1. Sensitivity analysis of the AquaCrop model for wheat crop in Campos Gerais region, Paraná
ABSTRACT The use of crop modeling can be useful to understand the interactions between the soil-plant-atmosphere system. The objective of this study was to evaluate sensitivity analysis of the AquaCrop model parameters for wheat crop in the Campos Gerais Region. The varietie tested was TBIO Sinuelo in Castro, Ponta Grossa and Itaberá cities. The analyzed pa

2. Comparação entre variáveis microclimáticas de local aberto e florestal em um bioma da Mata Atlântica, sul do Brasil
Resumo Na região subtropical do Brasil, o ambiente é naturalmente caracterizado pelo clima quente e úmido. Essas condições são fatores preponderantes para a ocorrência da formação florestal na região, o bioma Mata Atlântica. Associa-se que qualquer condição diferente daquela que não seja natural, pode receber de forma diferenciada a condição

3. Methane emission induced by short-chain organic acids in lowland soil
ABSTRACT Methane (CH4) is the second major greenhouse gas after CO2, exerting a significant influence on the climate and the chemistry of the atmosphere. In lowland soil, acetate and H2/CO2 are the most important precursors of CH4 and formed from organic matter fermentation in an anaerobic environment, giving rise to short-chain organic acids (ethanoic, prop

4. Fertilization and Irrigation Affect Soil Carbon under Eucalyptus Plantation in the Cerrado
ABSTRACT This study aimed: i) to evaluate the influence of fertilization and irrigation management on eucalyptus plantations for soil carbon (C) dynamics; ii) to evaluate the impact of fertilization and irrigation management on eucalyptus plantations in the C allocation in depth compared to the Cerrado biome. This study was carried out in an eucalyptus plant

5. Response of bell pepper to water replacement levels and irrigation times
RESUMO Diferentes horários de irrigação resultam em diferentes taxas de transpiração, devido à disponibilidade de água e sua interação com a demanda evapotranspirativa. O déficit de pressão de vapor é um indicador preciso da capacidade evaporativa da atmosfera e pode afetar as plantas, devido ao movimento da água no sistema contínuo solo-planta

6. Automation of lettuce seedlings irrigation with sensors deployed in the substrate or at the atmosphere
ABSTRACT: Seedling production is an important step in the lettuce production system. However, there is a tendency to apply excessive irrigation at this stage. The aim of this study was to test the use of the Simplified Irrigation Controller (SIC) under two conditions: first, with the sensor installed in the substrate (measuring the soil water tension) and se

7. Development, calibration and validation of weighing lysimeters for measurement of evapotranspiration of crops
RESUMO O processo de evapotranspiração é fundamental em estudos de balanço e demanda hídrica de culturas e sua determinação pode ser realizada por diversos métodos. Um método muito utilizado, apesar de seu custo elevado de instalação são os lisímetros de pesagem, que consistem em uma caixa sobre uma balança, conectados a uma célula de carga qu

8. Carbon in Physical Fractions and Organic Matter Chemical Composition of an Acrisol after Amazon Forest Burning and Conversion into Pasture
The aim of this study was to investigate impacts of Amazon Forest (AF) fire and conversion to pasture on carbon accumulation in particle size fractions and organic matter (OM) composition of an Acrisol. Soil samples were collected (0.00-2.00 m depth) in three sites: native AF (NAF); AF under natural regeneration for two years after burning (BAF); 23-years ol

9. Soil carbon stock and humification in pastures under different levels of intensification in Brazil
ABSTRACT: Intensive management of tropical pastures has shown potential for greenhouse gas (GHG) mitigation due to high forage production and C accumulation in the soil. This study aimed to evaluate different pasture management options in relation to their effect on soil C stocks and soil organic matter (SOM) humification. Pastures in four beef cattle produc

10. Hourly, Daily, and Monthly Soil Temperature Fluctuations in a Drought Tolerant Crop
ABSTRACT Soil temperature is a physical property of great agricultural importance in the soil-plant relationship and in energy exchange with the atmosphere. This study was conducted in a degraded Cambissolo Háplico Ta Eutrófíco (Cambisol; Inceptisol) in the Irecê Identity Territory, Bahia, Brazil, aiming to evaluate the hourly, daily, and monthly fluctua

11. Influence of the Transport of Sea Spray on the Salinization of the Semiarid Region Waters (Bahia, Brazil)
The sea spray can be transported to long distances, reaching the semiarid regions. In this work, the rainwater and the atmospheric particulate matter were characterized by investigating the presence of sea spray in the atmosphere of the semiarid region of Bahia, Brazil, aiming to study the influence of its transport on the salinization of the waters of the r

12. MANEJO DE RESIDUOS DE Eucalyptus grandis Hill ex Maiden EN SITIOS CONTRASTANTES
ABSTRACT In northeastern Argentina, very little is known about the impact of various techniques of management of residues from forest harvesting on soil properties. We carried out this study in two sites in Entre Ríos Province (Argentina): post-harvest of Eucalyptus grandis Hill ex Maiden stands in an Aquic Hapludert (S1) and in a Fluventic Hapludoll (S2).
