For more information contact: Tom Morris at 486-0637,
Richard Meinert at 626-6240, Joyce Meader at 774-9600,
Frank Himmelstein at 875-3331, or Dawn Pettinelli at
the UConn Soil Testing Lab at 486-4274.
1. Sample when corn is 6 to 12 inches tall or shortly before pumpkins begin to run:
a. Sample the surface 12-inch layer of soil.
b. Obtain 15 to 20 cores per sample area. If the
field to be sampled is larger than 15 acres, divide the field into 2 or
more sample areas
if it is convenient and feasible to do so.
c. Avoid row fertilizer bands (e.g., starter) by
sampling midway between rows. Avoid sampling areas where manure was
piled or
where manure application was unusually heavy or light.
d. Mix cores thoroughly in a clean pail; take 1
cup as the sample. Place sample in cloth bag, close, and make sure to write
name and
sample ID on yellow tag. Call the lab (860) 486-4274 about how to
obtain
cloth sample collection bags.
2. Use of the cloth bags eliminates the need to store
and transport samples in Styrofoam coolers. The use of cloth bags does
not eliminate the need to
protect moist soil samples from temperatures
above 75EF. SEE NEXT PAGE FOR ADDITIONAL INSTRUCTIONS.

| 3. Refrigerate samples if they cannot be analyzed within three days. Samples expected to spend more than three days without refrigeration should be dried as soon as possible. Samples can be air-dried by spreading in a thin layer - a fan will accelerate drying. |
| 4. Samples that are extremely wet or muddy should be dried before shipping or storage. Incorrect results will be obtained if water drips from the samples. |
| 5. Mailing samples usually poses no problem if samples spend no more than three days without refrigeration. There are two choices for mailing: the U.S. Postal Service's Priority Mail and the United Parcel Service (UPS). Both should provide overnight delivery within the state of Connecticut. United Parcel Service might be more reliable for overnight delivery because they deliver directly to the Soil Nutrient Analysis Laboratory. If UPS is used for shipment, it is preferable to ship directly from an UPS office. If an independent mailing service is used for shipment by UPS, make sure that the samples arrive before the UPS pick-up time. |
| 6. The UConn Soil Nutrient Analysis Laboratory will FAX the results and recommendations to you the day after receiving samples. If you do not have a fax machine, call the lab to make arrangements for receiving results in a timely manner. The results also will be mailed to each grower. |
We strongly recommend that you make every effort to obtain a 12-inch deep sample because our research data demonstrates that the most accurate recommendations are obtained from 12-inch samples. But if you cannot sample this deeply, please note the average depth of sampling (e.g., 8 inches) in the column provided. This information will be used to adjust your N recommendation. A higher rate of N will be recommended for most soils because nitrate concentrations normally decrease with depth. |
