Weekly WeatherStation Report – July 10th, 2014
Like most of the prairies since Jun 30th, we have seen net drying and a depletion of soil reserve moisture as July does what it does best.
Below you will see a brief summary of what 1 meter depth probes picked up, plus a Leaf Disease update via captured Humidity and Leaf Wetness data. A group text was sent to customers on how to utilize these latest developments with regard to Fungicide applications.

Up to the Minute – Weather Charts
This representative graph of all 7 stations highlights the soil moisture decline as roots have now grown enough to begin pulling moisture from the 50cm probe depth and have all but drained the 10cm and soon on the 20cm.
Humidity showed its first signs of decline just last night and while this chart shows consecutively low Leaf Wetness – a major sign that leaf disease will decline rapidly without the need for fungicide – it is not accurate as sensors were not yet moved up into the canopy and scouting each of these nights and mornings anecdotally tell us that leaves were plenty wet those nights and the sensors on the ground were not capturing the big humidity effect. Sensors are being repositioned as we type.
