I conducted the experiment in Central Ukraine's chernozem, a humus-rich dark soil. Ivan Gumeniuk,
innovations director at one of the local farms, helped me organize the project. We conducted an experiment at this same farm last year, in which we tested variable-rate fertilizer application.
This experiment contained two tasks: determining whether variable-rate seeding would affect the corn yield, and testing how different hybrids would react to this same seeding method. I chose two fields with similar chemical and physical properties to keep other factors from affecting the results.
