25. Developing a Soil Physical Quality Index (SPQi) for lowlands under different deployment times of no-tillage
ABSTRACT: Soil physical quality in lowlands from the Pampa biome under no-tillage (NT) plays an important role; therefore, this study aimed to establish a soil physical quality index (SPQi) from a minimum data set to detect the effects of different deployment times of NT in an Albaqualf. The comparison of areas with one (NT1), three (NT3), five (NT5) and sev

26. Water retention and penetration resistance equations for the least limiting water range
ABSTRACT: The least limiting water range is a soil physical quality indicator, which is useful to predict the optimum water range for plant growth in a given soil and to study the effects of soil use and management over this optimum water range by integrating the effects of available water, penetration resistance and air filled porosity. This study tested si

27. Advances in the spread of vegetative blueberry
Resumo A falta de método eficiente de propagação em algumas cultivares dificulta a expansão da cultura do mirtileiro. No Brasil ainda não se produz muda com qualidade e quantidades necessárias para alavancar o setor. A clonagem do material selecionado através de minipropagação e micropropagação é uma alternativa para aumentar a capacidade de mul

28. MANUFACTURE OF SOIL-CEMENT BRICKS WITH THE ADDITION OF SUGARCANE BAGASSE ASH
ABSTRACT The objective of this study is to evaluate the effect of sugarcane bagasse ash on the compressive strength and water absorption index of soil-cement bricks. The ash was sieved without chemical and/or physical treatment to reflect the use of this material in real manufacturing processes. The addition of natural ash decreased the quality of the bricks

29. Morphological diversity of springtails (Hexapoda: Collembola) as soil quality bioindicators in land use systems
Resumo: O objetivo deste trabalho foi avaliar a qualidade do solo de florestas nativas, reflorestamento de eucalipto, pastagem, sistemas de integração lavoura-pecuária e plantio direto, correlacionando a diversidade morfológica de colêmbolos com propriedades físicas e químicas do solo. Amostras de colêmbolos foram coletadas de solos do planalto sul d

30. 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

31. Mapping Soil Cation Exchange Capacity in a Semiarid Region through Predictive Models and Covariates from Remote Sensing Data
ABSTRACT: Planning sustainable use of land resources requires reliable information about spatial distribution of soil physical and chemical properties related to environmental processes and ecosystemic functions. In this context, cation exchange capacity (CEC) is a fundamental soil quality indicator; however, it takes money and time to obtain this data. Alth

32. Satellite Spectral Data on the Quantification of Soil Particle Size from Different Geographic Regions
ABSTRACT: The study of soils, including their physical and chemical properties, is essential for agricultural management. Soil quality must be maintained to ensure sustainable production of food and conservation of natural resources. In this context, soil mapping is important to provide spatial information, which can be performed using remote sensing (RS) te

33. Long-Term Effect of Soil Use and Management on Organic Carbon and Aggregate Stability
ABSTRACT: The conversion of native grassland into farmland causes changes in the soil. Tillage has profound effects on soil organic matter. The intensification of soil tillage decreases soil quality by reducing aggregate stability. Soil aggregate stability and soil organic matter are key indicators for soil quality and environmental sustainability in agro-ec

34. Morphological Diversity of Springtails in Land Use Systems
ABSTRACT: Springtails (Collembola) are soil organisms with wide morphological diversity and are sensitive to alterations in the soil, regardless of whether they are human-caused or not. The aim of this study was to evaluate the influence of land use on the morphological diversity of springtails and verify their relationships with soil physical, chemical, and

35. Physical Quality of a Typic Hapludult Soil Under Forest Leguminous Trees and Pasture
ABSTRACT Revegetation with leguminous trees has been used to recover degraded areas. This study aimed to evaluate the physical quality of a Typic Hapludult soil under secondary forest, pasture and three leguminous tree species: Acacia (Acacia auriculiformis), Sabia (Mimosa caesalpiniaefolia) and Inga (Inga spp. ), in Conceição de Macabú County, Rio de Ja

36. Soil physical indicators of management systems in traditional agricultural areas under manure application
ABSTRACT Studies of the successive application of manure as fertilizer and its combined effect with long-term soil management systems are important to the identification of the interdependence of physical attributes. The aim of this study was to evaluate changes in the physical properties of a Rhodic Kandiudox under management systems employing successive ap
