Which approach best guides irrigation depth and frequency in varying Florida soils?

• A. Always water to field capacity on a fixed schedule.
• B. Rely on soil moisture and texture to guide irrigation.
• C. Water until water runs out.
• D. Water only when leaves wilt.

Answer: (B)

Guiding irrigation depth and frequency by soil moisture status and soil texture recognizes that not all soils hold or drain water the same, and plant water needs change with weather. In Florida, soils range from fast-draining sandy profiles to heavier clays that hold water longer. Knowing the texture tells you how much water the root zone can store and how quickly it will lose moisture. Checking soil moisture in the root zone keeps you from overwatering sandy soils and from underwatering heavier soils, letting you refill the root zone to an optimal level without leaching or runoff. Tools like soil moisture sensors or tensiometers help you stay in the right range and you still adjust for rainfall and plant demand. The other options miss how soil type and current moisture control water availability: a fixed schedule to reach field capacity doesn’t account for variability in soils and weather; watering until water runs out wastes water and can cause drainage beyond the roots; waiting for leaves to wilt means stressed plants before irrigation is applied.
