The R.J. Cook Agronomy Farm (cookfarm) is a Long-Term Agroecosystem Research Site operated by Washington State University, located near Pullman, Washington, USA. Contains spatio-temporal (3D+T) measurements of three soil properties and a number of spatial and temporal regression covariates.
Here, only the "Profiles" dataset is used from the collection.
Date column was appended from the
500 random samples were drawn from the complete sample.
The dataset was borrowed and adapted from package GSIF which was on archived on CRAN in 2021-03.
