Tap the field. See where it ponds, where it dries out, and a free planting map that pulls seed off those spots. Takes a few minutes.
Built by Daniel Knutson, 17, who farms with his family near Meservey, Iowa. Free, no account.
Then tap the field on the map. We pull the boundary for you, no file needed.
A boundary export, a yield map or a planting map: a zipped shapefile, GeoJSON or KML. Read in memory and dropped. Only the outline you confirm is kept, the same as a tapped one.

Boundary from USDA crop sequence data. Drag a corner if it's off.
Drag a white corner to move it. Drag a small grey handle to slide that whole edge. Double-click (double-tap) a corner to remove it. Click the outline to add a corner.
More than one parcel? Tap inside one to work on its corners.
That is a big outline. Check the edges carefully, then drag a corner or cut it back before continuing.
Fill in: part of your field outside the outline, or a hole in the middle that shouldn't be there? Tap it, as many times as it takes. Separate parcel: ground you plant with this field but across trees, a creek or a road. The gap stays out of your acres.
The outline takes in ground across a fence line, a grass strip or a crop change more often than we can catch. Click along the line you can see on the photo, from outside the field to outside it. Double-click or press Enter to cut; the side you tapped is kept. Esc to stop.
We couldn't find a boundary where you tapped. Click the corners of the field, then click the first corner again to close it.
Reading the soil survey and the elevation model...
We can't see tile. If a low spot is tiled, it may not pond.
Every summer of satellite since 2017, checked against this field: where it held water, where it dried out, and a planting map built on all of it. It takes a few minutes. Put in your email and I'll send you the link and the PDF.
