Bean Cam

This app will calculate plant stand (plant population) by averaging five plant count samples randomly taken within a soybean field at the VC, V1 or V2 growth stage. The app will then use your field average stand value to calculate expected percent yield at harvest with and without spring replanting.

You can use these calculated values and the economics of your own farming operation to determine if spring replanting is a viable option. For all locations inside Wisconsin, historical median frost date for the closest township is given to help with your decision.

To take the field samples you can manually count measured rows of plants, or you can use your camera to automatically count plants. There is a help screen in the app that will get you started. It is as easy as holding your phone at arm's length and shoulder height out in front of you, with the camera facing down toward the plants at your feet. There are lines on the camera preview to show where the plant rows should line up.

This app is free. Research for the Bean Cam app was conducted by agronomy specialist from the University of Wisconsin-Madison.
