Crop and Weather Report - September 14

September 15, 2009

By Doug Cooper, Extension Communications specialist

Guests for the weekly crop and weather report Sept. 14 are ISU Extension climatologist Elwynn Taylor, integrated pest management specialist Rich Pope and corn agronomist Roger Elmore.

With harvest is just around the corner, Taylor says an arctic cold front is heading into the U.S. from Canada, and he doesn't think it will have any significant impact on Iowa. Mason City is the furthest behind in growing degrees days from normal of any site measured in the Corn Belt.

Studying Stover Harvest Effects on Yield, Soil, Climate

Planning fall fertilization activities should include giving consideration to soil sampling, and application of phosphorus and potassium, nitrogen, and manure.

Weekly Crop and Weather Report

August 25, 2009

By Doug Cooper, Extension Communications

Iowa State University Extension climatologist Elwynn Taylor, integrated pest management specialist Rich Pope, and soybean agronomist Palle Pedersen are the Aug. 24 weekly crop and weather report guests.

Taylor says the ocean's temperature is reported to be the warmest since 1909 and that could lead to an increase in tropical storms. These are storms that could impact Midwest weather patterns.

Pope repeats his recent message - late season crop diseases are being reported and scouting is still recommended.
