On farm strip trial, 5 farms, 150 strip seasons
Field trial poster example
A field trial poster reports a treatment applied on working land, so it needs the layout, the replication and the yield in one place. This A0 landscape example spreads biochar at 0, 5 and 10 tonnes a hectare in 75 strips on five New South Wales grazing farms for two seasons. Pasture rises from 5.1 to 5.8 t a hectare, 14% at the high rate.
The whole board
The poster at full size, exactly as it prints. Every number, citation and caption on it was written for this example, so the layout is being judged on real content.
Block by block
What each block on the board is for, in the order a reader walks it.
- Title band and three authors
- The title asks whether biochar grows more pasture and names the rates, farms and seasons. Three authors from the fictional Gidgee Plains University in New South Wales.
- Column 1: abstract, introduction and references
- The abstract gives all three yields and the payback caveat. The introduction explains why the trial ran on working farms, and three references sit at the foot.
- Column 2: methods and strip flow
- Five method entries: farms, layout, seasons, measure and analysis. The flow goes from 7 farms approached to 150 strip seasons analysed, under the design's fixed PARTICIPANT FLOW heading.
- Column 3: key number, Figure 1 and yield by farm
- The stat block gives 14% more at 10 t/ha. Bars show 5.1, 5.6 and 5.8. The five farm table from the row is written as a section, since this layout has no table block.
- Column 4: discussion, key finding and cost note
- The discussion says the response flattens after 5 tonnes. The callout says the same in one line, and the four point checked list carries the cost and payback.
- Acknowledgements
- Thanks to the farms and contractor, the field team, and a funding note that says the supplier had no part in the trial.
What makes this board work
Replication you can count
5 farms times 15 strips is 75 strips, times 2 seasons is 150 strip seasons, 50 per rate. The method block and the flow state the same arithmetic.
Farm by farm, not just the mean
Every one of the five farms grew more at 5 t/ha than at none and more again at 10 t/ha. The farm rows average exactly to 5.1, 5.6 and 5.8, so the headline is not one good farm carrying four flat ones.
Agronomy and money on one board
The cost list turns 0.5 and 0.7 t of extra pasture into payback: 18 seasons at 5 t/ha and 26 at 10 t/ha at $250 a tonne of dry matter. A grazier reads the last column first.
Questions people ask
What makes a field trial poster different from a field study poster?
A field trial applies a treatment and compares it with a control on the same land, so it can speak to cause. A field study observes what is already there. This board spread biochar at three set rates in randomised strips, so its methods centre on layout and replication, not on site selection.
How should strip replication be shown on a poster?
As multiplication a reader can check: farms, strips per farm, rates, seasons. Here 5 farms with 15 strips each give 75 strips, 5 per rate per farm, and 2 seasons make 150 strip seasons. Put the arithmetic in one method entry and repeat the total in the flow or the stat detail.
Should yield be reported per season or as a total?
Per season when seasons differ, and say which. This board reports t of dry matter a hectare a season, averaged over two seasons and five farms. The wetter 2024 season grew 0.6 t more at every rate, and the results say the ranking of rates held in both.
Why does the chart axis not start at zero?
The figure sets its axis from the data, so bars of 5.1 to 5.8 t start near 4 rather than 0, which makes the gaps look larger than they are. The caption prints all three values, and the stat block gives the change as 14%, so a reader has the true size in front of them.
Where does a cost analysis go on a research poster?
In the last column, near the conclusion, because it answers the question the audience brings. This board uses its four point checked list for price, the cost at each rate and the payback period. Keep the assumptions visible, here $450 a tonne of biochar and $250 a tonne of dry matter.

Simulation study poster example
A simulation study poster must say what the model assumes as clearly as what it found. This A0 landscape example runs an agent based evacuation model of a 1,200 seat hall under four exit layouts, 500 runs each. Adding a fourth exit at the rear cuts mean clearance from 212 to 168 seconds, 21% faster, and the 95th percentile from 251 to 192. Four model limits sit right beside that headline.
Cohort study poster example
A cohort study poster has to show change over time in the same people, so the follow up waves carry the board. This A0 landscape example follows 2,400 hospital and factory workers for six years, 1,200 on rotating shifts and 1,200 on day work, and reports new hypertension with an adjusted hazard ratio of 1.5, 95% CI 1.2 to 1.9.
Case control study poster example
A case control study poster lives or dies on its exposure table, because every odds ratio has to rebuild from the counts beside it. This A0 landscape example compares 210 adults treated for kitchen burns with 420 controls matched on age across six exposures. Loose sleeves carry the largest odds ratio, 2.8, 95% CI 1.9 to 4.2.
