How Fields Are Measured

January 11, 2010 09:31 AM
 

Stop every 20 to 25 miles along the marked route, (or once every county... gather about 15 samples per day) preferably where corn and soybean fields are side-by-side with no fences.

 
In Each Corn Field...
1. Record crop district and county.
2. Go 35 paces into the field to start sampling.
3. Measure row spacing and record.
4. Measure a 30 ft. plot, then count all ears in two rows in the plot. Record total.
5. Pull the 5th, 8th and 11th ear off one row of the plot.
6. Take corn ears back to car.
7. Measure length of grain on each ear, average and record.
8. Count number of kernel rows on each ear (will be even number), average and record.
 
 
In Each Bean Field...
1. Record crop district and county.
2. Walk as far into the field as possible without causing significant damage via your path.
3. Measure 3 ft. plot.
4. Count total number of plants in the 3 ft. row and record.
5. Randomly select three plants.
6. Measure row spacing and record.
7. Count all pods on selected plants and determine the average from those three plants.
8. Multiply the average pod count by the number of plants in the 3 ft. section and record. (Special Note: There will most likely be small pods on each plant. WE WILL COUNT ANY POD THAT MEASURES 1/4 INCH OR MORE.)
9. Rate soil moisture and maturity against the two indices (on back of soybean data sheet) and record.

  does your sampling process somehow adjust for kernal depth??
