How To Take A Plant Sample...

Follow these basic guidelines to ensure a good plant sample is received by the lab.  Pull portion of plant needed using the chart below and place leaves in a Plant Sample bag or paper bag.  Do not use a plastic bag.  Wash contaminated samples gently with water if needed.  When possible, collect a soil sample from the same location the plant sample was taken.  Fill out the information sheet as completely as possible, including crop, stage of growth, and sample number.  Be sure the sample numbers of the information sheet correspond with the numbers on the sample bags. The following chart shows field crops and the proper part of each plant to sample and send in.

Plant Sampling Chart for Field Crops

Clover Prior to bloom Mature leaf blades about 1/3 of the way down the plant 50-60
Corn Seedling stage All of the above ground portion 25-30

 IF SAMPLING INSTRUCTIONS ARE NOT GIVEN FOR THE CROP YOU WISH TO SAMPLE, A GOOD RULE OF THUMB IS TO SAMPLE THE YOUNGEST FULLY MATURE LEAVES
