— How does OneSoil help you be more effective?
Well, we had bad luck with barley crops... In 2019, our fields got hit by harsh frosts (which is common in the south of Brazil). The plants suffered terribly, especially in the low-lying sites.
We usually apply a growth regulator on the barley, but this time we didn't need to apply it to all crops.
I checked NDVI images in the app and identified the damaged areas. It turned out that in our 815-ha field, only 214 ha needed a growth regulator. The other 601 ha didn't need it anymore. In the OneSoil web app
, I created a prescription map for the machinery based on NDVI zones. I applied the product to the zones where healthy crops needed it and left the damaged areas untouched. By doing that, I saved about $10,000, and the total cost of the growth regulator for the whole field fell from $15/ha to $4/ha.
Moreover, if we had applied the product to the damaged plants, it would have led to a loss in productivity.
So, by using the prescription map based on the NDVI zones in OneSoil, I saved money and avoided a drop in productivity. — Sounds great! We're so happy to hear that the OneSoil app is helping you combat the whims of nature. How do you use the app when everything's going right?
I use the web app to monitor crop development and identify problem areas. If something goes wrong, I can go to that particular spot and check it out for myself.
I also monitor crop development using charts and compare the field conditions on different dates. The Growing Degree-Days chart
really helps me to monitor crop development. (To build a chart in the OneSoil web app, go to the 'Weather' tab and select the field you want to build a chart for — OneSoil)
. It especially comes in handy for us in the winter.
This month, we applied fungicides according to NDVI zones. In July, some crops got damaged by frost and we did variable-rate application. We didn't apply the product to the damaged crops because they didn't need it.
