    Abstract

    The objectives of this study are to investigate the potential impact of indigenous mycorrhizal in andisols in influencing the reduction of P fixation, and efficiency of P fertilizer application. There were 3 years reasearch. The first year to investigate the population of mycorrhizal spores and P fixation reduction. The second year to study the effieciency of P fertilizer application, and the third year to study the inoculation to andisols. Results showed that number of indigenous mycorrhizal spores effects to reduced P fixation in the soil. Highest corn production achieved with optimum dose of 60 kg P ha1 when applied in soil with high number of mycorrhizal spores. Soil with high number mycorrhizal spores, reaching the highest production of potato tubers on the dose of fertilizer P equivalent to 30 kg P ha’. Results of inoculation showed that there is no effect of mycoorhizal inoculation for potatoes production in andisols.
