RESUMEN La erosión en cárcavas, clásicas o efímeras, es la manifestación más extrema del proceso de erosión hí-drica. El carcavamiento altera y fragmenta significativamente el paisaje y aumenta los costos productivos. Este estudio evalúa la dinámica del carcavamiento en la cuenca del arroyo del Tala (San Pedro, Bs. As.), representativa de la pampa...
Nitrous oxide (N2 O) emission estimation derived from the application of synthetic fertilizers using default emission factors and in a homogeneous way throughout the country for the Inventories of Greenhouse Gases of Argentina do not reflect local productive characteristics and the regional differences. The objectives of this study were a) to disag...
According to the available guidelines, good practices for calculating nitrous oxide (N 2 O) emission factors (EFs) for livestock excreta and manure application include that sampling duration should be of at least one year after the nitrogen (N) application or deposition. However, the available experimental data suggest that in many cases most emiss...
La erosión en cárcavas es un fenómeno irreversible que puede afectar el ciclo hidrológico de las microcuencas, incrementando la conectividad del paisaje y el movimiento de agua y sedimentos. En la Argentina, si bien se publicaron algunos trabajos al respecto en regiones áridas o semiáridas, este tipo de erosión no ha sido suficientemente estudiado....
Introducción:
el diagnóstico de fertilidad mejora al incluir el aporte de nitrógeno (N) mineralizable de la fracción orgánica del suelo. El objetivo fue estimar el potencial de mineralizar N de suelos representativos de la región Huánuco.
Materiales y métodos:
se estudió el efecto del manejo sobre los contenidos y distribución superficial de la ma...
The use of cover crops, combined with low N fertilization and no-tillage, reduces the environmental impacts of agriculture. Legume cover crops provide N to the agroecosystem and allow N fertilization to be reduced without losing productivity, but may also increase nitrous oxide (N 2 O) emissions. Our main objective was to evaluate the impact of usi...
Riparian buffer strips can have a significant role in reducing nitrogen (N) transfers from agricultural land to freshwater primarily via denitrification and plant uptake processes, but an unintended trade-off can be elevated nitrous oxide (N2O) production rates. Against this context, our replicated bounded plot scale study investigated N2O emission...
About half of the applied nitrogen (N) is not consumed by crops, causing environmental and economic costs. This N can be lost as ammonia (NH3) volatilization, nitrous oxide (N2O) emission or leaching, among others. This work aimed to compare the amount of gaseous N losses using three different fertilizers on two consecutive experiments: one summer...
One third of Argentina is affected by water erosion and, to a lesser extent, by wind erosion. Recently the area and rate of these processes grew significantly. The main reasons are overgrazing, deforestation, land use change and inadequate cropping practices. We analyzed the effect of grasslands conversion into croplands, particularly its impact on...
La erosión hídrica es el principal proceso de degradación de las tierras a nivel mundial y afecta a más del 30% de las tierras de la Pampa Ondulada argentina. El presente trabajo tuvo como objetivo determinar y analizarla erosividad de las lluvias (R) para el partido de San Pedro (Bs As, Argentina) para el período (2001-2013). El índice de erosivid...
Water erosion is the main land degradation process over the world and affects more than 30% of the lands in the Rolling Pampa region of Argentina. The objective of this study was to analyse rainfall erosivity for the San Pedro County during 2001-2013. The individual erosivity index EI³⁰ was significantly correlated with the daily rainfall events (y...
A nivel mundial, los sistemas agrícolas se enfrentan a muchos desafíos. Uno de ellos es aumentar la producción de alimentos reduciendo los efectos nocivos sobre el medio ambiente mitigando el cambio climático a través de prácticas sustentables. Entre las opciones disponibles, el uso de mezclas de leguminosas y gramíneas como cultivo de cobertura (C...
