13. Reforestation of a Degraded Area with Eucalyptus and Sesbania: Microbial Activity and Chemical Soil Properties
ABSTRACT Mining activities generally affect soil quality, degrading it and creating the need for consistent environmental recovery efforts. This study evaluates the influence of monospecific and mixed stands of Sesbania virgata (S) and Eucalyptus camaldulensis (E) on the chemical properties and microbial activity of the soil in a degraded area by clay extrac

14. Biological Soil Properties in Integrated Crop-Livestock-Forest Systems
ABSTRACT Currently, agricultural productivity and sustainable development are the desired bases for the creation of production systems. Farming for greater production and the efficient use of soil resources are at the core of modern systems. However, the way in which agricultural management and practices can change soil quality has become increasingly import

15. Differential response of microbial respiration to supplied nitrogen forms in 3 contrasting alpine meadow soils on the Tibetan Plateau
ABSTRACT An incubation experiment was conducted to examine the effects of nitrogen (N) applications in different forms (NH4NO3, NH4Cl, and KNO3) on microbial respiration considering 3 different alpine meadow soils (C poor soil, pH = 8.1, 1.6% C; C moderate soil, pH = 6.0, 5.0% C; C rich soil, pH = 7.1, 7.4% C) in the Tibetan Plateau. The addition of NH4NO3 a

16. Microbiological Attributes of Soil Under Spontaneous Restoration
ABSTRACT The aim of this study was to evaluate the effect of vegetation on soil microbial activity during spontaneous restoration and the effect of remaining eucalypts on the restoration stage of reserve ranges installed in eucalypt plantations. The studied areas were in the following stages: initial restoration stage with and without remaining eucalypts; ad

17. Biological Properties and Organic Matter Dynamics of Soil in Pasture and Natural Regeneration Areas in the Atlantic Forest Biome
ABSTRACT The removal of original vegetation for crops and pasture production and then followed by natural regeneration is a standard practice in the Atlantic Forest, which has produced patches with different degrees of degradation and regeneration across the landscape. The aim of this study was to evaluate the effects of replacement of native forest by pastu

18. Comparing how land use change impacts soil microbial catabolic respiration in Southwestern Amazon
Abstract Land use changes strongly impact soil functions, particularly microbial biomass diversity and activity. We hypothesized that the catabolic respiration response of the microbial biomass would differ depending on land use and that these differences would be consistent at the landscape scale. In the present study, we analyzed the catabolic response pro

19. ATRIBUTOS MICROBIOLÓGICOS DO SOLO EM SISTEMA DE INTEGRAÇÃO LAVOURA-PECUÁRIA
O sistema de integração lavoura-pecuária (ILP) tem se evidenciado como alternativa viável para a recuperação e manutenção das características do solo. Este estudo foi desenvolvido em um experimento de ILP conduzido pelo Instituto Agronômico do Paraná no município de Xambrê, PR, com diferentes intensidades de pastejo. O objetivo deste trabalho fo

20. Humic fractions of forest, pasture and maize crop soils resulting from microbial activity
Humic substances result from the degradation of biopolymers of organic residues in the soil due to microbial activity. The objective of this study was to evaluate the influence of three different ecosystems: forest, pasture and maize crop on the formation of soil humic substances relating to their biological and chemical attributes. Microbial biomass carbon

21. Agroforestry systems, nutrients in litter and microbial activity in soils cultivated with coffee at high altitude
Agroforestry systems are an alternative option for sustainable production management. These systems contain trees that absorb nutrients from deeper layers of the soil and leaf litter that help improve the soil quality of the rough terrain in high altitude areas, which are areas extremely susceptible to environmental degradation. The aim of this study was to

22. Soil health: looking for suitable indicators. What should be considered to assess the effects of use and management on soil health?
Soil Health refers to the ecological equilibrium and the functionality of a soil and its capacity to maintain a well balanced ecosystem with high biodiversity above and below surface, and productivity. To understand and use soil health as a tool for sustainability, physical, chemical, and biological properties must be employed to verify which respond to the

23. Atividade microbiana e propriedades bioquímicas do solo sob a adição de composto orgânico e palha de café / Microbial activity and biochemical properties of the soil after the addition of organic compost and coffee trash
Na agricultura moderna e com a adoção de práticas de manejo mais sustentáveis, o uso de resíduos orgânicos na agricultura tem sido visto como uma importante escolha, principalmente por se tratar de materiais recicláveis no solo. O trabalho foi conduzido com a adição de composto orgânico enriquecido com fosfato natural (COM), nas quantidades de 0, 1

24. Application of cassava starch and carnauba wax-based edible coatings in minimally processed apples / Aplicação de coberturas comestíveis à base de fécula de mandioca e cera de carnaúba em maçãs minimamente processadas
This study aimed at formulating a cassava starch, carnauba wax and stearic acid or palmitic acid - based edible coating, and evaluating their properties and their effects when applied to minimally processed apples. In a first step, Plackett-Burman designs were performed for the following variables selection of coating formulations: cassava starch concentrati
