| ABSTRACT The way the soil is managed can influence its structuring and, consequently, crop yield. Thus, this study aimed to evaluate the effect caused by the management systems plowing followed by two intermediate harrowing operations, intermediate harrowing, chiseling, chiseling followed by intermediate harrowing, cross chiseling followed by intermediate harrowing, and non-tillage on soil and agronomic attributes of the soybean crop. A randomized block design with four replications was used. The percentage of soil cover, soil resistance to penetration, number of plants per meter, longitudinal distribution of seedlings, and soybean yield were evaluated. The data were submitted to analysis of variance by the Tukey test at 5% probability, and use of... |

| ABSTRACT: The effects of natural weathering and different managements performed in agriculture may best be understood by studying the soil roughness. The aim of this study was to evaluate the optimization of the use of pin microrelief meter, an instrument used to determine the soil surface roughness, as the number of readings collected over traditional methodology proposed in the bibliography. The study was conducted in Rio Paranaiba (MG), in a Haplustox soil. The experimental design was completely randomized in a 2×3 factorial design with four replications. There were combined two types of primary tillage: conventional tillage with disc plow (PCAD) and harrow (PCGA), and three amounts of readings (100, 200, and 300 reading points) sampled in each... |

| Soil tillage is a process that accelerates soil organic matter decomposition transferring carbon to atmosphere, mainly in the CO2 form. In this study, the effect of rotary tillage on soil CO2 emission was investigated, including the presence of crop residues on the surface.Emissions were evaluated during 15 days after tillage in 3 plots: 1) non-tilled and without crop residues on soil surface (NTwo), 2) rotary tiller without the presence of crop residues on soil surface (RTwo), and 3) rotary tiller with the presence of crop residues in soil surface (RTw). Emissions from the RTw plot were higher than the other plots, (0.777 g CO2 m-2 h-1), with the lowest emissions recorded in the NTwo plot (0.414 g CO2 m-2 h-1). Total emission indicates that the difference... |

| A manutenção dos resíduos vegetais sobre o solo, o tipo de resíduo e sua velocidade de decomposição são de grande importância no estudo da ciclagem de nutrientes. Este estudo foi desenvolvido na área experimental do IAPAR - Pato Branco-PR, onde foram avaliados seis resíduos de coberturas de inverno: tremoço azul (Lupinus angustifolius L.), ervilhaca comum (Vicia sativa L.), aveia preta (Avena strigosa S.), nabo forrageiro (Raphanus sativus L.), centeio (Secale cereale L.) e trigo (Triticum aestivum L.), sob Sistema Plantio Direto (SPD) e Sistema Cultivo Convencional (SCC) em um Latossolo Vermelho aluminoférrico. Foi avaliado: velocidade de liberação de potássio (K), matéria seca remanescente (MSR) em bolsas de decomposição, teor de carbono orgânico... |

| Das Umbrechen einer Wiese auf maximal 10 cm Tiefe ist eine grosse Herausforderung. An einer Maschinenvorführung des FiBL wurden zwei Pflugmodelle (Överum Variflex, Rumpstad Stoppelploeg), zwei Flachgrubber (Treffler TG 300, Horsch Terrano 3 FX) sowie zwei zapfwellengetriebene Geräte (Rath Geohobel 230, Howard Rotavator 500) im Einsatz verglichen. Alle Maschinen konnten unter den gegebenen Bedingungen die Kunstwiese auf einer Tiefe von maximal 10 cm umbrechen, lieferten jedoch unterschiedliche Resultate. Der Film zeigt, wie die verschiedenen Geräte die Aufgabe bewältigen. Welche Maschine auf welchen Betrieb passt, hängt stark von den Bodenverhältnissen, dem Unkrautdruck und den angebauten Kulturen ab und muss gut überlegt sein. Technische Daten zu den... |

| The work aims to investigate the effects of different soil management strategies on carbon sequestration and total nitrogen in areas of vineyards suffering from loss of soil functionality. Treatments, selected for inter-row management, to re-install soil functionality were based on compost or other organic amendments (COMP), green manure (GM), and dry mulching (DM) strategies using winter legumes and cereals. Cover crops were seeded in fall and mown in late spring, leaved in the ground for mulching in DM or incorporated into the uppermost soil layers in GM. Such approaches were investigated in six vineyards in Italy, six in France, and two vineyards in Slovenia and Turkey. The results showed that COMP significantly increased total organic carbon (TOC)... |

| Ein zentrales Problem im ökologischen Pflanzenbau ist es, die Schwierigkeiten bei der Regulierung der Unkrautflora in den Griff zu bekommen. Neben den direkten Verfahren der Unkrautregulierung (biologische, thermische oder mechanische Maßnahmen), kommen im ökologischen Landbau vor allem indirekten Maßnahmen eine besondere Bedeutung zu. Neben der Fruchtfolge sind weitere indirekte Unkrautregulierungsmaßnahmen, wie Lichtentzug, Saatgutreinigung, Saatgutqualität, Bodenbearbeitung, Standraum der Kulturpflanzen und Sorteneigenschaften zu nennen. |

| O objetivo do presente trabalho foi estudar a influencia da adubacao verde e/ou organica e do fornecimento hidrico sobre o desenvolvimento e produtividade de taro manejado organicamente, alem de avaliar a influencia do manejo e cobertura vegetal sobre indicadores de qualidade do solo (IQS), identificando quais os IQS sao sensiveis a mudanca de manejo na regiao de Paty do Alferes-RJ. Foram realizados, durante tres anos consecutivos em mesma area sob Latossolo Amarelo, cultivos de taro (Colocasia esculenta), em esquemas fatoriais distribuidos em blocos ao acaso, sob sistema organico de producao. Em 2004 o taro foi plantado em monocultivo ou consorciado com Crotalaria juncea, adubado em cobertura com 0 cu 4,5 Mg ha' 1 de composto organico. No ano de 2005 o... |
