Final answer:
The statement is false as the ECe does not stay steady throughout the irrigation cycle; it reaches a steady state only after the system has been allowed to charge over time, and is influenced by several factors.
Step-by-step explanation:
The statement that ECe stays steady throughout the irrigation cycle is false. During an irrigation cycle, the characteristics of the system can change over time, especially when saturation levels are reached, analogous to when a capacitor in an electric circuit or a membrane in a water circuit is fully charged. In such a state, also known as the steady state, current flow (either electrical or water) ceases as long as the conditions remain unchanged. However, this state is typically reached only after the system has been allowed to charge over time; it is not constant throughout the entire irrigation cycle. Factors like soil composition, plant uptake, and evaporation can influence the balance, thereby affecting the system's capacity to maintain steady conditions.
