Agralogics By Jain
Using satellite and weather data, Agralogics’ proprietary data platform can compute ETc for any field anywhere in the world – at a high temporal and spatial precision of 1/5th acre (30 meters) per day. This means that for a typical 80-acre field, Agralogics computes 400 data points per day of the field ETc.
What is crop evapotranspiration (ETc)?
Crop Evapotranspiration (or ETc) is a measure of the water that both evaporates and transpires from a field of crops during a certain time interval. It is also known as the “consumptive demand of water” or “beneficial usage of water.”
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 commonly, ETc is used as a measure to irrigate a field to replenish water used by the plant and lost from evaporation (that should be normally replaced by irrigation). Therefore, accurate and timely information of ETc helps improve the precision of quantity and timeliness of irrigation delivered throughout the season, providing dual benefits of optimizing yields and reducing water use and associated costs.
What Agralogics By Jain Will Do For You.
Annual Water Budget – segmented by month – utilizing the previous 5 years of historical satellite and weather data to compute a month-by-month average ETc enabling growers to accurately see how much total water (in acre feet) their ranches/fields are consuming. Critical data which will be required by the Sustainable Groundwater Management Act (SGMA).
Weekly ETc Report – a weekly report for each block/field for each ranch is emailed to specific Ranch Managers (for their fields) that provides a table of values of ETc for the past week – including the average ETc of the field and the ETc uniformity rank (number between 0 and 1, with 1 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.
