Wheat Production Data Maps

The Wheat Production Data for the 2009 Harvest Survey is presented using three different maps representing three characteristics of wheat: Moisture, Protein Content and Test Weight. NOTE: The maps will be updated on an ongoing basis to reflect current data. Please continue to check the site for the latest data available. Four additional maps are also available. The Projected 2009 Wheat Production Map, 2008 Wheat Quality Maps and the Five-Year Production Data map representing a five-year historic measurement of this data.

"Moisture1is an indicator of grain storability. Wheat or flour with high moisture content (greater than 14.5 percent) attracts mold, bacteria, and insects, all of which cause deterioration during storage. Wheat or flour with low moisture content is more stable during storage." Click here for the 2009 Harvest Survey Map:Moisture.

"Protein Content 2 is a key specification for wheat and flour purchasers since it is related to many processing properties, such as water absorption and gluten strength. Protein content also can be related to finished-product attributes, such as texture and appearance. Low protein content is desired for crisp or tender products, such as snacks or cakes. High protein content is desired for products with chewy texture, such as pan bread and hearth bread." Click here for the 2009 Harvest Survey Map: Protein.

Test Weight is reported as pounds per bushel. It provides a rough estimate of flour yield potential in hard winter wheat. The presence of dockage, foreign or shriveled kernels, or kernels that have swollen after recent rain can result in lower test weights. Click here for the 2009 Harvest Survey Map: Test Weight.

Projected 2009 Wheat Productionmap provides production estimates for the growing regions of Kansas. Please click to view the Projected 2009 Wheat Production Map.

2008 Wheat Production Data maps for Kansas are available by clicking here for 2008 Protein and 2008 Test Weight.

Five-Year Production Data represents the data for all three of these characteristics within a five year period. This data is available by county. Please click here to see the map for 5-Yr Production Data.
