Custom Seasons

Define seasonal periods for Interactive Plots and Summary Results. The anchor year is a reference year: in the example below Winter for anchor year 2025 runs from November 2024 through March 2025. A period may fall within the anchor year or extend before or after it.

Edit the names and dates, then click Apply Seasons. The same relative dates apply to every year selected in the plots and summaries, not just the anchor year. Choose Seasonal Periods there and click Update Plots or Update Summary. Periods without full data coverage (especially the first winter) are marked incomplete. Applied settings last until this page is reloaded.

Plot Options

Pasture Quality Metrics

Rows: STRIP 1–4 plus ratios (S1/S2 and S3/S4). Columns: sampling events.

Biochar Material Characterization

The experiment uses pistachio-shell biochar supplied by VGrid Energy Systems. The reports below characterize material from two production lots.

These reports describe different samples analyzed in different years using different methods. Values should not be interpreted as repeated measurements of one batch or as evidence of change through time.
