ZAMORA-MORALES, Bertha P. et al. Scientific research in Mexico: sequestration of organic carbon in agricultural and grazing land. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.1, pp.155-164. ISSN 2007-0934.  http://dx.doi.org/10.29312/remexca.v10i1.1733.

Organic carbon (CO) is related to the sustainability of agricultural systems, whose activities under inadequate practices degrade soils. This work had the following objectives: to know the trend of scientific research in Mexico, related to the capture of CO in agricultural and grazing lands; and propose lines of study that respond to current knowledge needs. A systematic review was made in online databases and in the physical and digital collection of institutions that study the subject, period 1990-2016. The 79 publications were compiled, mainly scientific articles (64.6%) and theses (29.1%), with a notable increase towards the last decade. The CO was estimated basically with analytical techniques, computational models and mathematical methods. The studies included several approaches: warehouse estimation; fertility; carbon dynamics; impacts of soil conservation practices and changes in use. The Postgraduate School stood out among the institutions that study the subject, for its number of investigations. Also, the state of Mexico and Tabasco for the studies carried out in their territories. The research was disseminated in national (59.6%) and international (40.4%) media. The National Council of Science and Technology and the Mexican Carbon Program, as well as the international commitments that Mexico has acquired in the area of climate change, have supported and reoriented research on the subject that it occupies. Study lines were proposed, among them: the standardization of analytical methodologies, indicators of CO capture and CO2 emissions.
