Biblical rain in Kazakhstan's major growing regions has cut wheat and barley production, reducing its quantity and quality. In the previous Kazakhstan Grain and Feed Report, Post warned that if the worst-case scenario of rains occurred during harvest, up to 10 to 15 percent of the barley and wheat crop could be lost. Post has revised the production estimate for wheat down from 15.8 MMT to 14.2 MMT and barley down from 3.4 MMT to 3.0 MMT, or 10 percent less than the August 20 estimate.
