Today I am going to continue highlighting resources I found helpful when studying for my prelims (which I successfully passed!). The last post on this topic was about blocking trials, and I'm glad I reviewed blocking and randomization for my exam since it was helpful in answering two of the questions on my exam. The… Continue reading Two ANOVA Tutorials

GIS Internships
Just a quick post to share that there are a bunch of GIS internships on the State Cartographer's Office website right now. Currently listed positions include jobs in Wisconsin, Illinois, Minnesota, and Missouri, and the handful I clicked on were all paid internships (>$15/hour). You can find information here: https://www.sco.wisc.edu/jobs/internships/
SAGA Resources
Here's a secret from bloggers: we get a tally of how many times each page or post gets clicked on our sites. This year I've gotten a lot of readers clicking on my older SAGA articles, so it seems like a good time to share some of my favorite SAGA resources even though it's not… Continue reading SAGA Resources
Lab Methods for Soil Testing
I occasionally write for another blog on my advisor's website and thought some readers here may be interested in a recent post-- Lab Methods for Soil Testing. I broke down some common methods for measuring soil test phosphorous and potassium. These methods can be important when you're comparing your soil test values to the critical… Continue reading Lab Methods for Soil Testing
Blocking Field Trials and the First Law of Geography
I'm studying for my prelims this semester, which involves going back over the classes I've taken over the last 4 years, reviewing my research proposal, and just generally refreshing my memory about the topics a person with a PhD in agronomy should know. I'm focusing on traditional statistics and experimental designs this week, which reminded… Continue reading Blocking Field Trials and the First Law of Geography
Degrees-Minutes-Seconds, Decimal Degrees, and Eastings and Northings
I've worked on two different multi-state fertilizer trials this year. Typically for these types of projects, collaborators from many different labs agree to all apply the same treatments, take the same measurements, and submit data to a single person to analyze and publish. I get the weirdly satisfying (and occasionally frustrating) job of formatting the… Continue reading Degrees-Minutes-Seconds, Decimal Degrees, and Eastings and Northings
Paper Size in QGIS 3 Print Layouts
I make most of my maps for publications and presentations in QGIS using the Print Layout feature. This is a wonderfully detailed tutorial if you want to learn more about print layouts. Right now I'm using the print layout to make maps of pH, organic matter, and soil test potassium to include in an update… Continue reading Paper Size in QGIS 3 Print Layouts
Global Yield Gap Atlas
I've used the Global Yield Gap Atlas for a few projects over the last couple years, and it's a great resource. GYGA measures the yield gap (difference between potential yield and achieved yield) of many crops grown in many environments, and provides downloadable data for other researchers. One tool I use from GYGA is their… Continue reading Global Yield Gap Atlas
Getting back to blogging!
Hi all! I am so sorry I took an unannounced hiatus from blogging, but I'm back and ready to share my plans for the next year of Spatially Challenged. But first, some life updates! Since I wrote to you last, I've gotten married, published two articles in Agronomy Journal, become an aunt, run my personal… Continue reading Getting back to blogging!
Choosing Chart Types
Have you ever wanted an infographic about making infographics? I found this one when looking for a succinct summary of some cool new visualization types like bubble charts and word clouds and thought it was worth sharing. Infographic from Venngage available here: https://s3.amazonaws.com/thumbnails.venngage.com/template/30a6a1a8-ecae-4479-9a46-5fe23ea0d448.png The above infographic focuses on the goals of your graphic.
