Drivers of N2O emissions from natural forests and grasslands differ in space and time
Araujo, Patricia Ines; Piñeiro Guerra, Juan Manuel; Yahdjian, Laura; Acreche, Martin Moises; Alvarez, Carolina; Alvarez, C.R.; Costantini, Alejandro Oscar; Chalco Vera, Jorge Elías; De Tellería, J.M.; Della Chiesa, T.; Lewczuk, Nuria; Petrasek, M.; Piccinetti, Carlos Fabian; Picone, Liliana; Portela, Silvina Isabel; Seijo, Sebastian; Videla, Cecilia; Piñeiro, G. (Springer, 2020-06-30)Understanding the drivers of greenhouse gas (GHG) emissions is one of the most critical global environmental challenges to mitigate the increasing global temperature. Nitrous oxide (N2O) emissions are highly variable in ... -
Emisiones provinciales de gases con efecto invernadero del sistema suelo-caña de azúcar de Tucumán
Chalco Vera, Jorge Elías; Acreche, Martin Moises (Ediciones INTA, 2020-12)Las estimaciones de emisiones de gases con efecto invernadero (GEI) de suelos agrícolas informadas en el último Reporte Bienal de Actualización de Argentina en 2017 presentan gran incertidumbre debido a que se basan en el ... -
Greenhouse Gas Emissions from Green-Harvested Sugarcane With and Without Post-harvest Burning in Tucumán, Argentina
Acreche, Martin Moises; Portocarrero, Rocio; Chalco Vera, Jorge Elias; Danert, Fátima Carolina; Valeiro, Alejandro Hector (2014-06)Concentrations of greenhouse gases (GHG) in the atmosphere are increasing due to anthropogenic actions, and agriculture is one of the most important contributors. This study quantified GHG emissions from green-cane harvested ... -
Increases in nitrogen use efficiency decrease nitrous oxide emissions but can penalize yield in sugarcane
Chalco Vera, Jorge Elías; Portocarrero, Rocio; Piñeiro, Gervasio; Acreche, Martin Moises (Springer, 2021-11)Nitrogen (N) fertilization strategies focused on increasing nitrogen use efficiency (NUE) and decreasing nitrous oxide (N2O) emissions are important for sustainable crop production. In sugarcane, however, a joint assessment ... -
Integrating critical values of soil drivers for mitigating GHGs: An assessment in a sugarcane cropping system
Chalco Vera, Jorge Elías; Curti, Ramiro Nestor; Acreche, Martin Moises (Elsevier, 2020-02)Agricultural practices can reduce emissions of greenhouse gases (GHG). The definition of management practices toward mitigating GHG emissions could gain accuracy by integrating critical values of soil variables related to ... -
Long-term vinasse application enhanced the initial dissipation of atrazine and ametryn in a sugarcane field in Tucumán, Argentina
Portocarrero, Rocio; Chalco Vera, Jorge Elías; Vallejo, Juan Inosencio; De Geronimo, Eduardo; Costa, Jose Luis; Aparicio, Virginia Carolina (Wiley, 2023-12)The production of sugarcane bioethanol generates large volumes of vinasse, an effluent whose final disposal can produce an environmental impact that is of concern. The long-term disposal of vinasse in sugarcane fields could ... -
Physiological bases of genetic gains in sugarcane yield in Argentina
Acreche, Martin Moises; Saez, Julio Victor; Chalco Vera, Jorge Elias (Elsevier, 2015-04)Breeding and management efforts during the 20th century have increased sugar yield in almost all sugarcane areas worldwide. However, a close analysis of the trends during the last decades reveals that the rate of increase ... -
To burn or not to burn : the question of straw burning and nitrogen fertilization effect on nitrous oxide emissions in sugarcane
Chalco Vera, Jorge Elias; Valeiro, Alejandro Hector; Posse Beaulieu, Gabriela; Acreche, Martin Moises (2017)Nitrous oxide (N2O) is the main greenhouse gas emitted from farming systems and is associated with nitrogen (N) fertilizer application as well as decomposition of organic matter present in the environment. The objective ... -
Towards a baseline for reducing the carbon budget in sugarcane: three years of carbon dioxide and methane emissions quantification
Chalco Vera, Jorge Elias; Acreche, Martin Moises (2018-11)Sugarcane straw burning or removal and N fertilization are management practices that modify the input of carbon (C) to the soil affecting greenhouse gases emissions and the potential of the soil for C sequestration. This ...
