1. The product that I want to test cannot be done by NIR. Which wet chemistry test package should I order?   Package D offers OARDC energy calculation for most alternative feedstuffs and commodities, feed and forages. Feeds that have a defined and relatively narrow range of AD-ICP and Lignin values allow book values of these nutrients to be used in energy calculations.  Therefore, use Package D to analyze these materials.

Some feed can only receive OARDC energy calculations with analysis from Package D1 because they are not uniform enough to utilize book values for AD-ICP or Lignin.  For complete information on which feed and package combinations are required for the most common use objectives, visit Choosing Analytical Package for Alternative Feedstuffs

2.  How do I take a sample on the farm? Sampling technique can be found for Feed & Forage, Molds & Mycotoxins, Nitrates, Soil and Water can be found in the “Sampling Tips” pages under each service area. 

3.  How much sample is needed for testing? Most feed analyses require approximately 1 pint to 1 quart of material per sample.  Particle size analyses including: Corn Silage Processing Score, Forage Particle Size, Grain Particle Size, and Fermentrics, generally require 2 quarts of material per sample.

Dairyland provides soil test kits for various applications like Wildlife Food Plots, Lawns, and Gardens. Each kit contains a sample bag of the appropriate size. Dairyland provides water sampling kits with the appropriately sized containers.

4.  How long will tests take in the lab? NIR analyses are generally available the same day that samples arrive at the lab.  Many wet chemistry analyses, including Packages A-D and mineral analyses, take 2 or 3 days in the lab.  Most other wet chemistry analyses take 3-5 days.  When widespread outbreaks occur, nitrate analysis may be available same day while toxin analyses may be available in 2 days.

Soil analyses take approximately 3 days once sample has arrived in the lab. Water analyses take 1-2 days in the lab.

5.  Which toxins should I request? Determining which toxin to test for depends on the crop, suspected problems and environmental conditions.  Here are a few common toxins:


 Crops affected: Corn, corn silage, peanuts, cottonseed, other cereal grains

Conditions favoring production: Heat and drought stress pre-harvest.  Heat and humidity post-harvest.

Vomitoxin (DON)  

Crops affected: Cereal grains and their corresponding silages, including corn and corn silage. Also alfalfa and grass silages.

Conditions favoring production: Rain and warm weather from flowering to harvest in corn and small grains.  Low temperatures following infection may increase DON production by Fusarium molds.  DON is also associated with Gibberella ear rot.


Crops affected: Corn, wheat, alfalfa, and grass crops.

Conditions favoring production: Cool, wet weather.  After infestation with Fusarium mold, warm conditions promote more mold while cool conditions promote more Zearalenone toxin.  Growth occurs more often in storage than in the field.

T-2 Toxin

Crops affected: Corn, small grains, alfalfa, grass, and rice crops.

Conditions favoring production: cool and wet weather.

6.  Do I need an account before sending in samples?  Accounts are not required to submit samples, but they do make reporting and billing much easier.  To submit a sample without an account, please include payment with the sample submission.  This can be done with check or credit card information. Samples submitted without an account will not be analyzed until payment is received.

7.  Can I pay by credit card over the phone?  Yes. To pay by credit card over the phone please contact Dairyland’s corporate office (608-323-2123).

8.  What does the customer need to send a sample in? Feed sample submission requires the use of a Feed Card to submit a sample.  For customers that do not have an account, please include your name, address, phone number, and email address.  Dairyland also provides free postage-paid shipping by USPS and UPS for feed samples in the contiguous United States.  Shipping supplies can be obtained by contacting us here.

Soil sampling kits are available for Wildlife Food Plots, Lawns, and Gardens.  These contain pre-paid USPS mailers and can be obtained by contacting our corporate office (608-323-2123) or email us here

Conventional soil analysis requires a soil information sheet (linked).  For groups of 6 or more samples Dairyland will provide free postage-paid UPS labels which can be attached the outside of your shipping container.  All soil sampling supplies including information sheets, sample bags, and UPS labels can be obtained by contacting our corporate office (608-323-2123) or email us here.
