| Biochar (carbonized biomass for agricultural use) has been used worldwide as soil amendment and is a technology of particular interest for Brazil, since its "inspiration" is from the historical Terra Preta de Índios(Amazon Dark Earth), and also because Brazil is the world's largest charcoal producer, generating enormous residue quantities in form of fine charcoal and due to the availability of different residual biomasses, mainly from agroindustry (e.g., sugar-cane bagasse; wood and paper-mill wastes; residues from biofuel industries; sewage sludge etc), that can be used for biochar production, making Brazil a key actor in the international scenario in terms of biochar research and utilization). In the last decade, numerous studies on biochar have been... |

| ABSTRACT: The sweet passion fruits is a native species of Brazil. It is very well adapted to tropical regions, and can be found growing in wild conditions or cultivated by small farmers in many regions. It is consumed mainly as a fresh fruit, splitting with a knife in two parts and using a spoon to collect the pulp with the seeds. The concentrated juice, easily extracted from the pulp, can be used to make juice, ice-cream and deserts. Many small farmers grow sweet passion fruit as an ornamental plant, particularly because of the beauty flowers and colored fruits. In additon it is considered as a medicinal species to treat stress, anxiety and sleeplessness. The ofter of fresh sweet passion fruit in most fruit and grocery stores is still very limited, and... |

| Este trabalho foi elaborado com o objetivo de reunir as informacoes disponiveis sobre a correcao de solo e adubacao de seringueira nas suas diferentes fases, nas condicoes de Cerrado, de modo a atender essa demanda dos heveicultores da regiao. Com base nas analises de solo e planta, sao feitas recomendacoes de calagem, fosfatagem e adubacao de mudas, jardins clonais, plantio, formacao e producao de seringais. |

| ABSTRACT: The Cerrado soils are acid with toxic levels of aluminum, being necessary to use lime to overcome these conditions to grow crops. The residual effect of lime in a Red Latosol were evaluated for corn at the 5th and 6th crop, under conventional tillage (disk plowing and harrowing) and no-tillage planting systems. Lime at different levels was previously applied for the first crop, with and without incorporation into the soil. The results showed a significant increase in corn grain production due to the residual effects of lime levels, either incorporated, surface applied with no incorporation, or a mixing of both methods. After six years of cropping, the surface applied lime with no incorporation changed the soil conditions mainly at the 0 cm - 10... |

| This pot study investigated the effect of the combined application of two commercial biofertilizers viz. Biopower and EM (Effective Microorganisms) on rice (Oryza sativa L.) growth and yield in soils amended with farmyard manure, green manure, and NPK fertilizers. Biopower is a product of the Nuclear Institute for Biotechnology and Genetic Engineering (NIBGE), Pakistan, which contains species of associative and endophytic diazotrophs. EM (effective microorganisms), a product developed by Japanese scientists, consists of co-existing beneficial microorganisms, mainly species of photosynthetic and lactic acid bacteria, as well as yeast. Applying Biopower adversely affected plant growth and yield in NPK fertilizer amendment. Conversely, this biofertilizer... |

| Rhizosphere soil samples were collected in a semiarid area, in the region of the São Francisco River valley, Petrolina, Pernambuco state, Brazil, to study the diversity of filamentous fungi in a soil cultivated with melon (Cucumis melo L. cv. Gold Mine) and receiving different organic amendments: Treatment 1 (control, without organic compost); T2 (77% coconut fiber, 20% goat manure and 3% K2SO4); T3 (10% Ricinus communis leaves and stems, 50% Pennisetum purpureum leaves and 40% goat manure); T4 (77% coconut fiber, 20% goat manure and 3% termophosphate); T5 (47% Pennisetum purpureum leaves, 50% goat manure and 3% K2SO4); and T6 (57% Pennisetum purpureum leaves, 40% goat manure and 3% termophosphate). Fungal isolation was carried out by the serial dilution... |

| Como subproducto del tratamiento de las aguas residuales de la ciudad de Aguascalientes, Ags., en la Planta de Tratamiento “El Niágara”, se generan diariamente de 150 a 170 m3 de biosólidos. Estos materiales son aplicados a suelos agrícolas de áreas cercanas a la planta, sin regulación alguna, por lo que se han obtenido buenos resultados o causado quemaduras en plántulas o endurecimiento de suelos. El objetivo de este proyecto fue generar estrategias para la disposición y aprovechamiento de los biosólidos para mejorar suelos agrícolas y la calidad y rendimiento de los cultivos, sin perjuicio para el ambiente. Para determinar el efecto de los biosólidos sobre suelos y plantas, se colectaron muestras de los biosólidos y se tomaron muestras de tres tipos de... |
