PropelMapper’s free calculators turn your sample counts and planning assumptions into a calculation you can explain.
Use any calculator without an account. Choose a topic, enter your own measurements and read the method before using the result in a client report.
You count plants in a measured row and use the stand-count calculator to work out plants per acre. The result describes that sample. The gaps and wet ground you saw around it belong in the explanation, too.
You can record the calculated result with the raw count, sample dimensions and location in a visit note. After upload, we put those notes into a report you read and add your advice to.
The calculator does the arithmetic from the values you enter. You decide what the sample means for the field and what recommendation the grower needs.
“Stand-count example: 32 plants in 17.4 feet of a 30-inch row. The calculation is about 32,044 plants per acre before display rounding. This sample is from the wet patch, so I am keeping it separate from the other counts.”
A count of 32 plants in 17.4 feet of 30-inch row gives about 32,044 plants per acre before display rounding.
This directed sample describes the wet patch and is kept separate from the other counts.

After your review
Keep the sampled area, units and method with your result. PropelMapper holds the visit notes and photos that explain the inputs you used in these calculators.
The visit report can carry the sample, units and assumptions alongside the calculated figure, so the grower can see what it describes.
