14. Potential of aqueous extracts of basidiomycetes to control root-knot nematodes on lettuce
RESUMO Os nematoides das galhas (Meloidogyne incognita) estão entre as principais pragas da alface em função da elevada suscetibilidade da cultura, indisponibilidade de nematicidas e carência de cultivares resistentes. Foi objetivo deste trabalho, avaliar o potencial de extratos aquosos de dez diferentes basidiomicetos no controle de nematoides das galha

15. Evaluation of common bean genotypes for drought tolerance
ABSTRACT The aim of this study was to evaluate twelve genotypes of common bean for intermittent drought stress and for root growth angle. The water deficit experiments were conducted in 2015 and 2016in a randomized block experimental design with split plots and three replications. Two treatments were applied: an irrigated treatment and a water deficit treatm

16. Soil Water Retention Curve as Affected by Sample Height
ABSTRACT: The soil water retention curve is one of the main instruments to assess the soil physical quality and to improve soil management. Traditionally, the equipment most used in the laboratory to determine the retention curve has been Haines funnels and Richards chambers. An important factor to which little attention has been given in the use of these eq

17. Determinación del consumo de agua potable durante la construcción de viviendas en una zona semi desértica de Chile
ABSTRACT In recent years, water scarcity in northern Chile has increased markedly, leading to an over exploitation of groundwater aquifers. In the construction sector, water is used in large quantities throughout the different activities of the construction projects, this fact makes essential to quantify the water consumption in order to know the real demand

18. An Alert Regarding a Common Misinterpretation of the Van Genuchten α Parameter
ABSTRACT Among the equations available to describe the relation between matric potential and soil water content, the soil water retention function, the most commonly used is the equation proposed by Van Genuchten in his 1980 landmark paper. In soil physics literature, especially in Brazil, several authors relate the inverse of the Van Genuchten parameter α

19. Water Erosion in Oxisols under Coffee Cultivation
ABSTRACT Water erosion is one of the main environmental impacts of land use. When soil and water losses occur, nutrients essential for the growth and maintenance of plants are removed, with harmful outcomes on the sustainability of agriculture and the environment. In addition, they lead to other deleterious effects, such as sedimentation and eutrophication o

20. Multivariate Analysis of Erosivity Indices and Rainfall Physical Characteristics Associated with Rainfall Patterns in Rio de Janeiro
ABSTRACT The identification of areas with greater erosive potential is important for planning soil and water conservation. The objective of this study was to evaluate the physical characteristics of rainfall events in the state of Rio de Janeiro, Brazil, and their interactions with rainfall patterns through multivariate statistical analysis. Rainfall depth,

21. Natural environmental water sources in endemic regions of northeastern Brazil are potential reservoirs of viable Mycobacterium leprae
BACKGROUND The detection of live Mycobacterium leprae in soil and animals other than humans suggests that the environment plays a role in the transmission of leprosy. OBJECTIVE The objective of this study was to investigate the presence of viable M. leprae in natural water sources used by the local population in five municipalities in the state of Ceará,

22. Water Erosion in a Long-Term Soil Management Experiment with a Humic Cambisol
ABSTRACT Water erosion, the main factor in soil degradation, is strongly influenced by soil cover and management. The objective of this study was to determine soil and water losses under natural rainfall conditions from 1993 to 2012 in the southern Santa Catarina Plateau, Brazil, in 3.5 × 22.1 m plots with crops in rotation to study the following management

23. Soil Compressibility under Irrigated Perennial and Annual Crops in a Semi-Arid Environment
ABSTRACT In irrigated soils, a continuous state of high moisture reduces resistance of the soil to applied external forces, favouring compaction. The aim of this study was to evaluate the susceptibility to compaction of developed calcareous soils in irrigated annual and perennial cropping systems of the Apodi Plateau, located in the Brazilian semi-arid regio

24. STATISTICAL CONTROL OF PROCESSES APLIED FOR PEANUT MECHANICAL DIGGING IN SOIL TEXTURAL CLASSES
ABSTRACT The digging of peanut, which has the pod production in the subsurface, is directly affected by soil conditions, physical or environmental characteristics, at the time of operation and may be the cause of unwanted losses. Therefore, the quality of the operation is very important for minimizing these losses. Thus, this study aimed to evaluate the qual
