Finally some Rain

The course got some much needed rain with 3/4 of an inch falling in the afternoon hours yesterday. The humidity is still very high and the chance for more showers are forecasted each afternoon for the next few days. Drought stress will be eased but disease pressure will increase until the humidity breaks. I have written earlier this year about the tissue and water testing that we are doing on a frequent basis this season and how our irrigation water is high in sodium. We have sensors in the greens that monitor temperature, moisture, and sodium. These sensors yesterday captured the rain flushing the sodium left from weeks of irrigation  away from the greens surface through the soil profile. Notice how the sodium levels increase in direct relation to the rain event.
