PFIweeds2020

The goal of PFIweeds2020 is to grant easy access to data and analysis functions for the 2020 Practical Farmers of Iowa project looking at the effect of cover-cropping on the weed seedbank.

Overview

We sampled soil from three long-term (10+ years) sites with experiments using a winter rye cover crop in a corn/soybean rotation compared to the same rotation without a winter cover crop. We took that soil back to a greenhouse, germinated the seeds, then counted/identified the weeds as we plucked them from their cozy homes and threw them on the ground. The results will be available in a publication coming soon...

Installation

The development version from GitHub can be accessed with:

# install.packages("devtools")
devtools::install_github("vanichols/PFIweeds2020")

Example

library(PFIweeds2020)

Look at the list of weeds we found

head(pfi_weedsplist)

You really want to see the raw data?

head(pfi_ghobsraw)

You can use a custom function to quickly summarise it: Total number of weeds in each experimental unit:

head(pfi_ghobsraw %>% pfifun_sum_byeu())

There is more! Probably more than you want...
