✍️ Sample CCA Questions & Answers
1. Which instrument is commonly used in the field to measure soil water matric potential and assist in irrigation scheduling?
Tensiometers measure the matric potential (tension) with which water is held in the soil, providing a direct indicator of how hard plant roots must work to extract water and when irrigation is needed.
2. What is the primary benefit of conservation tillage in soil management?
Conservation tillage helps reduce soil erosion by maintaining crop residue on the soil surface, which protects the soil from wind and water erosion.
3. Which factor is most important when choosing crops for correctional institution farming?
Climate compatibility ensures the crop can thrive in the local conditions, reducing failure and resource waste.
4. Why is soil testing essential before planting crops?
Soil testing reveals pH and nutrient levels, guiding proper fertilization and improving plant health outcomes.
5. When interpreting a soil test report, what does the 'Buffer pH' value primarily help determine?
The buffer pH test is performed when the initial soil pH is acidic (typically below 6.0). [24] It measures the soil's resistance to a change in pH, which is also known as its buffering capacity. This value is used by soil testing labs to provide a precise recommendation for the amount of agricultural lime needed to neutralize the soil's acidity and raise the pH to the target level for the intended crop. [24]
6. The Supplemental Coverage Option (SCO) in federal crop insurance is designed to:
SCO is an area-based endorsement that covers a portion of the deductible band of an individual policy, triggered when county-level losses exceed a threshold.
