Brazil's 2019/20 soybean planting reached 77.3% of estimated area as of the week ending November 22, up 6.4 points on the week but behind last year's 89.6% and the historical average of 80.5%, according to Arc Mercosul. Rio Grande do Sul lagged badly at 38% planted after excessive rain and then dryness, and dry weather was also flagged from southern Mato Grosso to northern São Paulo.
Delayed soybean planting pushes the new-crop harvest later and raises concern over the safrinha corn crop that follows, which tends to support soybean meal and corn prices if yield risk builds. Continued dryness would add modest upward pressure on soy complex prices.
