Did you apply different rates to the two fields?
No, we applied the same rates, but the results differed. In one field, we noticed an increase in yield, while in the other, we merely saved some seeds.
Generally, the subject is complex. Numerous factors affect the yield.
Plus, at that time, we were unaware of the necessity of using control lines, a feature now available in OneSoil Yield.
Despite this being our first experiment, we were pleased with the results. The positive outcomes encouraged us to further explore precision farming.
We are primarily a business, and variable-rate technology is proving to be a very effective tool for both savings and yield gains when applied correctly.
So, you conducted an experiment on two fields, liked the results, and then decided to expand the experiment?
Yes, by 2022 we had already decided to sow more sunflowers using variable-rate technology — approximately 4,000 hectares.
However, as we were still utilizing Cropwise to create our task maps, we were unaware that the zones weren’t accurately mapped. We only discovered this when we started using OneSoil Yield.
We were designing task maps based on the current vegetation — we chose NDVI images from a specific date. Ultimately, we ended up with very patchy fields with no clear zones.
Why did you decide to try OneSoil Yield?
In 2022, we sowed sunflowers without control lines.
Again, it wasn’t possible to accurately assess the results.
During that period, we had a conversation with Matvey, the manager at OneSoil. We got introduced to the OneSoil Yield functionality. I was particularly impressed by the productivity maps that OneSoil offers.
We even conducted an analysis: for the same fields, we generated productivity maps in both Cropwise and OneSoil. Along with agronomists and directors, we discussed each field individually. Indeed, they confirmed that the productivity maps with OneSoil Yield were much more precise. About half of these were spring wheat. Sunflower was the second most common crop, with spring barley also being included.
We sowed the winter crop of 2023 through OneSoil Yield, as it should be, with control lines. We then initiated the spring sowing as well — we prepared task maps for 12,000 hectares.
