| O sistema de cultivo de arroz predominante no Brasil, o de terras altas, fica na dependência da precipitação pluvial e de sua distribuição. Determinadas práticas ou distúrbios, que atuam sobre o solo, levam a alterações que os microrganismos, por ser sensíveis, podem detectar. O trabalho objetivou estudar as alterações microbiológicas (carbono da biomassa microbiana (CBM)) e do CO2 (C-CO2) liberado, do quociente metabólico (qCO2) e micorrização), fertilidade do solo e produtividade do arroz de terras altas, cultivado sob diferentes manejos de solo e água. A cultivar utilizada foi a BRS Talento, e o delineamento experimental foi o de blocos casualizados, com quatro repetições. Os tratamentos foram arranjados em fatorial de três manejos de solo: plantio... |

| In order to reduce the impact of decreasing profit margins in crop production systems, all possible options that will increase net profits need to be explored. Land preparation and stool removal in sugarcane production can be a major contributor to overall production costs. Since estimates that mechanization can contribute as much as 50% of the total production costs, considerable savings can potentially be made if the number of tillage operations is reduced. Such savings however, have to be offset against other costs associated with minimum or no-tillage systems, such as the increased need for herbicide. In addition, conventional tillage systems have been implicated in yield decline over the long-term and therefore yield benefits are envisaged, together... |

| O cultivo da erva-mate consorciado com culturas agrícolas anuais nas entrelinhas visa propiciar uma renda adicional ao produtor e diminuir o custo de implantação da cultura principal. Entre as linhas de erva-mate, espaçadas de 6 m, plantadas em 1994, foram cultivadas, a partir de 1995, sete coberturas verdes de inverno: tremoço azul, ervilhaca peluda, aveia preta, azevém comum, nabo forrageiro, vegetação espontânea e uma mistura de ervilhaca, nabo e tremoço. A partir do verão de 1996, foi cultivada soja em diferentes sistemas de preparo do solo: convencional, cultivo mínimo (subsolagem), tração animal, enxada rotativa e plantio direto. A poda de formação da erva-mate foi realizada em agosto de 1998. A primeira poda de produção foi em agosto de 1999, e a... |

| ABSTRACT Soil preparation along with its chemical adjustment is the most important step in sugarcane plantation, especially because it provides proper conditions for plant development. The objective of the present research was to evaluate sugarcane response to the application of different phosphorus doses and their location, associated with both minimum soil tillage and conventional soil tillage. The experiment was conducted in a split-split-plot randomized block design, where the main plots were subjected to soil managements (minimum soil tillage or conventional soil tillage), the subplots to phosphorus doses in total area, and the sub-sub-plots to phosphorus doses in the crop rows. The evaluated variables were soil chemical parameters, sugarcane... |

| The objective of this study was to evaluate potato plant growth and macronutrient uptake, as affected by soil tillage methods, in sprinkle and drip irrigated experiments. Eight treatments were set: T1, no tillage, except for furrowing before planting; T2, one subsoiling (SS); T3, twice rotary hoeing (RH); T4, one disc plowing (DP) + twice disc harrow leveling (DL); T5, 1DP + 2DL + 1RH; T6, 1DP + 2DL + 2RH; T7, 1SS + T6; T8, one moldboard plowing (MP) + 2DL. Treatments were arranged in a randomized block design with four replications. In both irrigation systems, plants presented higher emergence velocity index (EVI), when the soil was not tillaged, and the EVI was inversely related to the maximum tuber dry mass production. In both experiments, a functional... |

| ABSTRACT The need to adapt agricultural crops to climate change and to develop more sustainable cultivation systems has been a major challenge for agriculture. In this study the effects of soil conservation practices were evaluated on production aspects of melon (Cucumis melo), cultivar BRS Araguaia, cultivated in a greenhouse under soil and climatic conditions of the Brazilian Cerrado. The adopted experimental design was of randomized blocks with three treatments (soil managements) and six replicates. We evaluated the following soil management systems: no-tillage (PD), minimum tillage (CM) and conventional tillage (PC) in two cycles. Increases in commercial productivity and average number of marketable fruits were observed for PD (61.5 and 61.2 t/ha;... |

| Recent years have seen a growth of interest in the adoption and diffusion of low-input sustainable agricultural technologies among smallholder agriculturalists in developing countries. This paper examines the adoption of one such technology, labranza minima, a form of minimum tillage, among resource-poor agricultural households in villages in central Honduras. Logistic regression is used to analyze the determinants of adoption of minimum tillage among a sample of 250 agricultural households. The results show that plots with irrigation, plots farmed by their owners and plots with steeper slopes were more likely canididates for minimum tillage adoption. Farmer household characteristics are not generally found to represent significant influences on... |

| ABSTRACT Water erosion, the main factor in soil degradation, is strongly influenced by soil cover and management. The objective of this study was to determine soil and water losses under natural rainfall conditions from 1993 to 2012 in the southern Santa Catarina Plateau, Brazil, in 3.5 × 22.1 m plots with crops in rotation to study the following management treatments: conventional tillage (CT), minimum tillage (MT), and no-tillage (NT), and a treatment with bare soil (BS). The soil cover remaining after tillage was negatively affected by the increase in soil tillage intensity. Soil losses were strongly affected by the management system, while water losses were less affected. Soil losses were 85.29, 6.41, 2.00, and 0.82 Mg ha-1 yr-1 in the BS, CT, MT, and... |
