“…Bloomfield et al, 2006;Beulke et al, 2007). Pesticide fate and behaviour will also be influenced by many indirect effects of climate change including, for example, changes in cropping patterns and crop growth Fogelfors et al, 2009), pesticide application rates (Koleva et al, 2009;Kattwinkel et al, 2011), and soil conditions affecting fate processes such as changes in soil organic carbon content or climate induced freezing/thawing cycles (Stenrød et al, 2008).…”

“…Longterm effects are much less documented. Cold climatic conditions prolong the persistence of pesticides in countries like Norway, whilst freezing and thawing events make the leaching and biodegradation of the pesticides much more unpredictable than in more stable climates (Rotich et al, 2004;Stenrød et al, 2005Stenrød et al, , 2007. This may result in effects on earthworm populations that are not considered in the pesticide approval procedure.…”

In order to assess long-term effects on productivity, environmental impacts and soil fertility of contrasting farming practices, six cropping systems, ranging from conventional arable without livestock to organic mixed dairy farming with few arable crops, have been compared since 1989 on a loam soil. A decline in soil structure quality was found in a conventional arable system with annual ploughing with no rotational grass. This system had higher bulk density and mean aggregate size than other systems, and lower levels of plant available water and aggregate stability. Opposite trends were related to the proportion of grass leys in the other systems and to their levels of soil organic matter. The latter declined markedly over 15 years in the conventional arable system, and there were smaller declines in most other systems. In an arable system without ploughing, but with rotary tillage in spring, organic matter was maintained and high structural stability was found. This system had high bulk density, but the proportion of small aggregates equalled that found in systems with ley. There were overall increases in earthworm density (84%), earthworm biomass (80%) and the density of earthworm channels (132%) in the topsoil between 1994 and 2004. Most of these increases were found in systems with 1-3 years of ley in the 4-year rotation. Low values of all earthworm parameters, and only minor changes over the period studied, were found in two non-organic arable systems without ley, indicating high pressure on soil fauna. Lower earthworm activity was found in the non-organic arable system with reduced tillage as compared to the non-organic arable system with annual ploughing. Thus, 50% leys in the rotation appeared desirable for the maintenance of satisfactory soil structure and earthworm activity. Though the deterioration of soil structure in the conventional arable system was not extreme, as the soil was well structured initially, the results may have implications for the sustainability of stockless arable systems on soils with a less favourable initial structure. #

“…Ressalta-se que na precipitação acumulada de 116 mm nas duas avaliações finais aos 10 e 12 DAS, novamente sintoma algum de fitotoxicidade foi verificado nas plantas de pepino evidenciando que a quantidade de herbicida existente na camada de 0-30 cm não foi suficiente para determinar injúrias visuais às plantas de pepino, o que indicou a ocorrência de uma lixiviação intensa do herbicida (Tabela 6). Segundo Stenrød et al (2008) a dissipação de pesticidas em condições de campo é regida pela degradação, sorção e pelos processos transporte, os quais têm uma variabilidade intrínseca, além de variar amplamente em toda a área agrícola, o que dificulta a interpretação dos resultados da área de estudo, mesmo que as principais perdas sejam conhecidas; assim, fatores como textura do solo, quantidade da matéria orgânica e sua origem, temperatura e a intensidade da chuva recebida, podem ter atuado nesses resultados ora obtidos.…”

R E S U M OObjetivou-se, neste trabalho, avaliar o potencial de lixiviação do herbicida metribuzin com precipitações pluviométricas naturais, em dois solos com texturas contrastantes, argiloso e médio arenoso, em condições de campo, através de planta bioindicadora. Colunas de PVC foram introduzidas nos dois solos. Manteve-se a integridade original do solo durante a coleta das amostras, que ocorreu após o acúmulo das precipitações em um intervalo estipulado ao ambiente entre 30-40, 60-80 e 100-120 mm de chuva. As colunas foram separadas com corte longitudinal para a semeadura da espécie bioindicadora (25 plantas). Após a semeadura avaliações de fitotoxicidade das plantas bioindicadoras foram realizadas aos 5, 7, 10 e 12 dias após a semeadura, através de uma escala de notas de 0 a 100%. A lixiviação do herbicida metribuzin foi dependente da precipitação recebida para os dois tipos de solo estudados. A eficácia da planta bioindicadora dependeu do tipo de solo e da precipitação. A metodologia de utilização de plantas bioindicadoras mostrou-se eficiente para avaliação da mobilidade de herbicida no perfil do solo.Rain amount and leaching of the herbicide metribuzin through bioindicator plant A B S T R A C TThe objective of this study was to evaluate the potential for leaching of the metribuzin herbicide under natural rain in two soils with contrasting textures, clay and medium sandy soil under field conditions using bioindicator plant. PVC columns were introduced in both soils maintaining the original integrity of the soil during the sampling that occurred after accumulation of precipitation stipulated in the interval in ambient, between 30-40, 60-80 and 100-120 mm of rain. The columns were separated by longitudinal section for the sowing of bioindicator plant (25 plants). After sowing, phytotoxicity evaluations of bioindicator plant were conducted at 5, 7, 10 and 12 days after sowing through a scale from 0 to 100%. The leaching of the herbicide metribuzin was dependent on the precipitation received in the two studied soil types. The effectiveness of the bioindicator plant depends on the type of soil and amount of precipitation. The method using bioindicator plant proved to be efficient for the evaluation of the mobility of herbicide in the soil profile. Palavras-chave:mobilidade dinâmica Cucumis sativus textura do solo
