In this work we use an eikonalized minijet model where the effects of the first nonlinear corrections to the DGLAP equations are taken into account. The contributions coming from gluon recombination effects are included in the DGLAP+GLRMQ approach for the free proton in the context of saturation models. The parameters of the model are fixed to fit total $pp$ and $\bar p p$ cross sections, including the very recent data from LHC, HiRes and P. Auger Collaboration. Glauber and multiple scattering approximations are then used to describe the inclusive inelastic proton-air cross section. Photoproduction cross sections, without change of parameters fixed before, are also obtained from the model using Vector Meson Dominance and the Additive Quark Model. We show and discuss the main results of this study as well as the implications of saturation effects in the behavior of total hadronic and photonic cross sections.
