MADRIGAL REYES, Susana; CRISTOBAL ACEVEDO, David; HERNANDEZ ACOSTA, Elizabeth  and  ROMO LOZANO, José Luis. Influence of cover, slope and depth, on soil carbon and nitrogen. Rev. mex. de cienc. forestales [online]. 2019, vol.10, n.51, pp.201-223. ISSN 2007-1132.

The joint study of soil organic carbon (COS) and total soil nitrogen (Nt) is important because their cycles interact, they are also considered parameters of fertility, quality and impact. Its contents in the soil affect the productivity of the forests and are related to the mitigation of climate change when the soil is conserved. Soil sampling was carried out in the Zoquiapan Experimental Forest Station, with the aim of obtaining and analyzing the content of SOC and Nt of the soil at 0 to 10, 10 to 20 and 20 to 30 cm deep, with three slope degrees where fir, pine and pine-alder forests grow. The largest COS and Nt simks were located in the first 10 cm. The soil with the fir cover, greater slope and lower depth had the highest COS and Nt content (132.20 and 14.19 Mg ha-1 respectively). The soil with pine cover, slope and greater depth had the lowest contents of COS and Nt (30.86 and 3.37 Mg ha-1, respectively). It is concluded that the contents of COS and Nt showed differences by type of coverage, slope and depth. Although it was in relation to the depth that the contents of COS and Nt had a more regular behavior, decreasing as the depth increased, regardless of coverage and slope.
