Research to improve cover crop growth modeling recently earned a 2025 Outstanding Paper Award from the American societies for crop, soil and agronomy. Read more about it at https://t.co/Xx17Ad9dVA @AginArk @bumperscollege @uarkhort @UARK_SoilTest @MilaPessotto @dossantoscaiol

Working with yield monitor data can be quite challenging. In this blog post, I show how pacu ( 🐟 ) can help us with this task!

The package covers three main areas of precision agriculture: yield monitor, satellite, and weather data.

I am happy to share that our newest paper is published! We developed an R package to provide support for precision agriculture applications.

Sugarcane area shows an interesting expansion from within and around São Paulo.

I was preparing a lecture on Brazilian agriculture for this week and I came up with these maps to show agricultural area dynamics over time in Brazil. I thought others might find it useful as well. Check out the Soybean area over time (1990 to 2022):

The Maize area shows interesting trends as well.

I had the opportunity to present my research at the 2023 ASA-CSSA-SSSA meeting this week. We discussed how we can use nonlinear statistical models and remote sensing to estimate crop planting and harvest dates.

For most cover crop species, cardinal temperatures are not well defined in the literature, leading to inaccurate growing degree days. The objective of this study was to determine the cardinal temperatures of 8 common cover crop species: https://t.co/xzwCnLGtHc

My first master’s paper is out!
We’ve determined the cardinal temperatures for 8 cover crop species. Thanks to all collaborators!

Our new paper showed that four decades of maize breeding has indirectly affected the rate at which maize produces new leaves. Other phenological traits were affected too. Give it a read to find out more:

Thanks to all the co-authors!

Great collaborative study, thank you all!!

@Taqwa_Tunisia I used R and the terra and sf packages.

[Caio dos Santos @dossantoscaiol]

I made these for a class that I am teaching this week and I thought they might be interesting for others too. They show where some of the main crops are produced in Brazil. The units are fraction of the municipality taken by the crop). Check out the soybean area:

There is also the distribution of Coffee:

There is also the distribution of Sugarcane:

@pascccual Photoperiod in Argentina:

[Caio dos Santos @dossantoscaiol]

As I was planning a class on the interaction between photoperiod and soybean development, I came up with this map and I thought others might find it useful as well:

[Caio dos Santos @dossantoscaiol]

@pappu817 The photoperiod calculations followed this paper. https://t.co/CLwjacenrA.
Then raster and terra packages for geospatial processing. ggplot2 for the map (365 maps, actually). magick for the GIF.

[Caio dos Santos @dossantoscaiol]

@leoNitrogen @vcgarnica A big part of the work was trying to understand the equations that represented development.

SoyStage has a new face now. Some of the features have been updated to be more user-friendly. Check it out: https://t.co/bKQqozgzkR
