Crop Water Requirement and Irrigation Scheduling Across Multiple Locations

Estimates reference evapotranspiration, crop evapotranspiration, effective rainfall, crop water requirements, root-zone water balance, and irrigation schedules across multiple locations. The calculations use temperature-based procedures described in Food and Agriculture Organization Irrigation and Drainage Paper No. 56 and a workflow inspired by the 'CROPWAT' software for monthly-to-daily interpolation, aggregation into 10-day periods, and irrigation scheduling. Further details of the evapotranspiration calculations are provided by Allen, R.G., Pereira, L.S., Raes, D. and Smith, M. (1998, ISBN:92-5-104219-5) "Crop Evapotranspiration: Guidelines for Computing Crop Water Requirements" < https://www.fao.org/4/X0490E/X0490E00.htm>. The package is an independent implementation and is not affiliated with or endorsed by the Food and Agriculture Organization of the United Nations.

cropwatMUL

cropwatMUL is an R package for multilocation crop-water requirement and irrigation scheduling using temperature-based FAO-56 procedures and a CROPWAT-inspired workflow.

Development installation

install.packages("remotes")
remotes::install_local("path/to/cropwatMUL")

Basic use

library(cropwatMUL)
input <- system.file("extdata", "cropwat_example.xlsx", package = "cropwatMUL")
validate_cropwat_input(input, crop_name = "Potato")
result <- run_cropwat_one_crop_multilocation(input, crop_name = "Potato")
result$summaries
