OFPEDATA

Example data from Montana State University's On-Farm Precision Experiments project. Used to demonstrate the utility of the OFPE Tools R-Package.

Installation

You can install the released version of OFPE from GitHub with:

# install.packages("devtools")
devtools::install_github("paulhegedus/OFPEDATA")

Information

This package contains example data related to the On-Farm Precision Experiments (OFPE) project at Montana State University. This data is used to demonstrate the usage of the OFPE Tools R-package in the associated vignettes of that package. It contains field and farm boundaries as well as raw data collected on farms. This data is primarily used to show users how to set up their OFPE formatted PostgreSQL database in the first step of the OFPE data workflow. See the OFPE Tools package for more information and links to further resources. OFPE Tools Github: https://github.com/paulhegedus/OFPE.git

OFPE CropScan 3300H Visualization Application

The data included in this package are from real farms. Wheat yield and protein data are included, gathered from yield monitors on crop combines, and an aftermarket CropScan 3300H grain protein content monitor installed in the cab. Yield data are collected at a much denser rate than protein (~3 seconds vs. ~10 seconds). As-applied input data such as nitrogen fertilizer and seed rates are also included. These data are collected directly from sprayer/spreader and seeder equipment.

For each field represented in this package there are at least two data files for each year data was collected on that field. These include yield and an as-applied input shapefiles, and in some cases grain protein content 'csv' CropScan files. Finally, there is a field boundary shapefile and a farm boundary within which the field falls. These are used to create the OFPE formatted database. Again see the OFPE Technical Website and the OFPE Project Website for more detailed information on the OFPE data workflow and project.

There are three fields from three different farmers included in the package. Two are conventionally managed fields where the varied input is nitrogen fertilizer, and one is an organic field where the seeding rate is varied. Both conventionally managed fields are in Montana and have had two years of experimentation (2016 and 2018) and include as-applied nitrogen fertilizer, winter wheat yield, and grain protein content. The organically managed field is in Manitoba, and contains spring wheat yield and seeding rates from 2019 and the previous crop, oats, yield from 2017.

Funding

The OFPE project was initially funded by the Montana Research and Economic Development Initiative (MREDI) and is continued to be funded by the Montana Fertilizer Advisory Committee (MFAC). Other funding sources include the Montana State University College of Agriculture (MSU CoA), the MSU Department Land Resources and Environmental Sciences (LRES), and the Montana Institute on Ecosystems (MT IoE). Other support and funding has been provided by the Data Intensive Farm Management project at the University of Illinois (DIFM). Funding for Paul Hegedus is provided by MSU and the Graduate Student Grants from the Western Sustainable Agriculture Research and Education (WSARE).
