Putting R7® to Work

By Brian Rangaard, Agronomy Sales

We’ve talked about the powerful and versatile R7 Tool in previous newsletters. WinField keeps adding power and functionality to the R7 program, and we’ve been putting that to the test in trials this spring. Here’s a brief overview of what we’ve been up to.

First, we’re using R7 satellite imagery to see how the application of iron in furrow with corn improved the vegetative cover in that field above the five-year average.

Another local study is looking at whether we can cut soybean seeding rates on our better ground and still achieve good stands and top yields. We used variable-rate planting and R7 maps to identify areas of the fields to plant at a population of 125,000 seeds per acre, as opposed to the standard rate of 150,000. So far, we’ve seen excellent emergence and stand counts at 120,000—right where we wanted them to be.

Finally, we have some nitrogen trials using three different nitrogen stabilizers. We’ll be comparing the fields throughout the growing season by walking them and using R7 imagery. The R7 program is a great tool we can use to find agronomic solutions, boost crop performance and save you money without sacrificing yield.
