What can estimated soak cycles be based on?

  1. Historical rainfall data

  2. Site conditions

  3. The type of irrigation system used

  4. The age of the landscape

The correct answer is: Site conditions

Estimated soak cycles are primarily based on site conditions because these conditions significantly influence how water infiltrates into the soil and how plants utilize that water. Factors such as soil type, soil moisture retention capacity, slope, drainage, and plant types all play a crucial role in determining how long and how often water will soak into the ground effectively. While historical rainfall data, the type of irrigation system, and the age of the landscape can provide context and supplementary information, they do not directly inform the dynamics of how water interacts with the specific site being evaluated. Therefore, understanding the site conditions is essential to accurately estimate the soak cycles necessary to achieve optimal irrigation efficiency while preventing overwatering or runoff.
