LOPEZ BAEZ, Walter et al. Properties of soils coffee in the Biosphere Reserve El Triunfo, Chiapas, Mexico. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.3, pp.607-618. ISSN 2007-0934.

The low productivity of 12 000 hectares of coffee grown in the Biosphere Reserve El Triunfo (REBITRI), besides affecting the income of families represents the main threat of change in land use, loss of biodiversity and services ecosystem in the protected area by encouraging the opening of new areas of cultivation to compensate inefficiency. The damage caused by the recent rust disease has encouraged farmers to improve their farming practices, especially fertilization. The properties of soils in order to initiate a fertilization program that contributes to sustainably improve productivity levels were analyzed coffee. The results indicate a generalized acidity caused mainly by the H + in the soil solution, with no H and Al ions in colloids. The high content of organic matter they assume that acidic conditions are affecting their humification and mineralization. The CIC dynamics in soils is influenced by pH and organic matter content. Over 90% of the plots have high levels of K, Ca and Mg and content low P and B in 50 and 84%, in the latter could have response to the application of these nutrients. The Ca excess could be limiting the absorption of K and Mg and the Mn excess in the soil they could be associated with physiological problems to absorb and store.
