Harvest is here!  As it gets under way, it is a good time to remember what you did throughout the season on your fields and take notes on how that might have affected your yield. One thing that might have made an effect is whether you put a residual herbicide, like Dual, in with your soybean post application.

In the pictures above & below, Dual was applied on part of field.  The grower ran out of Dual while spraying and decided to finish the field without it. This field had a preemergent of Sonic and the post was sprayed in mid-June. This shows that residuals help prevent late season weed emergence. This is something to keep in mind as we go through harvest and start planning for next year. Have a safe and happy harvest.

The year of the soybean?!?!?

Yield reports on the beans in our area have been fantastic with many field averages landing in the 60-80 bu/acre range on the early maturing varieties that have been harvested!  Corn yield estimates look to be promising as well.  With some luck we will get some heat back next week to help drop the moisture in the corn and save everyone some money on drying this fall!

In saying that, I would caution holding off too long to combine some of these corn fields – make sure to get out there and check the integrity of your stands.  Corn rootworm pressure was higher this year than it has been in recent years.  Combine that with a few strong wind events in our area this growing season and it may be worth taking some fields in the low to mid 20% moistures versus waiting for the upper teens.

This time of year is a great time to get caught up on any grid sampling that is due.  Big yields are great and that is what we strive for every year.  However, remember that bigger yields equal larger crop nutrient removal rates.  Please contact your agronomist and go thru those numbers- we must continue to plan and fertilize for big crops if we expect them every year.

Thank you to all of you who continue to take time to help with all the trials we run thru our AYS program.  Without your cooperation our data is limited and likewise, our ability to make the most solid recommendations going forward!

We all have some long hour days coming ahead, please take time to think of your well being and keep yourselves safe out there!

Harvest is underway! Locally, I would say 10% of soybeans are combined and some growers are starting on corn, which looks a little different than last year at this time. Local bean yields and corn yields  have been strong, even though we got dry in the later half of July and August. We have a weigh wagon at our Lewiston location and would be more then happy to help you understand how your crops are yielding and help you calibrate the monitor.

This is a great time to let your Ag Partners team know of any on-farm trials you have positioned such as: hybrid comparisons, fungicide, variable rate planting, seed treatment, insecticide, nitrogen etc. We can help you collect and analyze the data this fall. We all get better as a result from learning together about new solutions that could help you move the mark on production and profitability. Its awesome to see an earlier harvest then the last couple years due to earlier planting and a warmer growing season!

We hope you all have a safe and successful harvest!

Using the Yield Layer in Fertilizer Recommendations to Maintain High Yields

One strategy we can use for fertilizing is fertilizing by crop removal using the yield map layer.  In AYS we can take the current year or multiyear yield map and generate a crop removal fertilizer recommendation based off it.  In the simplest terms, we apply more fertilizer spatially on high yielding areas and less fertilizer on low yielding areas within a field.

The map below is an example of spreading by a crop removal map.  This field is highly variable with 150-bushel yield swings across the field.  By using the yield file vs flat rate recommendations, we are putting back enough fertilizer on the high yielding areas and not over applying fertilizer in low yielding areas.  These types of recommendations can be executed as a standalone or as part of a fertility build recommendation. The early crop yields in 2020 are near record breaking, and despite this, we are still seeing large spreads in yield variability.  In the fall of 2020, consider a fertilizer recommendation that uses a yield file to maintain fertility in our high yielding A zones and not over apply fertilizer in our low yield C zones.

This week has provided challenges for harvest with the wet mornings, cool days, and pop up rain showers – the soybeans are having a hard time drying out. Yields on what has been combined are all over the board ranging from 50-70+ bu/ac, depending on if it was sprayed with fungicide or not. This year fungicide is looking like it will pay back very well for growers that sprayed it.

A couple guys have harvested some corn around low to mid 20’s on moisture and pretty good yields. I think more guys will switch over and start doing corn if the beans stay wet due to weather.

We had a storm come through Wednesday afternoon with lots of pea size hail and it did not do the beans any good.  Next week’s forecast looks very promising and field progress should definitely turn around.
