  abstract = {{T}his study aims to evaluate the effect of land cover type, soil properties, and vegetation structure on fine root biomass, and examined how these factors affect diameter of fine roots. {T}he study was conducted in communities located in the {N}ova {I}pixuna, {P}arauapebas and {P}acajá municipalities of {P}ará state. {I}n each area, nine farms were selected; in each farm were sampled five plots, totaling 135 plots distributed into nine different types of land cover; at each plot, four soil samples were collected to quantify the fine roots, vegetation cover was inventoried, and soil was collected for physical and chemical characterization. {F}ine roots were separated into four different classes. {P}rincipal {C}omponent {A}nalysis ({PCA}) were done for the soil and vegetation matrix and they were compared with the fine root biomass {PCA} through a co-inertia analysis. {V}ariability was high for fine root biomass data. {A}ll land covers exhibited a high proportion of fine roots > 1 mm. {T}he co- inertia analysis showed that the fine root biomass {PCA} share a common structure with vegetation {PCA}, with 37/100 of the variability being explained; however only 9/100 of the variability was explained by the soil {PCA}. {O}ur results highlight the importance of roots with diameters < 2 mm for the quantification of root biomass, whereas the biomass of roots > 2 mm was critical to the differentiation among land covers.},
