US soyabean futures slipped to a two-week low early on Tuesday, falling for a fifth consecutive session on quicker-than-expected harvest progress and selling before closely watched crop reports. Corn rose slightly but remained close to the six-week low touched on Monday, with the market remaining cautious before the US Department of Agriculture issues supply-demand estimates on Wednesday that will give a clearer picture of the impact from the worst US drought in 56 years.
Wheat edged higher with corn, as traders factored in declining expectations for production in Australia and the Black Sea region, key global exporters struggling with dry weather. Chicago Board of Trade new-crop November soya was down 0.3 percent at $17.14 a bushel by 9:15 a.m. Central time. December corn edged up 0.2 percent to $7.85 a bushel, not far from Monday's six-week low of $7.81. CBOT December wheat rose 0.7 percent to $8.95-1/2 a bushel.
