25. Decomposition and Nutrient Release of Cover Crops in Mango Cultivation in Brazilian Semi-Arid Region
ABSTRACT Knowledge of the decomposition dynamics of aboveground phytomass and its release of nutrients in mixtures of cover crops as well as the impact on the soil tillage system is fundamental for the sustainable management of agroecosystems. This work aimed to evaluate whether soil tillage and the choice of cover crops cultivated in the interrows can be te

26. SOIL PHYSICAL ATTRIBUTES AND PRODUCTION COMPONENTS OF SUGARCANE CULTIVARS IN CONSERVATIONIST TILLAGE SYSTEMS
ABSTRACT Machine traffic and conventional tillage can cause structural degradation of the soil, affecting the physical attributes and, consequently, the production and longevity of the sugarcane field. The objective of this study was to evaluate the production components of sugarcane cultivars (RB965902, RB985476, RB966928, RB855156, RB975201, RB975242, RB03

28. Soil mesofauna in consolidated land use systems: how management affects soil and litter invertebrates
ABSTRACT: Soil mesofauna consists of small invertebrates that live in the soil or litter and are sensitive to climatic conditions, management systems, plant cover and physical or chemical soil attributes. These organisms are active in the cycling of nutrients, since they fragment the organic matter hereby accelerating microbial decomposition. The aim of this

29. Response of the TDR sensor to moisture under different types of management of a typical Latosol in the Cerrado
RESUMO A técnica de Reflectometria no Domínio do Tempo (TDR) tem se destacado na avaliação da umidade do solo, por ser um método instantâneo, não destrutivo, preciso e pouco dependente dos fatores ambientais. Porém, pesquisadores têm enfatizado a necessidade de calibração específica e contínua para cada condição de manejo do solo. Portanto, ob

30. TRACTIVE DEMAND, SOIL MOBILIZATION PARAMETERS, AND CORN YIELD IN COMPACTED OXISOL
ABSTRACT Direct seeding systems are characterized by soil disturbance only occurring in the sowing line and the maintenance of the remaining area is achieved by covering with crop residues. Without total area soil mobilization as recommended by the no-tillage system, associated with the increase in the degree of soil compaction caused by the traffic of agric

31. Diversity of soil spiders in land use and management systems in Santa Catarina, Brazil
Resumo: A capacidade de dispersão das aranhas em áreas contíguas (Arachnida, Araneae) está ligada diretamente às condições de manejo do solo. Objetivou-se com o presente trabalho estudar o efeito do sistema de uso do solo (SUS) sobre a abundância e diversidade das famílias de aranhas edáficas, bem como a relação dessas com os atributos físicos e

32. 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

33. 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

34. Root and Shoot Contribution to Carbon and Nitrogen Inputs in the Topsoil Layer in No-Tillage Crop Systems under Subtropical Conditions
ABSTRACT Recycling of carbon (C) and nitrogen (N) from plants into soils is decisive for maintaining soil organic matter and soil fertility. Therefore, we quantified plant biomass and C and N in the shoots and roots from the topsoil layer for a wide range of annual crops grown under subtropical conditions. We grew 26 species, 13 main crops, and 13 cover crop

35. 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

36. Inceptisol Physicochemical Attributes in the Caatinga Biome Agroforestry Systems
ABSTRACT We evaluated two areas of sustainable management within the Caatinga and one area of conventional agricultural cultivation to compare their physicochemical attributes with those of native forest. The management strategies were as follows: (1) thinning of savanna; (2) thinning of strips; (3) conventional tillage with plowing and harrowing; and (4) n
