All you need to do is select the analysis (maize or wheat) to the top right. You will find that you can select the required countries (maximum of 6 at a time) and the various tests that you are interested in. This will then be displayed as per your requests.

 

U selekteer die tipe analise (mielies of koring) bo regs. U sal vind dat u die verlangde lande (maksimum van 6 per keer) kan selekteer met die verlangde analises. Die data sal dan getoon word soos geselekteer.
