In Brazil extensive areas are covered with pine forests, planted for pulp and paper production. This industry generates solid alkaline waste, such as dregs. The application of this dregs to forest soils is an alternative for soil acidity correction and plant nutrient supply, as well as a solution for its proper disposal. The purpose of this study was to compare the residual effect of surface application of dregs and dolomitic lime on (a) changes in the physical and chemical properties of an acidic soil and (b) pine tree development. The experiment was carried out in 2004 in Bocaina do Sul, Santa Catarina, consisting of the application of increasing dreg and lime rates to a Pinus taeda L. production area, on a Humic Cambisol, in a randomized block design... |

Instalou-se um experimento no Submédio São Francisco com o objetivo de avaliar o efeito da calagem e gessagem na produtividade e qualidade do tomate e melão. O delineamento foi em blocos ao acaso, com quatro repetições e sete tratamentos: 1) testemunha; 2) 0,5 vezes a necessidade de calagem (N.C.) na forma de calcário (0,5 x N.C. -Ca); 3) 1 x N.C. - Ca; 4) 2 x N.C. -Ca; 5) 0,5 x N.C., na forma de 2/3 de calcário e 1/3 de gesso (0,5 x N.C. - CaGe); 6) 1 x N.C -CaGe ; 7) 2 x N.C. -CaGe. Não se verificou efeitos significativos sobre a produtividade do tomate e a qualidade do melão. Com aplicação de 2 t/ha de calcário (1 x N.C -Ca) obteve-se uma produtividade de melão de 22,52 t/ha, significativamente superior à da testemunha, 16,77 t/ha, e reduziu-se a... |

Silicates can be used as soil correctives, with the advantage of being a source of silicon, a beneficial element to the grasses. However, high concentrations of silicon in the plant would affect the digestibility of the forage. To evaluate the influence of the substitution of the calcium carbonate by calcium silicate on the nutrition, biomass production and the feed quality of the palisade grass [Urochloa brizantha (C. Hochstetter ex A. Rich.) R. Webster], three greenhouse experiments were conducted in completely randomized designs with four replications. Experimental units (pots) contained a clayey dystrophic Rhodic Haplustox, a sandy clay loam dystrophic Typic Haplustox and a sandy loam dystrophic Typic Haplustox. Each soil received substitution... |

In Rio Grande do Sul State (RS), Southern Brazil, aluminum saturation in many areas under no-till system is high and base saturation low in the 0.10-0.20 m layer (subsurface), which may reduce the grain yield of annual crops. The objective of this study was to evaluate if the occurrence of high aluminum saturation and low base saturation in the subsurface, under a no-till system, represents a restrictive environment for crop production, as well as to evaluate forms of lime incorporation for soil acidity correction in the subsurface. For this purpose, an experiment was carried out with soybean (2005/2006), corn (2006/2007), wheat (2007) and soybean (2007/2008) crops, in a Rhodic Hapludox (USDA, 1999) with sandy loam texture, under no-till for four years in... |

In this work lime essential oils were extracted by hydrodistillation and supercritical carbon dioxide. In the case of hydrodistillation, the parameters evaluated were extraction time and characteristics of the plant material. In supercritical extraction, the parameters evaluated were temperature, pressure, CO2 flow, extraction time and material characteristics. Considering citral content, the best results for hydrodistillation were obtained with a distillation time of 3 hours using whole peels. The best results for supercritical extraction were found using 60ºC, 90 bar, at a CO2 flow rate of 1 mL/ min for 30 minutes using milled peels. The best yields of lime oil were obtained by hydrodistillation (5.45% w/w) and supercritical extraction (7.93% w/w) for... |

The reconstitution of soil fertility is essential in the process of pasture restoring, liming being the first action to be taken in this direction. The liming recommendation for pastures needs more technical information as the application method and rate. A field experiment was carried out to evaluate the liming and fertilization practices to restore a degraded Brachiaria decumbens pasture. The following factors were studied: liming method (incorporated in soil by disking or not); level of base saturation (40, 50 or 80%) and lime type (55, 70 or 90 of ECC). Liming and fertilization (NPK and micronutrients) increased both the forage yield and its root system, these being more evident in the second year, even using the same rates of lime and fertilizer used... |

Low shrinkage is an important parameter in marketing of dried lime fruits. An experiment conducted in order to evaluate affective factors on shrinkage coefficient of a dried lime fruit. Factors are defined as position of rest (vertical and horizontal), mechanical processing (length needling, width needling, slotting and intact or no processing), and temperature (shadow dried, sun dried, 40oC, 105oC and 200oC). Measured characters on a fruit were initial volume, final volume, and shrinkage coefficient. The average initial moisture content of limes was 476 % kg (kg db)-1. The position factor had no significant effect on shrinkage coefficient, but mechanical processing and temperature affected the final volume and consequently the shrinkage coefficient... |

Especially under no-tillage, subsuface soil acidity has been a problem, because it depends on base leaching, which has been associated with the presence of low molecular weigth organic acids and companion anions. The objective of this study was to evaluate exchangeable base cation leaching as affected by surface liming along with annual urea side-dressing of maize and upland rice. Treatments consisted of four lime rates (0, 1500, 3000, and 6000 kg ha-1) combined with four nitrogen rates (0, 50, 100, and 150 kg ha-1) applied to maize (Zea mays) and upland rice (Oryza sativa), in two consecutive years. Maize was planted in December, three months after liming. In September of the following year, pearl millet (Pennisetum glaucum) was planted without... |

A erva-mate ocorre naturalmente em solos ácidos, mas é comumente cultivada em consórcio com culturas anuais que requerem correção da acidez. Contudo, pouco se conhece sobre seu comportamento frente à calagem. O objetivo desse estudo foi verificar a influência do calcário no crescimento e estado nutricional de plantas jovens de erva-mate. Para isso, incubou-se o solo com 0,0, 0,7, 1,8, 2,5, 3,4, 4,3 e 5,2 g dm-3 de calcário. Após 21 dias de incubação, mudas de erva-mate foram transplantadas para vasos com 3 dm3 de solo. Após 210 dias determinou-se o crescimento em altura e diâmetro, posteriormente separou-se as plantas em folha, caule e raiz para determinação da área foliar, comprimento e volume de raízes, produção de matéria seca e teor de N, P, K, Ca, Mg,... |

O experimento foi conduzido em laboratorio, com larvas de lagarta-do-cartucho Spodoptera frugiperda (J.E. Smith, 1797). O delineamento experimental foi inteiramente casualizado. As lagartas foram alimentadas com folhas de milho procedentes de um solo corrigido para tres niveis de aluminio atraves de calagem com calcario dolomitico. O consumo foliar foi medido em funcao da area e peso, sendo tambem calculados os indices de consumo e utilizacao. Os resultados mostraram que houve resposta compensatoria, onde a lagarta mudou seu comportamento em relacao a tomada de alimento, procurando compensar as dificuldades na digestao e aproveitamento do alimento, variando a ingestao de folhas sem alterar o desenvolvimento larval, as custas, entretanto, de um maior gasto... |

O trabalho foi realizado com o objetivo de avaliar a influencia da peletizacao de sementes de tres cultivares de sorgo (Sorghum bicolor (L.) Moench), cv. BRS 701, BRS 304 e BRS 601, com calcario e com termofosfato magnesiano, na absorcao de P e de K. Sementes peletizadas e nao peletizadas foram colocadas para germinar, por oito dias, em temperatura ambiente. Apos este periodo, oito plantulas com crescimento uniforme (parte aerea e raiz) foram distribuidas em vasos que continham solucao nutritiva completa de Hoagland. Apos 20 dias, iniciou-se a determinacao da absorcao de fosforo e de potassio por meio da deplecao desses nutrientes na solucao nutritiva. Os resultados permitiram concluir que o tipo de revestimento das sementes influenciou, de modo distinto,... |

Abstract Nine non-lactating Holstein x Gyr cattle were fed with rations based on chopped sugarcane supplied in natura (control) or hydrolyzed (fresh matter basis) for 24 h with 1% or 2% calcium oxide (CaO), which corresponds to 3.1% or 6.2% CaO on a dry matter (DM) basis, respectively. Ruminal parameters (pH and ammonia N, acetate, propionate and butyrate concentrations) as well as the kinetics of fluid and particulate passage in the gastrointestinal tract from cattle were evaluated. A design using three 3 x 3 contemporaneous Latin Squares (LS) was adopted. The studies of kinetics of fluid and particulate passage were performed using the external markers cobalt-EDTA and chromium-mordanted-NDF, respectively. The ruminal parameters were analyzed according to... |
