      abstract     = {The pore size distribution (PSD) of biopolymeric-amended
                      soils is rarely investigated due to difficulties in its
                      quantification using classical methods. In this study, we
                      analyzed the impact of biopolymeric soil amendments on the
                      PSD of a dryland loamy soil based on its physical and
                      biological properties using a completely randomized design
                      with four treatments consisting of two different dosages (10
                      and 5 g kg−1) of two different biopolymers, (chitosan [CH]
                      and Arabic gum [AG]) plus a reference soil. To determine the
                      effects of CH and AG on the PSD, nuclear magnetic resonance
                      relaxometry (NMRR) measurements were used to determine the
                      longitudinal (T1) and transversal (T2) relaxation times. A
                      set of soil structure–related characteristics was also
                      determined in the laboratory. The results revealed that T2
                      spectra provided a good proxy to determine the PSD, showing
                      good agreement between the PSD from T2 spectra and that
                      calculated from the water retention curve (WRC) (R2 > 0.78;
                      RMSE <1.38 μm). The application of CH also increased the
                      zeta potential of the soil to −18.5 mV, compared with
                      −20 mV obtained for the reference soil. The WRC
                      measurements revealed that AG decreased the available water
                      content for plant use compared with the reference soil,
                      whereas CH increased the available water in comparison to
                      the reference soil. Considering the parameters of the van
                      Genuchten model, the application of AG and CH mainly
                      affected the parameter α, confirming the dominant changes
                      in macropores. This finding was confirmed by NMRR relaxation
                      spectra. Furthermore, the application of CH and AG
                      stimulated the microbial activity of the amended soil,
                      leading to an increase in soil respiration.},
