description	Damping-off and root rot are major diseases affecting seedlings of <i>Eucalyptus</i> species in forest nurseries in temperate regions in Argentina. The most common fungi associated with these diseases and affecting the vigor of the root system are <i>Fusarium</i> and <i>Pythium</i> species. Two forest nursery experiments were conducted in the province of Buenos Aires, Argentina, to determine the effect of soil solarization on growth of <i>Eucalyptus viminalis</i> seedlings and relate this effect to the presence of pathogenic and native ectomycorrhizae populations in roots and nutrient availability in soil. Changes in populations of soilborne pathogens were determined by a bioassay that relates their potential to induce disease. Changes in native ectomycorrhizae were assesed by measuring colonization levels in roots. Nutrient availability was determined by the amount of nitrates released by solarization. Solar heating decreased pathogenic and ectomycorrhizal inoculum potential and increased soil nitrates. Seedling growth in solarized seedbeds may be related to a low initial pathogenic population and/or to increases in nitrate availability. Solarization may induce soil suppressiveness against re-establishment of major seedling pathogens in treated soils.
