US Ag Dealers Lead the Way on Precision Agriculture
Bruce Erickson, Purdue University, and James Lowenberg-DeBoer, Harper Adams University
The 19th CropLife-Purdue Survey of precision agricultural practices by US agricultural input dealers shows that the American grain and oilseed sector continues to lead the way with commercialization of digital technology. Some highlights from the 2019 survey:
- Ninety two percent of the respondents used some type of Geographic Positioning System (GPS) guidance in providing farmers with custom fertilizer and pesticide application services. Ninety percent of respondents use autosteer and over half of dealers use both lightbars and autosteer.
- Most dealers are now using pooled farm data to make soil fertility and seed decisions. For crop nutrient decisions, 80% of dealers said phosphorus and potassium decisions were at least somewhat influenced by pooled data, up from 43% just two years ago, and 79% saying nitrogen decisions were being influenced, up from 39% in 2017.
- Dealers expect variable rate application of pesticide to increase dramatically in the next three years. For the last decade about 20% of ag dealers have been offering VRT pesticide application, but respondents expect that to jump to 50% by 2022. That dramatic increase is probably related to technical developments in machine vision and weed recognition which will allow dealers to offer target weed control services to farmers in the near future.
