Guidelines
for Submitting Samples to the Agricultural Service Laboratory
April 9, 2007
Submit
all Plant Problem Clinic and Nematode samples to this address:
Plant Problem Clinic & Nematode Assay Laboratory
Submit all Soil, Feed and Forage, Animal Waste, Plant Tissue, and Irrigation Water samples to this address:
Agricultural Service Laboratory
Use
the lab supplies for submitting all samples.
Go to
http://www.clemson.edu/agsrvlb/ for
a list of lab supplies.
Horry
and Marion counties must use proper bags for all samples to contain witch weed.
Soil
Samples: Individual soil bags must be
filled to the fill to line with soil.
Label the bag with the sample number, name and address information, and
crop. Make sure sample matches with
form. Make sure to include account
number, soil code, crop codes, and desired analyses on form. Fill shipping box completely with individual
samples so the bags won’t move around during shipping. Use newspaper if needed to fill empty
spaces. Double-check and make sure the
forms in the shipping box match the samples.

for more details.
Plant
Tissue Sample for Nutrient Analysis: Submit clean undamaged leaf
tissue in a paper bag. Submit at least a
half a lunch bag full of tissue. (Submit
at least 25 large petioles or 50 small petioles for NO3-N analysis). Label bag and make sure form matches with
sample. Be sure to include account, crop
code, and desired analysis on form.

for more details.
Feed
and Forage Samples: Submit about a quart of
sample in a plastic bag. Mailers
containing bags and forms are available.
Make sure form matches bag. Be
sure to include account, animal type, feed type, and analyses desired on the
form.

for more details.
Irrigation
Water Samples: Submit about a pint of water
in a plastic bottle. Plastic drink
bottles work best for this. Fill bottle
completely. Make sure form matches with
sample. Be sure to include account and
analyses desired on the form.

for more details.
Animal
Waste Samples: Bags and bottles are available for use for solid and liquid waste
samples. Our lab bags must be used for
submitting solid samples to the lab. Do
not use any other bags for submitting solid waste samples. About a cup of liquid is required for liquid
samples. Make sure forms match samples. Be sure to include account, manure type,
storage, and analyses desired on the form.

for more details.
Nematode
Samples: Soil for nematode assays
should be neither too wet nor too dry. Do not allow the soil to become
overheated or dry out. Place a pint, i.e. 2 cups, of
soil in the sample bags provided, and label each sample. Separate
soil samples from both affected and non-affected locations will give a better
indication of population distributions in a field, but aren't absolutely
necessary. Limit the weight of sample boxes to 20 - 30 pounds.
Plant
Problem Clinic Samples: Clinic samples for plant
problem diagnosis or plant identification should be submitted in plastic bags
without adding any additional moisture. For plant identifications, submit
an entire branch or stem and include flowers or fruits, if present. For plant
problems, select as much recently affected plant tissue as possible. If
plants are exhibiting wilting, yellowing and general decline, submit the entire
plant, if possible. If not, a handful of fine feeder roots should be
collected from around the affected plant(s) and submitted in a separate plastic
bag from the aboveground sample. Fruits and other fleshy organs should be
wrapped dry paper prior to being placed in a plastic bag. Often, such
samples can be wrapped and placed in a box, without a plastic bag. Insects to
be identified should be placed in vials and enough rubbing alcohol added to
fill the vial. Send all samples in crush proof containers with enough
packing material to prevent sample damage during shipment.
