| 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... |

| 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... |

| ABSTRACT: The influences of byproduct amendments, containing silicon, calcium, magnesium and potassium, on acidic soil quality in Jiaodong Peninsula of China had been studied and compared with that of lime through monitoring physicochemical properties and enzyme activities of acidic soil over a 120-day period. Byproduct amendments (1125, 2250, 4500 and 9000 kg ha-1) and lime 2250 kg ha-1 was applied in the acidic soil. Results showed that both byproduct amendments and lime significantly increased the pH, EC and enzyme activities of soil. The by-product amendments inhibited microbial biomass carbon and soil respiration. Nevertheless, the lime-treated soil had a much more higher level of CO2 emission than the by-product amendments-treated soil. Compared to... |

| A pecuária no Cerrado baseou-se, por muitos anos, na exploração de pastagens nativas. Nas três últimas décadas, o crescimento acentuado do rebanho bovino na região e o incremento de até cinco vezes na capacidade de suporte das pastagens deveu-se ao aumento da área com grandes gramíneas forrageiras, provenientes do continente africano, especialmente as do gênero Brachiaria e o Andropogon gayanus cv. Planaltina. Estabelecidas sem adubação ou com o efeito residual de modestas adubações da cultura do arroz, sem adubação de manutenção e submetidas a manejo inadequado, extensas áreas dessas pastagens encontram-se em variados graus de degradação. A ausência de adubação de reposição durante décadas de extração dos nutrientes tornou necessária a recuperação dessas... |

| ABSTRACT: The Cerrado soils are acid and deficient in calcium and magnesium, which limit crop growth. Also, there is aluminum toxicity for plant roots being necessary using lime to overcome these conditions. The effects of lime levels and methods of lime application in a Red Latosol, were evaluated. A soybean and corn crop rotation were settled, under conventional (disk plowing and harrowing) and no-tillage planting systems, for four years. Cover crops were planted in the dry season, mucuna cultivated after soybean and millet after corn. One lime treatment was included without cover crop under the conventional system. The occurrence of a dry spell period reduced the soybean yield in the first crop, but yield increases were observed due to lime application,... |
