TEST  PLOT  DATA

Valley Ag Supply wants to be the information provider to the agricultural community in southeast South Dakota. We work hard to find data that is local and/or relevant to our area to determine what products will work best in your operation. Valley Ag Supply will put in their own test plots, but will also rely on other sources for information. Ask one of our agronomists or check out some of the information for yourself. 

Valley Ag Supply's Test Plot Data 

2018

The 2018 growing season was a difficult year for our test plots. As with a lot of fields in our area, a majority of our test plots drowned out from the unusually wet weather we experienced, which resulted in a lot of inconclusive data. 

Below is the soybean yield data from our Asgrow and Croplan varieties that we were able to obtain from a test plot near Vermillion and Big Springs.

In the future, we hope to be able to provide you with a lot more information and data from our test plots. 

As always, if you have any questions, give us a call. Whether it is trying to find specific information or want to come up with a plan of what products to use on each of your fields, we would be glad to help. We realize that their is a lot of information and data available online and it can be hard to sift through it all and understand what it is trying to tell  you. Our unofficial motto is 'agronomy leads,' which means we want to find out and do what is best for your fields and farming operation. 

Additional Test Plot Information

If you want to do some research on your own, below are a few resources that we would recommend.  

We also use Winfield United’s R7 tool which uses over 200 answer plot sites from around the country to test hybrids and management styles on multiple soil types. We use their hybrid characterization charts, insight trials, and performance mappers to help us place seed based on offensive and defensive characteristics, management styles, and soil types. An account is needed to access this website so a grower can come to our office to sit down with us and compare multiple hybrids on a variety of soil types.
