Mato Grosso soybeans – planting and growth context – November 06, 2026
Soybean planting is nearly complete across Mato Grosso (roughly 90 % done statewide, with Médio-Norte essentially finished). The majority of the crop is in vegetative stages (emergence through mid-vegetative). Focus has shifted from sowing progress to stand establishment, early canopy development and the timing of the next rains. Safrinha remains off-season; the early finish is favorable for the January–February harvest window that sets up second-crop corn and cotton. Moisture is still running below normal for this stage of the calendar, so planting progress is uneven and remains closely tied to the next meaningful rain events. Through Nov 03, Mato Grosso averaged about 1.74" over 15 days versus a normal near 3.17" (~55% of normal); 30-day total near 4.21" (normal ~5.28", ~80% of normal); last 7 days ~1.24". Independent 30-day CHIRPS POA from the web product: 95% of normal (with forecast), 95% observed only.
AIFS-style outlook for Mato Grosso: days 1–5 ~0.53", days 6–10 ~0.94", days 11–15 ~1.85".

Argentina (from web product, if available):
Córdoba / Rosario: CHIRPS/web POA ~101% (obs ~101%); forecast 1–5d 0.73". Corn/soy reproductive to grain fill.
Santa Fe / Entre Ríos: CHIRPS/web POA ~90% (obs ~89%); forecast 1–5d 1.07". Corn/soy reproductive to grain fill.
Buenos Aires: CHIRPS/web POA ~82% (obs ~74%); forecast 1–5d 0.42". Wheat done; corn/soy reproductive.
Northern Argentina: CHIRPS/web POA ~71% (obs ~71%); forecast 1–5d 0.00". Corn grain fill / early harvest.

Bottom line: In Mato Grosso the story is soybean planting pace and early growth versus rainy-season moisture—use the past 7/15/30-day grid versus normal plus the next 15-day rains to judge whether sowing can broaden, stands establish cleanly, or progress stays staggered.
