Soybeans in Argentina were 10.6% harvested as of late last week, which represented an advance of 8.7% for the week. The average nationwide yield thus far is 3,570 kg/ha (53.1 bu/ac), but the range in yields is quite wide. In the core production areas, the yields are in the range of 3,980 kg/ha (59.3 bu/ac), while in southern Buenos Aires, southern La Pampa, and north-central Cordoba, they are in the range of 2,520 kg/ha (37.5 bu/ac). The Buenos Aires Grain Exchange warned of potential declining soybean yields in northern Argentina, north-central Cordoba, western Buenos Aires, and northern La Pampa.
