Plant tissue analysis can be used as a guide for determining the cause of poor crop and pasture performance, however accurate sampling is just as important as the laboratory analysis. East West EnviroAg can also test for boron, molybdenum, cobalt, chlorides, soil-total N & P and cotton petiole NO3. Prices for these additional tests will be discussed on submission of samples. 1.Select the area to be sampled. Preferably sample early in the morning and send samples on the same day. Do not sample plants that have been recently sprayed, that are diseased or covered in dust. Do not sample in extreme climatic conditions, or after irrigation or heavy rain which may cause water logging of the soil. 2.You will require clean sampling equipment such as stainless steel scissors, PAPER sample bags and a pen to label bags. Wash your hands thoroughly before sampling or wear a clean rubber glove. 3.Collect the minimum number of sub-samples for each sample as identified in the following tables for the varying plant types. Document the site and crop information on the analysis form on the back of the envelope provided. 4.After collecting the sample, mark identification details on the paper bag so that you know where it came from. This identification will be the one we use when returning your results to you. Store samples in a cool place such as an esky or refrigerator between sampling and posting. Post samples ASAP.
