Abstarct: Due to the fixation of chemical fertilizers in soil and environmental pollution, use of the organic and biological fertilizers in order to release the on-farm resources of application of previous years which are unavailable can be a suitable alternative for chemical fertilizers and achieve to the sustainable agriculture. This study was performed to evaluate the effect of arbuscular mycorrhizal and organic fertilizers (vermicompost and humic acids) application on uptake and transportation efficiency of potassium in potato in a rich soil of potassium. For the purposes of this study, we selected a field with high concentrations of potassium and were done a factorial experiment in a randomized complete block design with three replications. Treatments was consisted of three levels of Vermicompost (0, 5 and 10 t/ha) and two levels of Humic acid and two levels of Mycorrhiza. Sampling was done in two stages 65 and 85 days after planting and the measured traits were include the concentration of potassium in leaves and tubers. Then By using of the relevant formulas, potassium uptake efficiency was also calculated. The results indicated that in both sampling, humic acid by potassium transfer from the above-ground to the underground part led to significantly increase (P<0.05) of potassium in underground part of plant compared to control. That this transfer leads to an increase in the number of tubers and reduce in the tubers diameter, stem dry weight and plant height. Also the effect of any one of the treatments were not significant on uptake efficiency of potassium of leaves and tubers. baxsed on the results of this study, By using of humic acid can supplied both directly and indirectly, The bulk of potassium needed by plants in alkaline soils and reduce environmental pollution especially surface waters to chemical fertilizers.
