On the TREC campus nestled in Homestead, the frost made for some lovely winter scenes.
On a recent data downloading expedition, the Water Resource Engineering team had an opportunity to survey field upon field of burned or severely burned crops.
We also saw the promise of hardier and bountiful tomorrows….
…and persistent efforts to save the salvageable.

What began as a practice video to help familiarize us with Extension's newly acquired Sony HD camera developed into something completely different in the editing process. In fact, the narrative demanded a much broader scope so I was able to complement the newer clips with segments dating back to our earliest works.
At the moment, we are contemplating submitting this video to the Borscht Film Festival, a local, artist-run indie celebration of Miami-inspired and Miami-focused cinema. Our perspective is unique and I think worthy.
Is it that good? You be the judge! Screen it and if you can envision it projected at the Performing Arts Center in downtown Miami (or not), comment on this post. Feedback is encouraged and appreciated!

Last month we held a program in Homestead where I gave a short presentation on this. If you would like to see it: www.watereducationalliance.org and follow the 'education' tab.
In response to this, Florida has filed a lawsuit against EPA. More information on this can be found at:

These videos were produced to supplement Miami-Dade Extension’s educational literature geared toward alarmed residents in areas of the county where the infestation has been particularly harsh (Doral, Miami Springs, etc.). Currently, the videos are prominently displayed on Miami-Dade Extension’s main webpage.
Check them out!

In an effort to get people besides Mike and me to blog - I'm going to offer a challenge! I hope that every now and then, someone can post a great memory from our group. Here is the start!
Great teamwork! These two worked really hard last summer.

Today an extension event was held in Homestead for water quality BMPs - primarily focusing on ornamental nurseries. We had some great tours and speakers. This program was organized by the Water Education Alliance for Horticulture (www.watereducationalliance.org) and Dr. Paul Fisher from UF-Gainesville. We saw some beautiful plants! And, some great BMPs! Thanks to Costa and Living Color for hosting us!

Following a study by ABE graduate student Isaya Kiseka that successfully used a ET-based controller in a star fruit orchard, the Water Resource Engineering team installed an off-site ET-based timer on a pressurized irrigation system servicing a young avocado orchard at TREC in Homestead, FL.
The set-up for the avocado orchard system includes additional instruments.
Since the off-site signal does no account for instantaneous rain events, a rain sensor was added to the controller. This sensor will suspend irrigation after it collects a specific depth of water and will sustain suspension until it dries.
A water meter was also added to the system’s mainline to track irrigation event frequency and duration.
Several tensiometers were also installed in the field to insure that irrigation is reaching row ends.
To view short videos about previous Water Resource Engineering team studies conducted in the aforementioned avocado orchard and with the aforementioned ET-based controller, follow these links:

I have been in Homestead since early September focusing exclusively on the Snapper Creek Project - learning the different devices and troubleshooting some discrepancies in the systems. The following is a short summary of this project.
Erected this summer, the weather and soil water monitoring site at Snapper Creek (Miami, FL) is collecting data for use by water managers in Miami-Dade County to develop water and energy conservation measures for urban landscape irrigation systems.
Equipment installed at the site:
1. Wind speed sensor that measures accurately wind speeds in the range of 0 to 100 mph.
2. Temperature (-40o to + 60oC) and Relative Humidity (0 to 98% RH, non-condensing) probes.
3. Two Tipping bucket rain gages with 0.01 inches (0.254 mm) per tip.
4. Three Water content reflectometers to measure soil volumetric water content.
5. Two Soil temperature probes (-35o to + 50oC).
6. Precision Infrared radiometer (Field of view, 22o half angle).
7. Two Soil heat flux sensors (±2000 Wm-2).
8. Two Solar radiation sensors to measure incoming and reflected solar radiation.
9. Net radiometer.
Two Campbell Scientific data loggers (CR800 and CR1000) are used to collect the measured data. The PC400 software is used to download data from the data loggers.
Data collection at the Snapper Creek site will continue for several years. Ideally, somewhat better understood thanks to what I was able to accomplish this past month.
