Fertilizer campaign year
Fertilizer campaign year is the July-to-June reporting year used in place of the calendar year for fertilizer statistics. IFASTAT, Statistics Canada and USDA ERS all key consumption series to it, with Statistics Canada publishing fertilizer years 2006/2007 through 2025/2026, so joining to calendar-year data misaligns periods by six months.
What is the fertilizer campaign year?
A fertilizer campaign year is the July-to-June reporting year used in place of the calendar year for fertilizer statistics. Three cataloged sources key their consumption series to it. IFASTAT notes that consumption reference periods are a mix of calendar year and fertilizer campaign year depending on country. Statistics Canada's 32-10-0039-01 table publishes fertilizer years 2006/2007 through 2025/2026 as cumulative periods within each July-June fertilizer year. USDA ERS reports consumption for the fertilizer year ending June 30.
Because the convention is country-dependent, two series that both say 2020 can describe different twelve-month windows.
Why does Fertilizer campaign year matter when choosing a dataset?
- A six-month misalignment is easy to miss. Joining July-June consumption to calendar-year crop or price data silently pairs the wrong halves of two years.
- The convention varies by country, not just by source. IFASTAT states the mix explicitly, so a global panel needs per-country period labels rather than one assumption.
- Slash labels are the tell. Statistics Canada's 2006/2007-style notation marks a fertilizer year, and a source that flattens it to a single year has already destroyed the distinction.
How do you evaluate Fertilizer campaign year in a data source?
- Read the reference-period field before joining. IFASTAT's granularity note flags the calendar-versus-campaign mix, and any source should state its own.
- Preserve the slash notation. Keep the 2006/2007-style labels from Statistics Canada's 32-10-0039-01 rather than coercing them to one year.
- Anchor to June 30. USDA ERS defines consumption for the fertilizer year ending June 30, so use that boundary when aligning other series.
- Treat the period as published metadata. The official-statistics entry covers why reference periods are part of the dataset, not an implementation detail.

Frequently asked questions
What is the fertilizer campaign year?
A July-to-June reporting year used instead of the calendar year. IFASTAT, Statistics Canada and USDA ERS all key fertilizer consumption series to it, with the exact convention varying by country.
Which sources publish fertilizer-year data?
IFASTAT mixes calendar and campaign years by country, Statistics Canada's 32-10-0039-01 covers fertilizer years 2006/2007 through 2025/2026, and USDA ERS uses the year ending June 30 for consumption.
What breaks if I ignore the campaign year?
Period alignment. Consumption keyed to July-June joined against calendar-year production or prices misaligns the two series by six months, which biases any intensity or elasticity estimate.
