- INFLUENCE OF SUGARCANE BURNING ON SOIL CARBON AND NITROGEN RELEASE UNDER DROUGHT AND EVAPOTRANSPIRATION CONDITIONS IN A MEXICAN SUGARCANE SUPPLY ZONE DAVID E. FLORES-JIMÉNEZ MARCOS ALGARA-SILLER NOÉ AGUILAR-RIVERA NOEL CARBAJAL CRISTÓBAL ALDAMA-AGUILERA ALFREDO ÁVILA-GALARZA GREGORIO ÁLVAREZ-FUENTES Ciencias de la Tierra Water flux Soil quality Waste burning Meteorological events Sugarcane cultivation is an agricultural activity of worldwide importance. This crop has been cultivated in Mexico for centuries, impacting important productive areas like the study region called Huasteca Potosina which is located at the Central-East part of Mexico. The relationship between soil conditions, weather and production per hectare allows identifying the edaphological and climatic conditions (aptitude levels) for cultivating sugarcane in the study area. The objective of this research work is to analyze the relation between the cultivated hectares and production of sugarcane. Likewise, to explain its behavior and interpret the contribution of N and C released to the atmosphere for burning sugar cane in association with events and meteorological parameters involved in the flux of water between soil and atmosphere such as drought, evapotranspiration and rainfall. The methods and indicators for burning waste provided by the Intergovernmental Panel on Climate Change (IPCC), the value of potential evapotranspiration as Thornthwaite and drought severity index were applied in order to understand the correlations between the drought severity index and potential evapotranspiration, and between C and N release and potential rainfall availability. The results show the increment of harvested hectares and the loss of water from the soil by the increase of periods of drought events and evapotranspiration. The volatilized nutrients in soil varied from 1.32 × 105 to 2.17 × 105 t for C and from 1.32 × 103 t to 2.17 × 103 t for N during the burning of sugarcane, affecting production levels with values fluctuating between 38 t/ha to 77 t/ha for the term of 1990-2010. 2016 artículo científico 0188-4999 https://www.redalyc.org/articulo.oa?id=37045328004 https://www.redalyc.org/journal/370/37045328004/ https://www.redalyc.org/journal/370/37045328004/html/ https://www.redalyc.org/journal/370/37045328004/37045328004.epub https://www.redalyc.org/journal/370/37045328004/movil en http://www.redalyc.org/revista.oa?id=370 Revista Internacional de Contaminación Ambiental application/pdf Universidad Nacional Autónoma de México Revista Internacional de Contaminación Ambiental (México) Num.2 Vol.32
