HyperGrow

  • The most cost-effective and efficient way to measure actual, field-specific crop ET for each field and ranch –throughout the year on a weekly basis

  • Field water consumption (ETc) updated and emailed every 7 days.

  • Ranch Managers, Crop Advisors, PCAs, and irrigators can all receive the report emails to ensure those that need the information have it.

  • Precipitation is reported as well to ensure accurate calculation of the irrigation 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.

WHAT IS CROP ETc

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.

Most Common Uses & Benefits of ETc

  • Determine irrigation needed to replenish water used by the plant and lost from evaporation.
  • Improves the precision of quantity and timeliness of irrigation needed throughout the season.
  • Irrigating to actual ETc is proven to optimize yields and reduce water use and associated costs.
  • ETc uniformity maps clearly identify areas within the field where crops are under stress due to insufficient water, pest pressure or nutrient deficiencies.
  • Studies have shown a direct correlation of ETc uniformity to crop yield uniformity.

WHAT IS CROP VIGOR (NDVI)

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.

Most Common Uses & Benefits of Crop Vigor (NDVI)

  • Because it is normalized, NDVI is the best tool to compare the health of your crops over time –week-to-week, month-to-month and season-to-season to improve overall yields.
  • NDVI is known to have a strong correlation with crop yield.
  • Give clear identification of irrigation uniformity problems, pests, diseases, fungus and soil problems in the field before damage is done.
  • Identifies these areas faster to focus water, nutrients and pesticides more effectively to minimize or even avoid losses altogether in many instances.

Weekly ETcReport

HyperGrow provides 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 ETc uniformity 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”.

Additional Analytics – Uniformity Trends, Water Budget and more! 

Each Hyper Grow 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 is consuming, 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.
