Crop Evapotranspiration (or ETc) is a measure of the water that evaporates from the soil and transpires from the plants in a field of crops over a certain time period. It is also known as “consumptive water use.”
ETc observes the response of a plant (or an aggregate set of plants/trees on a field) to both the weather and the stage of growth. E.g., in a hotter, drier climate, both the evaporation and transpiration get accelerated and as the plant progresses through its phenological cycle, the ETc changes for its various growth and reproductive needs.
NDVI (Normalized Difference Vegetation Index) is an indicator of photosynthetically active biomass. It is also known as a calculation of vegetation health or crop vigor. Satellites have been observing NDVI since the 1970s.
NDVI = (NIR – Red)/(NIR + Red). It basically works by mathematically comparing the amount of red and near-infrared (NIR) light signals reflected to differentiate plants from non-plant objects and healthy plants from unhealthy plants.
The most cost-effective and efficient way to measure actual, field-specific crop ET for each field and ranch –throughout the year every week
Field water consumption (ETc) is updated and emailed every 7 days.
Ranch Managers, Crop Advisors, PCAs, and irrigators can all receive thereport emails to ensure those that need the information have it.
Precipitation is reported as well to ensure accurate calculation of theirrigation amount required to replenish plant water consumption.
Uniformity shows how evenly crops are utilizing water across the field.
Cumulative YTD ET (including last year’s YTD) is included, so you can compare where the crop’s water consumption is to last year.
Accumulation Difference statistically compares the cumulative (YTD) ET of every field from the prior year to the current image allowing for immediate identification of areas in the field that got better or worse from year-to-year as the season progresses.
HyperGrowprovides a weekly report for each block/field for each ranch and is emailed for easy use. The email provides a table of values for the past week –including the average ETc of the field (inches of water the crop consumed for the week) and the ETc uniformity rank (range from 0 to 100%, with 100% being perfectly uniform). Low ETc uniformity can be an indicator of irrigation, soil, pest, or other issues in the field. A thematically colored map showing the ETcuniformity is also provided for each block/field through an active hyperlink embedded in the weekly report.
Importantly, the weekly report also quantifies the YTD ET values for the current year and compares them to the YTD values for the same period from last year to indicate whether the field is “ahead” or “behind”.
Each HyperGrow notification includes an excel spreadsheet of numbers for the previous 2 years of data. Including your uniformity trends, your water budgets, and more. E.g., for the Water Budget, historical satellite and weather data are used to compute a month-by-month average ETc.This data allows growers to accurately see how much total water each field on the ranch consumes, which can be used to develop yearly water budgets. Growers can also use their actual crop water consumption to develop Sustainable Groundwater Management Act(SGMA) compliant plans.
The most cost-effective and efficient way to see crop vigor at the field level.
NDVI report of crop vigor updated and emailed every 4-6 days for each block/field for each ranch.
Ranch Managers, Crop Advisors, PCAs, and irrigators can all receive the report emails.
Quick assessment of potential problem areas and rapid, precise deployment solutions.
Field Uniformity and Affected Acres (# of sub-performing acres) are included.
Vigor Difference image statistically compares the vigor of every pixel from the prior image to the current image allowing for immediate identification of areas in the field that got better or worse from image-to-image (4-6 days).
HyperView is delivered to your email inbox automatically with color-coded alerts to warn you of changes to your field from the previous week and from the last month. Active hyperlinks within the email easily connect you to detailed imagery and analytics with no user names or passwords to remember.
This easy-to-read and actionable information is delivered to allow you to quickly assess your fields and focus on where there might be a vigor problem or “issue” needing attention. Perhaps a drip line needs to be flushed out. Maybe the start of a pest infestation. No matter the cause, you can be sure to catch the earliest signs of vigor degradation before it is too late.
Since satellites are continuously tracking every area of your field, any change in vigor can be accurately and precisely calculated. Instead of burdening the grower with this massive amount of data, the HyperView system carefully analyses the data for you and only alerts when the negative change is above a certain threshold (nominally 10%). Compared to drones and airplanes, satellite analytics are highly regular (requiring no human intervention to analyze). This ensures low cost and high reliability to the grower.
HyperViewallows for time savings compared to the status-quo, especially since this change is detected even before a human eye can perceive it. This ability for proactive and detailed monitoring saves time and money.
HyperView is delivered to your email inbox automatically with color-coded alerts. It monitors your fields for you, so you can focus your precious time on actionable intelligence instead of just data gathering.

Lawn and Landscape Magazine just held their 2022 Technology Conference in Scottsdale, AZ that included 2.5 days of education, pre-show workshops, and the opportunity to embrace technology and move the industry forward. In this webinar our guest is Brian Horn, Editor of Lawn and Landscape Magazine who’ll walk us through all the cool technology he saw at the conference and how we can benefit from it.
