South America Crop & Weather Update – May 06, 2026
(Using 15-day Satellite and Rainfall Estimate – Preferred Areal metric)

Mato Grosso Soybeans (15-day Satellite and Rainfall Estimate 100.0% → soil moisture near/above normal): Recent rain negligible last 24h. late vegetative. Moisture levels remain generally supportive for finishing soybean harvest and early Safrinha corn development, though below-normal 15-day POA suggests monitoring drier pockets. Forecast: 1-5d: 0.04 in (3% of normal, 0% cov) | 6-10d: 0.04 in (2% of normal) | 11-15d: 0.16 in (5% of normal)

Córdoba / Rosario Corn-Soy (15-day Satellite and Rainfall Estimate 100.0% → soil moisture near/above normal): Recent rain negligible last 24h. Corn in grain fill / early harvest (north); Soybean late reproductive / pod fill. Forecast: 1-5d: 0.76 in (114% of normal, 100% cov) | 6-10d: 0.02 in (2% of normal) | 11-15d: 0.00 in (0% of normal)

Santa Fe / Entre Ríos (15-day Satellite and Rainfall Estimate 100.0% → soil moisture near/above normal): Recent rain negligible last 24h. Corn and soybean in reproductive to grain-filling stages. Forecast: 1-5d: 0.62 in (87% of normal, 36% cov) | 6-10d: 0.28 in (20% of normal) | 11-15d: 0.77 in (36% of normal)

Buenos Aires Wheat (15-day Satellite and Rainfall Estimate 100.0% → soil moisture near/above normal): Recent rain negligible last 24h. Wheat harvest complete; Corn/Soy in reproductive / early maturity. Forecast: 1-5d: 1.01 in (173% of normal, 79% cov) | 6-10d: 0.02 in (2% of normal) | 11-15d: 0.03 in (2% of normal)

Northern Argentina Corn (15-day Satellite and Rainfall Estimate 100.0% → soil moisture near/above normal): Recent rain negligible last 24h. Corn advancing through grain fill; harvest beginning in earliest fields. Forecast: 1-5d: 0.00 in (0% of normal, 0% cov) | 6-10d: 0.00 in (0% of normal) | 11-15d: 0.00 in (0% of normal)

Bottom line: Strong short-term moisture support across key areas. Focus remains on Safrinha corn vegetative and early reproductive stages in central Brazil.
