Amp Up Tech to Predict Corn Drydown

Cornfield ready for harvest

The need to monitor drydown trends in your cornfields comes at one of the busiest times of the season. Prioritizing sample collection and stand assessment in every field is difficult when there are so many other things to do. Let tech ease the load, give you a global perspective and  optimize your ROI potential by helping you determine the appropriate harvest order for your fields.

 

Why use tech to predict corn drydown?

The lower the normalized difference vegetation index (NDVI), the lower the amount of chlorophyll in the corn plant and the less biomass in the crop as a whole. Having low-NDVI fields means these plants are drying down faster, so you can determine which ones to begin harvesting first. Tech tools can help you monitor crop vigor and moisture from your tablet so you can get an overview of all your fields and plan for an ordered and timely harvest.

 

Using technology to track your cornfields over time can reveal different rates of drying and allow you to further refine your harvest plans. For example, two fields may both be at 25% moisture on a given day, but a week later the tool may show that one field has dried much faster than the other and should be moved up in your harvest schedule.

 

Knowing how quickly corn plants are drying down, especially if your area has an exceptionally rainy harvest season, can help you forecast how much propane you’ll need. Tapping into the R7® Field Forecasting Tool for this information can help you be more efficient. Using this technology to target the fields you and your agronomist need to scout and moisture-test — rather than driving many miles to sample every single field — could save you time and money.

 

Pair tools for improved outcomes

Use the R7 Field Monitoring Tool to keep tabs on plant health. The imagery allows you to see trends in declining vigor and moisture levels. Following up with the R7 Field Forecasting Tool helps predict drydown speed and allows you to prioritize fields for harvest. Field conditions in the Upper Midwest were extremely variable this spring, ranging from ideal conditions in spots to cold temperatures and wet soils in other regions at planting. The Field Forecasting Tool also helped farmers determine which fields had higher yield potential than others so they could decide where fungicide applications would generate the highest ROI potential.

 

Verify the findings

I’ve worked with a number of farmers who used the R7 Field Monitoring Tool to find out which of their cornfields would be ready to harvest first, then used the Field Forecasting Tool to ascertain the moisture level of that grain according to the model. To see if these results were ringing true, they also scouted and used a hand moisture tester. The results matched.

 

Farmers have told me they value the benefits of tech to help them make these decisions and that they were excited to use this process and these tools to predict grain moisture drydown at harvest. The R7 Field Forecasting Tool even indicates when corn will be going into black layer and how the season will finish.

 

As the season winds down, your time becomes increasingly limited. Take advantage of technology. Mining the layers of information in crop modeling solutions can help you prioritize harvest order, target applications and get optimal ROI potential and yields of quality corn — even if you need to work remotely with your retailer to take advantage of them.
