Science + Data + Technology = Better Informed Irrigation Management

According to the latest USDA Census of Agriculture data, fewer than 15 percent of growers use some form of science- or data-based method to determine when to irrigate their crops.

“Many growers have not yet adopted this best practice, because it historically required them to compile massive amounts of data and perform many complex calculations,” said Brian Magnusson, vice president of technology at Lindsay Corporation. “FieldNET Advisor™ greatly simplifies that process – delivering the constantly updated information growers need to make better-informed irrigation decisions.”

FieldNET Advisor combines more than 40 years of crop and irrigation research into FieldNET® by Lindsay’s proven technology to help growers decide when, where and how much to irrigate. 

Here’s how it works:

  • Growers enter or import the field’s crop types, hybrids and planting dates 
  • FieldNET Advisor automatically combines that crop data with the field boundaries, soil maps, field-specific weather data and the as-applied irrigation history to create an extremely high-resolution grid, continuously tracking virtually every point throughout the field 
  • For each grid point, FieldNET Advisor tracks and updates the crop canopy growth and root development – continuously monitoring the water available in the root zone and forecasting the crop’s future water needs to avoid both crop stress and over-watering events
  • FieldNET Advisor then makes irrigation recommendations on when the pivots should be started and generates variable rate irrigation plans, prescribing the optimum application amount and timing throughout the field based on the forecasted water needs for each point in the field

“FieldNET Advisor combines field-specific data from various high-quality third party sources with the growers' existing as-planted data, as well as the actual as-applied irrigation history of exactly how much irrigation has been applied, when and where throughout the field to generate highly accurate and reliable irrigation recommendations,” Magnusson said. “It takes all the hassle and guess-work out of irrigation scheduling and allows growers to irrigate with confidence.”
