Soybeans

Five Tips for Late-Planted Soybeans

By Bryan Olivi

Soybean planting is in full swing in the South and ramping up in the North. That said, because of one of the wettest springs on record, many parts of the country had to delay soybean planting. To help protect your investment and maximize yield, here are five tips to keep in mind for late-planted soybeans.

 

  1. Seed Quality

    Soybean seed quality is a hot topic for the 2019 season. These issues stem from environmental conditions arising in 2018 and have led to a limited soybean supply and lower quality seed germination. If germination is lower than 80%, increase your planting population to account for any loss of seed. Seed treatments will not increase the germination percent of soybeans in a bag, but do protect viable seeds and aid in proper emergence. Choose seed varieties with good tolerance to diseases and use seed treatments as a foundation to ward off additional infections.

     

  2. Soil Conditions

    Planting late-season soybeans, especially in warmer climates with drier soil conditions, may delay emergence if soil moisture is inadequate. To ensure proper absorptions and to encourage early sprouting, plant in moist soil. If moisture is too deep in the soil, plant near or after rain events. Soil deficiencies and soil-borne disease can be a hindrance to soybean emergence and crop yield. Poor drainage, dry soil and your field’s history are all important items to watch closely and know throughout the planting season. In regions with moist soils, Innvictis Crop Care Revize® PBI seed treatment offers good control of common soybean diseases.


  3. Planting Depth

    In sandier soils, target a one-and-half to two-inch planting depth, but do not plant deeper than two inches. When planting in heavier clay textured soils, one to one-and-a-half-inch planting depth is recommended.

     

  4. Weed Management

    Once rain occurs, small-seeded grasses and broad-leaves present in the fields may often emerge quicker than the soybeans. Late planted soybeans will canopy the rows quicker, however this occurs later in the growing season. Narrow row spacing is often recommended on late-season soybeans to ensure quicker canopy closer and help decrease weed pressure. Follow the planter with a good herbicide program that offers long-lasting residual control, such as Innvictis Crop Care’s Visor® S-Moc or Galvan® herbicides.

     

  5. Disease and Insect Pressure

    Soybeans planted later in the season are prone to increased insect and disease pressure. It is crucial to catch a disease before it spreads. To mitigate, actively scout soybean fields and check for insect damage on leaves, stems and pods. Bean leaf beetles, stink bug species and lepidopteran pests are common yield robbers for late-season soybeans. Use a proper insecticide management strategy to protect soybean yields. In humid climates, soybeans are especially susceptible to foliar diseases. Use a proactive scouting approach and apply fungicides in a timely manner to protect your investment.
