| Abstract: The choice of areas for nature conservation involves the attempt to maximize the benefits, whether by carrying out an economic activity or by the provision of Ecosystem Services. Studies are needed to improve the understanding of the effect of the extent and position along the watershed of restored areas on soil and water conservation. This study aimed to understand how different restoration strategies might reflect in soil conservation and sediment retention. Using InVEST tool, sediment transport was simulated in a small 12 km2 watershed (Posses River, in Southeast Brazil), where one of first Brazilian Payment for Ecosystem Services (PES) projects is being carried out, comparing different hypothetical restoration strategies. With 25% of... |

| Few studies have been carried out on aboveground (or belowground) and soil/substrate C accumulation in severely degraded areas, such as mined areas. The present study was developed in order to find a recovery strategy for a mined area and characterize its potential for C sequestration by planting two nitrogen-fixing Brazilian tree species (Mimosa caesalpiniifolia Benth and M. bimucronata (DC.) O. Kuntze). Sewage sludge was included in the experimental design. An experiment under randomized block condition and 2 x 5 factorial design with four replications were defined and carried out, in Rio de Janeiro State, Brazil. The treatments consisted of a combination of both tree species and five sewage sludge doses (0, 2.85; 5.70; 11.40 and 22.80 Mg ha-1). M.... |

| Shooting range activities risk contaminating the soil, posing potential risks to human health, the local biota, and water sources. Considering that soil organisms are the first to be affected by contamination, this study aimed to evaluate the initial growth of the leguminous tree Albizia polycephala and its association with microbes in soil taken from this area. The collected soil was placed in 60-ml tubes with legume seeds and stored in a greenhouse for 60 days. The differences in the legumes? growth were not related to the physical and chemical properties of the soil, norto its metal content, but rather to mycorrhizal colonization and nodulation, which were shown to be effective in creating favorable conditions. This indicates that the site under study... |

| Resumo: Considerando que a intensificação do manejo das pastagens é o caminho para o desenvolvimento da atividade pecuária no Brasil e que essa atividade se baseia em práticas de fertilização, principalmente nitrogenada, torna-se importante conhecer os impactos dessa prática nas emissões de óxido nitroso (N2O). Diante disto, o objetivo com este trabalho foi avaliar a emissão de N2O proveniente de pastagens de Urochloa brizantha L. adubada com nitrato de amônio. O experimento foi conduzido de novembro de 2019 a fevereiro de 2020, no Instituto de Zootecnia, Nova Odessa-SP. A pastagem é formada com Urochloa brizantha cv. Marandu e o sistema de pastejo é com lotação variável, em função da disponibilidade de forragem. Para o monitoramento dos fluxos de N2O,... |

| Soils in urban areas often present characteristics that might submit these environments to erosion processes. Applying municipal solid wastes (MSW) composts to soils have been suggested as a means to improve physical and chemical properties. A field experiment with a completely randomized design was conducted in a Typic Argiudoll from a degraded area in Buenos Aires City. The objective was to evaluate the effect of MSW compost application on soil properties, residue decomposition and Poa (Poa pratensis L.) reestablishment. At the beginning of the trial, compost was prepared and applied in a bare soil on 0.25 m² square plots afterwards litterbags were incorporated and Poa was sown. Compost amounts were: 0 (control); 2 (low); 4 (medium) and 7 kg m-2 (high)... |

| Purpose: Sugarcane vinasse is generated in large amounts and can be utilized to improve soil attributes, especially in areas degraded by burns. The aim of the present study was to evaluate the effects of sugarcane vinasse on physico-chemical attributes of a Cambisol managed via annual burns. Methods: Soil samples were collected from an annually burned area under pasture and used in an experiment in pots to evaluate the effects of dosages of vinasse (0, 18.8, 37.5, 56.3, 75.0, 112.5, and 150.0 m3 ha-1) on water-dispersible clay, pHH2O , organic matter, K+, Ca2+ + Mg2+, and K+/( Ca2+ + Mg2+). Results: The results showed that vinasse application reduces water-dispersible clay, does not alter pHH2O , and increases organic matter, K+, Ca2+ + Mg2+, and K+/(Ca2+... |

| A produção pecuária brasileira, baseada no extrativismo e na baixa sustentabilidade, causa produção limitada, viabilidade econômica e degradação do solo. Sistemas integrados são alternativas viáveis, sustentáveis e aplicadas à realidade dos produtores. O objetivo do presente trabalho foi medir a qualidade física, biológica e química do solo e avaliar parâmetros biofísicos por sensoriamento remoto. O experimento foi conduzido em Rio Verde - Goiás, com sete tratamentos: pastagem degradada, pastagem degradada com adubação, reforma convencional de pastagem, integração de plantio florestal (com árvores frutíferas e olivais), integração pecuária- floresta com pastagem, colheita Integração pecuária-floresta com produção de feno e integração... |

| The aim of this study was to assess the effect of soil management and planting spacing on establishment performance of mixed swards of purple stargrass (Cynodon nlemfuensis cv. BRS Lua) and forage peanut (Arachis pintoi cv. Belmonte). The treatments comprised two methods of soil management (conventional tillage, with desiccation followed by harrowing; and no-tillage, with sequential desiccation with glyphosate) and two planting spacing (50 and 100 cm between rows). The experimental design was in randomized blocks, arranged in split-plot. Both methods of soil management ensured rapid pasture establishment, with canopy cover greater than 94 % at 84 d after planting, with the no-tillage surpassing the conventional tillage, and at a cost of no-tillage 7 %... |
