| Root growth and crop yield can be affected by chemical modifications of the soil profile owing to lime and gypsum applications. A field trial was carried out on a dystrophic Clayey Rhodic Hapludox at Ponta Grossa, PR, Brazil, aiming to evaluate lime (without or with incorporation into the soil) and gypsum effects on root growth, mineral nutrition and grain yield of wheat (cv. OR 1). A randomized complete block design was used, with three replications, in a split-plot experiment. Treatments with dolomitic limestone (without lime and 4.5 t ha-1 of lime applied on the surface, in total rate and 1/3 of the requirement per year during 3 years, or incorporated into the soil) were applied in July 1998 (main plots) and the rates of gypsum (0, 3, 6 and 9 t ha-1) in... |

| Abstract Lime sulphur is used worldwide in agriculture to control pests and diseases. Our objective was to determine the effect of lime sulphur applications in an orange orchard on soil chemical properties and foliar nutrients after seven years of use to control B. yothersi. Soil and leaf samples were collected in two consecutive years for determination of soil chemical properties and nutritional analysis, respectively. We also assessed severity of citrus leprosis and productivity of plants. The applications of lime sulphur reduced pH values in CaCl2 and increased levels of S-SO42- in subsurface soil layer. Plants treated with lime sulphur had thehighestleaf concentrations of Ca and S and of the micronutrients B, Cu, Mn e Zn. On the other hand, lime... |

| Deficiências e desequilíbrios minerais em bovinos são descritas em quase todas as regiões do mundo. Os elementos minerais comumente deficientes para bovinos com dieta exclusiva de pasto são: P, Na, I, Cu, Co, e Se. Em algumas regiões sob condições especificas, Ca, Mg e Mn. Por outro lado, Fe e Mn estão, normalmente, em excesso nas regiões do Cerrado Central do Brasil e Pantanal. A ingestão de dietas deficientes ou desequilibradas de elementos minerais torna mais difícil a manutenção de concentrações ótimas nos tecidos . No inicio, causa lesões bioquímicas que induzem a trocas nas formas de funcionamento, concentração e atividade do elemento nos fluidos e tecidos do corpo. Essas alterações diferem conforme os elementos e suas funções, com o grau de duração... |

| The clinical picture of sulphur (S) deficiency is described by the first time in Brazilian dairy calves. Twelve crossbred six-month-old weaned dairy calves, reared on pasture of S-deficient Brachiaria decumbens, were used. The calves were randomly assigned in two groups of six calves each to verify the influence of S supplementation on some clinical and serum biochemical variables. All animals were fed a basal-supplement mix containing macro and microlements, urea and ground corn grain added (41gS/kg) or not of S (elemental S; 1g S/kg), for six months. At the end of the experiment, the S-supplemented calves had higher mean body weight (p < 0.01), body condition score (p < 0.016), serum inorganic sulphate concentration (p < 0.001) and serum albumin... |
