New Tools to Improve Irrigation Management, Plant Health, and Water-Use Efficiency
Cutting-edge chemistry for optimizing soil-plant-water relations
Water management is one of the biggest challenges facing the agricultural industry, especially in regions where water supplies are limited by source or community environmental restrictions. Soil surfactants and amendments have traditionally been limited by inconvenient handling and application requirements. This webinar explores a new advance in chemistry that uses existing irrigation equipment to improve the precision of delivery while increasing water holding capacity for many soil types... MORE

Turning Up the Heat on Citrus Greening
by David A. Brown
It’s like a sauna for citrus, but this is no luxury – and neither is time – for Florida growers. An innovative new approach to the long-standing plague of citrus greening employs steam to treat trees infected with the crop-wasting bacteria... MORE
Innovate to irrigate: 19 innovations to increase food production without draining the earth
Submitted by Brittany Scalise
Whenever you bite into a piece of food, do you think about where it comes from? How did it get from the ground to your table? Who are the farmers and entrepreneurs who cultivated and sourced it? It’s strange to think that this doesn’t cross our minds more often... MORE
10th International Sap Flow Conference 2017
Dynamax was proud to be a Gold Sponsor at this year’s International Sap Flow Conference held at the Arboretum in Fullerton, California. This is the first time the sap flow conference was held in the United States. The conference is sponsored by the International Society for Horticultural Science (ISHS).
Conference attendees came from around the world and consisted mostly of researchers who focus on plant water use, sap flow, irrigation, plant transpiration, and the underlying biology and physics of sap flow. Numerous applications of sap flow sensors and systems were discussed, and examples of sap flow sensor use in orchards, landscaping, agricultural crops, and forest plantations were presented.
A Wireless Sap Flow System for Irrigation Stress Monitoring on Almond
Mike van Bavel of Dynamax gave a presentation concerning the use of sap flow sensors to schedule irrigation in an almond orchard at Fresno State University. A method for extrapolating branch sap flow rates to give an average whole tree water use estimate was discussed. The whole tree water use data was compared to ET from a local weather station and a Stress Factor was produced. The presentation covered how the average tree water use and the Stress Factor were used to schedule irrigation, manage plant stress, and conserve water. The sap flow data was compared to stem water potential determined by using a pressure bomb. Results indicated that pressure bomb data was no longer required and that it correlated very well to the sap flow data.

New Logo Announcement
We are proud to announce the launch of a new company logo as part of the evolution of our company brand.
In 2013, Dynamax hit an exciting milestone with being in business for 25 years. With the success we’ve achieved in twenty five years of operation, we are looking ahead and planning for the next twenty five.
It is the perfect time to evaluate our company’s brand and logo to ensure it was in sync with who we are and where we are going. After careful consideration, we chose a new logo that represents our area of business with a more modern look. We are proud to announce the launch of the new logo as part of the ongoing evolution to our brand.
The task in the upcoming months will be to update all our brochures, manuals, business cards, etc. with our new logo. We realize that changing a logo is a process that can involve many steps and take some time, so we will finalize it gradually.
If you have used the Dynamax logo in any of your marketing materials, please assist us in updating them. If you have any questions, please don’t hesitate to contact us.

Dynamax demonstrated new Sap Flow sensors which readily monitor water consumption and water stress in almond trees
Mike van Bavel, Dynamax President, discussed the latest developments in water saving techniques with sap flow results at a test site on the FSU campus. "The plant health monitoring technique was quite comparable to having a blood pressure cuff on a persons arm at the doctor's office, for 24 hours a day", according to Mike. The sap sensor data tracked the water consumption continuously every day for 4 months in a test site, measuring stress when water was cut back, and quantified recovery after irrigation. Each day the results were transmitted wirelessly to a special web site that collected and analyzed the results. These sap flow sensors can be used on most crops and trees.
A record size audience of Almond growers and experts attended the Irrigation workshop sponsored by the Center for Irrigation Technology and PG&E Water Use Efficiency for the San Joaquin Valley Specialty Program. Since the event was overbooked, A webinar is planned for November, for those in the California central valley and elsewhere who were not able to attend.
New technology demonstrated by Dynamax showed how easily water stress and water consumed by Almond trees can be measured with new sap flow sensors.

Dynamax Opens Fresno Office
Dynamax Inc. of Houston, Texas, a provider of sap flow, soil moisture, and weather equipment for more than 25 years, has expanded by opening a new office in the Water, Energy and Technology Center on the campus of Fresno State University. It is our hope that the patented Dynamax sap flow sensors, which measure plant water use directly, can be used to help growers of California maximize their crop production while increasing water use efficiency.
Dynamax offers “real-time” plant water use monitoring for crops and trees using the SapIP system and sensors. Hourly water use and daily water use totals of sample plants are displayed and graphed on the AgriSensors webpage on the Internet. If daily water use declines over time, the amount of reduction can be used to measure drought stress, and irrigation can be applied accordingly. Plant water use, soil moisture or weather data can be collected and graphically displayed with the SapIP system. If weather data is collected, a Crop Water Stress Factor can be calculated and used to schedule irrigation.
Dynamax sap flow sensors work well on: Almond, Grape, Pear, Apple, Peach, Plum, Pistachio, Cherry, Citrus, Blackberries, Raspberries, Strawberries, Avocado, Hazelnut, Walnut, Pecan, Corn, Sunflower, Cotton, Soybeans, and many other crops.
