Assessing how accumulated precipitation and long dry sequences impact the soil water storage
(John Wiley & Sons Ltd, 2017-04)
Precipitation or no precipitation persistent over time often became extreme weather conditions with greater regional economic impact. The temporal and spatial variability of these variables, together with the evapotranspiration, ...
El Niño–Southern Oscillation incidence over long dry sequences and their impact on soil water storage in Argentina
(John Wiley & Sons Ltd, 2019-03)
The deficit of daily precipitation, persistent over time (long dry sequences [LDS]), causes economic losses in the east–northeast of Argentina where agriculture production is the main economic activity. For this reason, ...

How have daily climate extremes changed in the recent past over northeastern Argentina?
(Elsevier Science, 2018-09)
Changes in climate extremes affect socioeconomics and natural systems in northeastern Argentina (NEA) and may increase its vulnerability leading to unprecedented disasters. This study investigates the long-term changes and ...
Improving soil fertility with lime and phosphogypsum enhances soybean yield and physiological characteristics
(2022-04-01)
In tropical no-till systems, applying lime (L) and phosphogypsum (PG) on the soil surface may be a potential strategy for reducing soil acidification and improving soybean root growth, thereby enhancing plant nutrition and ...
Long-term liming improves soil fertility and soybean root growth, reflecting improvements in leaf gas exchange and grain yield
(2021-08-01)
Soil acidity is one of the major drivers of yield-limited crop productivity, particularly when combined with dry spells during crop development. Liming is a widely used strategy for alleviating the negative effects of soil ...
Long spelling periods are required for pasture to become free of contamination by infective larvae of Haemonchus contortus in a humid subtropical climate of São Paulo state, Brazil
(2020-03-01)
The objective of this trial was to evaluate the period of spelling necessary for a pasture to become free of contamination by infective larvae of gastrointestinal nematodes (GIN) of sheep, in different seasons of the year, ...
Potential changes in extremes and links with the Southern Annular Mode as simulated by a multi-model ensemble
(Springer, 2010-02)
We assess the likely changes in climate extremes under enhanced greenhouse gases over the southern extratropics, with emphasis in southern South America and sub-Antarctic seas, through the analysis of extreme indices ...
