Soil test trends

One soil history. Every test date on one sheet.

Fictional example history.
You can start your own history, enter results and save a file to keep.
Imported files stay on your device.

Scroll within the sheet to see more dates. Mineral labels stay in place. Methods and reporting units stay separate.

Follow one result over time

A blank result means no result in this test. Values such as <0.02, >20 and starred entries retain their source qualifiers. They are not plotted as exact measurements.

Start a separate soil history

Use a separate history after a replacement or mixing event. Record where transferred soil came from. Earlier test values are not copied into the new history.

Add or correct a test result

Enter verified results from the report. PDF import is still being developed. Leave unreported values blank and retain reporting limits.

Enter the unit printed on the report. This view does not convert ppm, pounds per acre, oxide forms or paste concentrations. Different unit labels remain separate rows. For phosphorus and nitrogen, include the reporting form, such as ppm P, ppm P2O5, ppm nitrate-N or ppm NH4. Leave an unconfirmed unit blank.

Source and interpretation

This demonstration contains three fictional dates. It shows the sheet, graph and editing controls without exposing private test histories. It does not establish cause and effect.

New histories and results stay in this browser when storage is available. Save a history file for a portable backup. Opening one replaces the current displayed histories and can be undone until the next change. A browser profile or cleared browser data is not a permanent archive.

Use Save all histories and Open saved histories to carry records between devices. The CSV exports the selected soil history with all its dates and methods. It is a single worksheet layout, not a backup for reopening here.
