Overview

• BCR’s GEA network logged a regional August average of 193 mm versus a 30 mm norm, with peaks such as María Teresa at 344 mm, a “black swan” event in local records.
• Field access is constrained, with technicians estimating 5–10 days before many growers can start early maize sowing, and some hectares may shift to late maize or soybean in severely affected sectors.
• Impacts are uneven, with faster drainage in western districts while eastern and southern corridors—especially from Junín south between Routes 7 and 5—report persistent waterlogging and localized losses.
• BCBA reports wheat largely stable (98% normal to excellent) despite 27.3% of area showing excess moisture in the east and south, where fungal disease pressure is rising and timely fungicide applications are challenged by poor ground conditions.
• Strong nitrogen losses from leaching and denitrification are cited, with refertilization seen as uneconomical at current stages; short-term forecasts point to a dry, colder first third of September with frost risk, while a neutral Pacific and warm Atlantic keep spring rainfall uncertainty high.
