This study investigated Cu uptake and accumulation as well physiological biochemical changes in grapevines grown soils containing excess Cu. The were collected during two productive cycles from three vineyards with increasing concentrations of the soil at various growth stages, before after application Cu-based fungicides. grapevine organs macronutrients parameters leaf blades analyzed. At close to flowering stage grapevines, concentration content leaves increased. However, roots, stem,...
The purpose of this study was to evaluate the mobility copper (Cu) and zinc (Zn) in profile distribution sandy soil fractions from vineyards. Soil samples were collected two vineyards different ages (14 30 years) a natural field area south Brazil. chemical characteristics, Cu levels Zn levels, analyzed soils by extraction with ethylenediamine tetraacetic acid (EDTA) using 3050B method USEPA fractionation. accumulated vineyard soils, especially uppermost layers oldest vineyard. Approximately,...
High rates and successive applications of pig slurry can cause nutrient transfer by surface runoff. The aim this study was to evaluate the importance runoff in transferring nitrogen (N), phosphorus (P) potassium (K) under a no tillage system for slurry. research carried out Agricultural Engineering Department Federal University Santa Maria, Brazil, from 2002 2007 Typic Hapludalf soil. Pig 0, 20, 40 80 m3 ha−1 were applied, scattered on surface, before sowing each species cultivation...
As aplicações sucessivas de dejeto líquido suínos no solo podem aumentar os teores e alterar as formas Cu Zn solo. O presente trabalho teve como objetivo estimar o acúmulo suas em submetido a suínos, sistema plantio direto com rotação culturas. foi desenvolvido um Argissolo Vermelho distrófico arênico na área experimental do Departamento Engenharia Agrícola da Universidade Federal Santa Maria (RS). Os tratamentos consistiram aplicação 0, 20, 40 80 m³ ha-1 suínos. Foram realizadas 17 dejetos...
Successive applications of pig slurry to soils under no-tillage can increase the nutrient levels in uppermost soil layers and part nutrients may be transferred deeper layers. The objective was evaluate distribution profile a after 19 for 93 months. experiment conducted from May 2000 January 2008 an experimental area Federal University Santa Maria, southern Brazil, on Typic Hapludalf. treatments consisted (0, 20, 40 80 m³ ha-1) at end experiment, samples were collected (layers 0-2, 2-4, 4-6,...
Pig slurry application as soil manure can alter the chemical properties of and affect its acidity, modifying environment for crop growth development. The objective this study was to evaluate related acidity subjected successive applications pig slurry. experiment conducted in May 2000, an experimental area Federal University Santa Maria (UFSM) under no-tillage lasted until January 2008. Nineteen surface 0, 20, 40, 80 m³ ha-1 were performed, during a period 100 months sampled end (layers 0-2,...
Successive applications of pig slurry and deep litter may lead to an accumulation copper (Cu) zinc (Zn) fractions in the soil profile. The objective this study was evaluate Cu Zn forms a Sandy Typic Hapludalf after long-term application litter. In March 2010, eight years initiating experiment Braço do Norte, Santa Catarina (SC), Brazil, on soil, samples were collected from 0-2.5, 2.5-5.0, 5-10 10-15 cm layers treatments consisting no manure (control) with at two levels: single double rate N...
No-till farming and manure application are means of storing carbon in soil increasing quality. However, the organic fertilization no-till soils may sustain subtropical agroecosystems for only a limited period until quality declines. The C, N, P, other nutrient cycles perturbed due to imbalance manures their on surface, which poses risk dispersion into environment. Long-term N-based also impacts apparent recovery (ANR) by crops and, hence, crop Our objective was monitor changes measure from...
A suinocultura tem grande importância social e econômica no Brasil. Contudo, os dejetos cada vez mais representam potenciais contaminantes do ambiente, que uma opção à nutrição de plantas. aplicação líquidos suínos pode resultar em perdas elementos, principalmente nitrogênio fósforo, resultando menor eficiência utilização pelas plantas aumentando riscos contaminação da água. Esse trabalho teve por objetivo avaliar a percolação fósforo área submetida aplicações sistemáticas dejeto líquido...
A irrigação das culturas aumenta a possibilidade de obtenção altas produtividades, mas exige racionalidade técnica e econômica no uso insumos, especialmente fertilizantes nitrogenados. O objetivo deste trabalho foi determinar as doses mais adequadas nitrogênio potássio para maior produtividade grãos o melhor retorno econômico da adubação com cultivo milho (Zea mays L.) sob por aspersão. experimento conduzido nos anos agrícolas 2002/03 2003/04, em Cruz Alta, Rio Grande do Sul, lavoura pivô...
O objetivo deste trabalho foi quantificar as frações de acumulação fósforo em solo submetido a sucessivas aplicações dejetos líquidos suínos (DLS) sistema plantio direto. Em Santa Maria, RS, doses 0, 20, 40 e 80 m³ ha-1 DLS foram distribuídas lanço por sete anos agrícolas, antes do cada cultivo inverno ou verão, Argissolo Vermelho arenoso, totalizando 584, 1.168 2.336 kg P aplicado via dejetos. coletado nas camadas 0-2, 4-6, 8-10, 14-16 20-25 cm, ao fracionamento químico P. A adição durante...
Systematic pig slurry application to crop soils may lead the accumulation of heavy metals in regions with intensive raising. The aim this study was evaluate Cu, Zn and Mn under systematic application. For purpose, soil samples were collected from two most representative watersheds Santa Catarina where predominant activity is In each watershed, 12 properties chosen different systems husbandry (complete cycle (CC), farrowing (FaU) finishing units (FiU)). Based on information producers, areas...
O nitrogênio (N) aplicado na superfície do solo em vinhedos pode ser perdido por volatilização ou lixiviação, sendo uma das possíveis explicações para o baixo aproveitamento de N pelas videiras. trabalho objetivou avaliar as perdas e lixiviação mineral cultivado com videira submetida à adubação nitrogenada. Foram instalados dois experimentos um vinhedo Cabernet Sauvignon, Rosário Sul (RS), Brasil. No experimento 1, foram lisímetros no que recebeu a aplicação 0, 40, 80 120kg ha-1 ano-1 forma...
Pig slurry (PS) represents an important nutrient source for plants and using it as fertilizer makes greater cycling in the environment possible.
