Crop & Scouting Update

  • Many fields are showing signs of drought stress, where beans have flipped over their leaves to reflect more sunlight and conserve moisture. Drought conditions can also results in plants moving through development stages more quickly and result in shorter plants with smaller leaves. Nodule growth and development may also be impacted, with fewer larger nodules observed on drought-stressed plants. These larger nodules are more resilient to drought stress, but N fixation may be reduced. Peak water uptake for soybeans is at flowering (R1-2), but the most critical time for water uptake is at pod initiation (R3-4) and seed fill (R5-6) stages. Water limitations may also impact nutrient movement into the plant, resulting in deficiency symptoms. Water limitations in pulse and soybean crops →
  • Several fields are also re-growing from previous hail damage. Now that the crop is at the R3-4 growth stages, hail damage at this time is expected to have a greater impact on yield and maturity than earlier storms. Yield loss estimates due to defoliation and node breakage from hail →
