Bin tally for your crop insurance production report
Measure each bin with a tape, add what you've already delivered, and this totals your harvested production by crop and by field, in bushels and tonnes, ready to copy onto the SCIC Crop Production Declaration or the AFSC or MASC Harvested Production Report. Print it or save it as a PDF.
Have a grain settlement on paper? Send me a photo and I’ll check it against your contract, free, within a day.
Your bins stay in this browser only, until you start again. Keeping them in GrainPosition puts them on a free farm book's bin map, where you arranged them, so next fall's report starts from them.
How to measure a bin
Round bin. Measure the diameter, or the distance around the bin with a tape, whichever is easier. Then the depth of grain at the wall: from the floor up to where the grain meets the wall (the eave height less the empty space above the grain). If the grain is peaked, add the height of the peak above that line; if you unloaded from the centre and it's coned down, put the depth of the cone and tick "coned down".
Hopper bin. As a round bin, with the grain's depth measured from where the hopper meets the wall, plus the hopper's own height from its bottom to that ring. The hopper is worked out with AFSC's pile formula, as AFSC says to.
Flat storage or a rectangular bin. Length, width and the depth of grain.
Grain pile. A cone-shaped pile: the width across the base (measure two ways and average if it's lopsided) and the height at the top. A long pile with a ridge: its length, its width across the base and the height at the ridge.
Grain bags. Use the bag maker's bushels per foot, or the weight if it was weighed going in, as "Bags or other storage".
Why by field
SCIC asks for "detailed net production, accounting for weight, dockage and grade by individual field", and MASC asks field by field too. Give each bin the field or fields it came from and the totals split by field; add each field's seeded acres and you get its yield in bushels per acre.
Keep what's stored and what's delivered apart, as the reports do. For grain delivered, the net on your tickets, after dockage. For grain in storage, the bins' measure. MASC asks for stored grain as each bin's volume in bushels, with its test weight, dockage and grade, and does the test weight conversion itself, so each bin shows its bushels by volume as well as by weight.
Questions
When is the production report due?
Nov 15 in Saskatchewan (SCIC's Crop Production Declaration) and Alberta (AFSC's Harvested Production Report for annual crops; accepted late to Dec 31 with a penalty), and Nov 30 in Manitoba (MASC). If SCIC's isn't filed, the annual yield is set at zero and future coverage drops 10% for each year not reported. See the fall deadlines.
Which bushel does this use?
The imperial bushel AFSC uses in its published method: cubic feet × 0.7786. Bin makers often quote US bushels of 1.2445 cubic feet, about 3% more per bushel, which is why a bin's rated capacity in bushels can read higher than this.
How are tonnes worked out?
With the grain's test weight in kg/hL (from the elevator's grade or a hand tester), tonnes are the volume times that weight. Without it, each bushel counts at the crop's standard weight (wheat 60 lb, canola 50 lb, barley 48 lb, oats 34 lb), an estimate the table marks. No allowance is added for grain packing down in a tall bin.
Sources and method
Volumes: Agriculture Financial Services Corporation, Determining Production in Storage: a round bin is C × C × D × 0.07958 cubic feet (the same as π × radius² × depth), a rectangular bin L × W × D, a cone-shaped pile D × D × H × 0.31416, a long pile L × W × H × 0.5, a hopper bin a round bin above the pile formula for the hopper, and cubic feet × 0.7786 is bushels. AFSC's 0.31416 gives 20% more than a geometric cone (D × D × H × 0.2618); this uses AFSC's figure as published. AFSC gives no formula for a peak on top or a coned-down top, so those are geometric cones, ⅓ × π × radius² × height.
Weights: the standard bushel weights on bushels to tonnes; a tonne is 2,204.62 lb.
Reports and dates: SCIC, AFSC and MASC's own pages, read 24 October 2026. Your bins are sent to GrainPosition's server to add up and aren't stored there.
Were you paid right on your last grain settlement?
Send me a photo of the settlement, and the contract if you have it. Within a day I’ll email you back what each line is, what’s worth asking the buyer about, and any grade or payment deadline that’s still open. Free, no account.
