the normal sample, you know that there is still some product in the rootzone that will adversely affect grass growth. Results from this test should be available to you within 7 days.
If you have noticed a discolouration to the sward but are uncertain as to whether the turf has been damaged, it may be worth taking a couple of small, 2cm diameter core samples from the affected area, sealing them in a plastic bag and storing them in a freezer. These samples can be kept for months if necessary and, if the cause of the problem does eventually need to be identified, they can be sent to a suitable laboratory for analysis. In the natural turf situation, applied products, including pesticides, will be broken down over time and if material has not already been taken and frozen (or already sent to the laboratory for analysis), it may prove impossible to detect the cause of the damage. If you suspect damage or vandalism and don’t want to wait and see what may happen to the sward over time, you can send material straight away to a chemistry laboratory such as Mountainheath Services Limited, Hertfordshire, where they can analyse plant tissues and rootzone samples to identify or monitor levels of chemical contamination. If you are going to do this, send the material to the laboratory as quickly as possible, as soon as damage is suspected (or send your stored, frozen material) and, depending on what is being analysed for, it is often possible to
get same day turn around of results. This could be crucial to the rapid recovery of the playing surface. Again, speak to someone at the laboratory, explain the problem and they will advise you on the most appropriate type of sample to be sent for analysis and the quantity required. Knowing who you can turn to for help if something does go wrong, should offer peace of mind. Regardless of what analysis you are seeking or where you are sending material for analysis, make sure that you label the samples appropriately so that when you receive the results, you can relate them to the turf area that was sampled. Also, don’t forget to enclose your contact details so that the results can be sent out to you. You may smile at this, but you would be surprised how often it is necessary to ‘match up’ samples received to persons having sent material for analysis. This variety of turf and rootzone analyses is offered to you by a number of laboratories to help you in your position as a turf manager. They should be considered as another tool for you to use to help you make informed decisions about your maintenance programme, but they can only be helpful to you if the correct sample material is sent for analysis. If in doubt, ask.
