Agronomist
Spreadsheet UNL has.
Helpful app
Something else that would be nice is to have a common irrigation threshold for soil type and crop.
Would like to be able to delete from history. Occasionally a reading gets added to history twice or one of the numbers was entered wrong. Haven't found a way to delete duplicate or wrong entry.
It is a good app in that it helps when more than one person is scheduling irrigation there is a record to look at and history to compare to.
