FREE IA Soil-Water-Plant Relationships Questions and Answers
Why is soil texture important in irrigation planning?
Correct! Wrong!
Soil texture affects water retention and infiltration, influencing how often and how much to irrigate.
What is field capacity in relation to soil moisture?
Correct! Wrong!
Field capacity is the amount of water the soil holds after excess water drains, important for irrigation scheduling.
Which factor most directly influences plant water uptake?
Correct! Wrong!
Root zone moisture availability is the key factor influencing plant water uptake for growth and survival.
What is the primary role of evapotranspiration (ET) in irrigation?
Correct! Wrong!
ET measures the total water loss from soil and plants, guiding irrigation scheduling.
How does compaction affect soil-water-plant relationships?
Correct! Wrong!
Compacted soils restrict water movement and root growth, decreasing irrigation efficiency.
What happens when water is applied faster than the soil’s infiltration rate?
Correct! Wrong!
Water applied too quickly runs off rather than infiltrating, leading to wasted water and erosion.
