  • Soil test.

  • Apply lime as required

  • Use the manure on your corn acres.

  • Consider potash applications prior to the soybean crop…take care of corn needs now.

  • Use America’s Best Soybean Inoculants (ABM).

  • Plant early! Start planting soybeans one week or more ahead of your field corn.

  • Consider earlier group soybeans (3.0 instead of 3.6, or 2.7 instead of 3.3).

  • Strive to begin harvest in mid-September. Especially if wheat is part of the rotation!

  • No-till if you’re not doing so already!

  • Consider precision planting and lower populations…as low as 110 to 150,000/acre.

  • Like wheat, soybeans are only ready for harvest once, afterwards quality begins to decline.
