La intensificación de la agricultura requiere altas dosis de fertilizantes nitrogenados, los cuales son transformados en el suelo mediante procesos biológicos (nitrificación–denitrificación), donde se ocasionan pérdidas de nitrógeno en lixiviados de nitratos (NO3 -) y emisiones hacia la atmósfera...
El suelo es el mayor reservorio de Carbono (C) en los ecosistemas terrestres, se estima que almacena cerca de 1500 gigatoneladas (Gt). Este C almacenado en el suelo, está relacionado con la composición de las plantas, ingreso de la materia orgánica (residuos), el clima (temperatura y humedad), pr...
Nitrogen (N), being the most critical and essential nutrient for plant growth, largely determines the productivity in both extensive- and intensive- grassland systems. Nitrification and denitrification processes in the soil are the primary drivers generating reactive-N: NO3-, N2O, and NO, and is ...
Forage-based livestock production plays a key role in national and regional economies, for food security and poverty alleviation. Livestock production is also considered as a major contributor to agricultural GHG emissions, however. While demand for livestock products is predicted to continue to ...
The presentation addresses the influence that cultivation of forage can have on the accumulation of carbon in pasture soils. Presentation given by Jacobo Arango at COP 23 in Bonn, Germany on 12 November 2017.
Poor drainage is found on about 11.3% of agricultural land in Latin America where physiography promotes flooding, high groundwater tables, or stagnant surface water (waterlogging). Waterlogging drastically reduces oxygen diffusion into the soil causing hypoxia which is the main limitation that re...
The Amazon Basin is so diverse that one could say many Amazons exist, not just one. Indeed, its diversity is considered unique in the world. Although the Basin occupies 7% of the planet’s land, it carries 25% of the world’s terrestrial biodiversity. The region is so vast, it represents one-third ...
