Question 1

Which irrigation method typically achieves the highest water use efficiency for row crops and orchards?

Accepted Answer

Drip or trickle irrigation

Answer

Drip irrigation delivers water directly to the root zone with minimal evaporation and runoff, achieving efficiencies of 85–95% compared to 50–70% for flood methods.

Question 2

When appraising irrigated farmland, which factor most significantly influences the contributory value of an irrigation system to the overall property?

Accepted Answer

The crop yields and income achievable because of the system

Answer

The contributory value of an irrigation system is best measured by the additional income or yield it enables; systems that support high-value crops with reliable yields command the greatest contributory value.

Question 3

A center pivot irrigation system irrigates land in what geometric pattern, and why does this matter for rural appraisal?

Accepted Answer

Circular — it leaves corner areas unirrigated, reducing effective acreage

Answer

Center pivots rotate around a fixed point and irrigate a circular area, leaving corner sections of square parcels unirrigated, which appraisers must account for when calculating productive acreage.

Question 4

Which factor is most critical when evaluating the adequacy of an irrigation well for rural appraisal purposes?

Accepted Answer

The well's pumping capacity (gallons per minute) and water quality test results

Answer

Pumping capacity determines whether the well can meet crop water demand, and water quality (salinity, minerals) determines suitability for irrigation; both directly affect the property's productivity and value.

Question 5

How does membership in an irrigation district or canal company typically affect rural property value?

Accepted Answer

It generally increases value by providing a reliable, legally protected water supply

Answer

Membership in an irrigation district provides access to a reliable, government-backed water supply, which supports crop production and increases the property's marketability and income potential.
