Boundary Creation App: Sirrus
Oklahoma State University nutrient management specialist Brian Arnall has become an authority on agricultural smartphone apps – those independent computer software application programs you can load onto a smartphone or tablet. They access information, perform a calculation, or identify a pest right on your mobile device.
Arnall blogs about apps and other crop topics at osunpk.com/. In a recent blog, he says, “Apps are nice, because the majority are stand-alone and do not need Internet or cell connection. They can be used when you are in the middle of nowhere (which is a great deal of Oklahoma) and have no service.”
About scouting and mapping apps, he says, “The only free apps that can create boundaries are Scout (telenav.com) and Sirrus (sstsoftware.com). To date, Scout remains my favorite app for in-field scouting notes. Pictures can be tagged with altitude and longitude.
“Sirrus is by far the best boundary-creation app, with easy-to-use tools for point and pivot boundaries. I was able to add 12 fields in a matter of 20 minutes. Being able to create a grid soil-sampling scheme and to record samples is also a very nice tool.
“An additional nice scouting tool is South Dakota State’s North Plains IPM app” (sdstate.edu/sdces/store/MobileApps/), he says. “It provides a pest I.D. tool with morphological drop down. It also gives management recommendations for the identified insect.”
