Abstract. In this paper, we present and analyze a novel global database of soil infiltration measurements, the Soil Water Infiltration Global (SWIG) database. total, 5023 curves were collected across all continents in SWIG These data either provided quality checked by scientists who performed experiments or they digitized from published articles. Data 54 different countries included with major contributions Iran, China, USA. addition to its extensive geographical coverage, cover research...
ABSTRACT Although the hydrological importance of water infiltration into soil and surface runoff is well known, manual measurement these processes, especially at plot hillslope scales, laborious requires a trained team. This study aimed to develop prototypes with tipping bucket principle for automatic monitoring scale (14.5 × 3 m). In total, 18 were built installed in an experiment different covers. Aspects construction, calibration, operation maintenance reported this study. Prototypes...
O objetivo do estudo foi avaliar a eficiência agronômica da inoculação de sementes trigo e milho com Azospirillum brasilense, em associação à adubação nitrogenada. Sete tratamentos foram avaliados, associando aplicação nitrogênio (N), sob delineamento blocos ao acaso, 4 repetições, totalizando 28 unidades experimentais área individual 27,2 m2. Na cultura avaliado o número perfilhos por planta, espigas metro quadrado, grãos espiga, rendimento massa seca grãos, mil peso hectolitro. No...
The normalized dispersion index (NDI) and the b/a are commonly used to express stability of aggregates measured by ultrasound. However, few studies have critical energy (CE) extracted from modeling explain effects soil use management on aggregation. objective this study was evaluate influence cover CE level required for a Typic Hapludalf. Soil samples collected 0.0-0.05 m depth were evaluated in five different managements with plants: perennial soybean (PS), peanuts (P), spontaneous...
ABSTRACT In hydrological modeling and for the development of projects related to soil water conservation civil engineering, determination infiltration variables into plays a key role. However, measuring with manual infiltrometers is work-intensive requires several people, which casts doubts on consistency process description. Our objective was develop automated compact systems data acquisition by double-concentric-ring Cornell infiltrometers. The are based air differential pressure sensors...
Abstract. In this paper, we present and analyze a global database of soil infiltration measurements, the Soil Water Infiltration Global (SWIG) database, for first time. total, 5023 curves were collected across all continents in SWIG database. These data either provided quality checked by scientists who performed experiments or they digitized from published articles. Data 54 different countries included with major contributions Iran, China, USA. addition to its spatial coverage, cover time...
Integrated crop-livestock systems are being increasingly used to intensify food production and make it more sustainable. On the other hand, most studies have focused on extensive systems. This paper analyzed effects of different managements soil plants in an intensive integrated system for milk production. An experiment management was installed southern Brazil, Rio Grande do Sul, a Latossolo Vermelho (Oxisol), 2015 evaluate: rotational grazing dairy cows winter; winter followed by chiseling;...
Sonificação tem sido uma ferramenta útil para mensurar a energia necessária promover dispersão dos agregados. Este trabalho objetivou avaliar o efeito de plantas cobertura na macroagregação um ARGISSOLO VERMELHO Distrófico arênico usando ultrassônica. Agregados (8-4,76 mm) foram coletados da camada 0,0-0,05 m profundidade em diferentes manejos com cobertura: VE - vegetação espontânea, AVNA aveia preta + nabo forrageiro, AVER ervilhaca peluda, GR Grama Pensacola, AF amendoim forrageiro. Solo...
Ultrasonic-based techniques allow the prediction of energy required to break aggregate and have been more commonly used measure stability aggregates. Although they result in same applied energy, certain combinations time power might correspond different intensities cavitation. Consequently, responses aggregation indexes can be obtained with configurations ultrasound techniques. Thus, this work was carried out evaluate effects cavitation intensity distribution aggregates a Paleudalf under...
