Helen is a pistachio farmer in California. In order to reduce water consumption while still adequately watering her pistachio trees, which of the following is the BEST option?

Question

A. drip irrigation because it showers water on the tops of plants
B. drip irrigation because it uses treated wastewater on plants
C. drip irrigation because it slowly dispenses water on plants’ roots
D. drip irrigation because it replenishes evaporated water from leaves

Answer 1

C. drip irrigation because it slowly dispenses water on plants’ roots

Drip irrigation is an efficient method of watering plants as it delivers water directly to the roots where it is needed, reducing water waste. By watering the roots directly, Helen can ensure that her pistachio trees receive the necessary water while minimizing water consumption.
