Drip Irrigation Runtime By Soil Type
Runtime guidance should change with the soil, not just the tubing. Sandy soil needs shorter, more frequent watering. Clay often needs longer runtime with soak cycles so water can move in instead of running off the surface.
The calculator keeps runtime simple on purpose. It is a planning note, not an ET-based scheduling system. But that note still needs to respect how different soils actually take in water.
| Soil type | Runtime direction | Why |
|---|---|---|
| Sandy | Shorter, more frequent | Water moves through faster and the root zone dries out sooner |
| Loam | Balanced baseline | Usually the most forgiving planning assumption |
| Clay | Longer with soak cycles | Water infiltrates more slowly, especially on slope |
Why soak cycles matter
On slope or in heavier clay, two shorter cycles are often better than one long cycle. The first cycle wets the surface; the pause gives the water time to move in; the second cycle continues watering without turning the upper surface into runoff.
That is why the calculator increases soak-cycle guidance when clay and slope stack together. It is still simplified guidance, but it is much safer than pretending one long runtime is always the answer.
