What our DL-TRS12 has seen since 2016

/

Since 2016, this sensor has measured soil moisture, temperature and electrical conductivity. The temperature traces ten annual cycles: into the twenties in summer, close to 0 °C in winter. The third channel, conductivity, is bulk EC — closely coupled to water content. More water means more conductive pathways, not automatically more nutrients.

Zoom in on the last few weeks. A hot, dry early summer. Then, on 19 June, a severe thunderstorm over the Zürich region — in the hours that follow, soil moisture and conductivity climb. The soil dries down again. And on the night of 1 July, heavy rain returns. In the soil it becomes an almost vertical jump. The rain falls above ground. What the DL-TRS12 shows is how much of it reaches the soil.
