It usually involves walking on a treadmill or pedaling a stationary bike at increasing levels of difficulty, while your electrocardiogram, heart rate, and blood pressure are monitored. Your doctor uses the stress test to: Determine if there is adequate blood flow to your heart during increasing levels of activity.
University of Illinois February 2018 This publication presents revenues and costs for producing corn, soybeans, wheat, and double-crop soybeans in three regions of Illinois: northern, central, and southern Illinois. Central Illinois is further divided into categories for high-productivity farmland and low-productivity farmland. Divisions between high and low farmland productivity are made based on soil productivity ratings. Generally, farms with higher soil productivity ratings have higher yields. Between 2011 and 2016, corn yields on high productivity farmland averaged 192 bushels per acre while corn yields on low productivity farmland averaged 179 bushels. This publication includes ten tables: 1. Corn Revenue and Costs, Northern Illinois 2. Soybean Revenue and Costs, Northern Illinois 3. Corn Revenue and Costs, Central Illinois with High Productivity Farmland 4.
We recently analyzed 16 years of data from a nitrogen rate study at Monmouth, Illinois. The observed best nitrogen rate for corn following corn ranged from 53 to 240 pounds of nitrogen per acre, depending on the year.The predicted best rate of nitrogen based on all 16 years of data was 147 pounds per acre, with a yield of 144 bushels per acre, or slightly more than 1 pound of N per bushel.he pounds of nitrogen per bushel of yield ranged from 0.6 to 2.1, and in only 2 years of the 16 did it fall within the range of 1.1 to 1.2 pounds N per bushel. The variability of these results did not surprise us; we've seen such swings in virtually every study we've conducted.
