 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?
Show hintHide hint
Focus on the water retention characteristics of each soil texture.
