The Argentine Pampas (figure 1) is located in the south cone of South America (31° to 39° S and 58° 65° W). region extends along 55 60 million ha (135 148 ac) was originally covered with temperate grasslands. shows several similarities as well differences their equivalent grassland North America. In a simplified picture, climate humid east subhumid/semiarid west. Rainfall varies from 1,200 mm y−1 (47 yr−1) 500 (20 Fall spring/summer are rainier seasons but there considerable variability...
ABSTRACT Maize production is affected by water and nitrogen (N) deficit either separately or joined, but this fact not completely defined. The aim was to evaluate the fate of N in maize fertilized subjected stress controlled conditions. A greenhouse experiment carried out at University Buenos Aires campus. design a 2 × factorial with four replications. factors were N: 70 140 kg ha−1 as labeled urea (15N), water: 100% 50% potential evapotranspiration. harvest aerial root biomass R1 stage....
The goal of nutrient management is to optimize nutrient's advantages, and minimize their disadvantages. Nutrient use efficiency has consider the effect link between a field's soil, crop, weather, hydrology, along with practices being used on property, such as irrigation, fertilizer, manure management. This tall order. In addition, manager's decisions have potential increase one element, while simultaneously reducing second nutrient, increasing its losses (Delgado Lemunyon, 2006). Luckily,...
Abstract The knowledge of nitrogen (N) losses in direct‐drilling agrosystems is essential to develop strategies increase fertilizer efficiency and minimize environmental damage. objectives were i) quantify the magnitude N volatilization leaching simultaneously as affected by different urea fertilization rates ii) evaluate capacity these specific plant–soil systems act a buffer prevent nitrate leaching. Two experiments conducted during 2001/02 2002/03 growing seasons Alberti, Argentina. crop...
Cover crops are well known for their positive effects on erosion processes, soil organic matter, physical properties, weed populations and nitrate (NO<sub>3</sub>) leaching. In this work, we evaluated the fate of nitrogen (N) from fertilizer in maize (<i>Zea mays</i> L.) then ryegrass (<i>Lolium multiflorum</i>) as cover crop, conditions Argentine Pampas. To end, a field experiment was carried out at School Agriculture, University Buenos Aires, Argentina (34°36′ S, 58°29′ W). The design...
La cantidad y calidad de carbono del mantillo forestal que ingresa al suelo depende varios factores, entre ellos la especie implantada, el manejo, edad plantación, las condiciones climáticas textura suelo. Los objetivos este trabajo fueron i) cuantificar contenido orgánico lábil en suelos con plantaciones Eucalyptus grandis (Eucalyptus grandis) región mesopotámica evaluar su relación tipo mantillo; e ii) identificar aquellos factores edáficos ambientales influyen variación. Se trabajó sobre...
Nitrous oxide (N2O) is a greenhouse gas that contributes substantially to global climate change. The N2O soil emissions have large uncertainty because of its low atmospheric concentration levels and enormous spatial temporal variability, which hinders correct field measurement. For this reason, there are many papers focused on improving the measurements in field, focus different parts measurement process. However, no studies determining appropriate method, terms [...]
