Summary: | Use of annual cropping between rows of erva-mate (Ilex paraguariensis St. Hil.) is an agroforestry system very popular in southern Brazil, and the main work and income for small and medium farmers. The intensity of soil work, tilling it to seed annual crops, raise some doubts about some damage it can cause to erva-mate root system. It is also not so clear the effect of growing some grass or legume species during the winter as soil cover crops. The objectives of this work were: to test the influence of soil working intensity using different soil tillage systems on cropping soybean and to evaluate soil physical and chemical changes. On a clayey red latosol that has been under use for a long period with wheat/soybean succession, in Embrapa Negócios Tecnológicos, in Ponta Grossa disctrict, Paraná state, rows of erva-mate were planted 6 m apart from each other, to allow growing annual crops on the interrow. It was tested seven different species as soil cover crops during the winter in rotation to soybean seeded on five different soil tillage systems: rototilling, animal track plowing, conventional system, subsoiling and no tillage. Soil was sampled at the beginning of the experiment and five years after, both at the maximum soybean flowering. Due to the great occurrence of weeds, problems to apply herbicides and limitations of its use on erva-mate plantation, the greater the intensity of tillage work the higher was soybean yield. Soybean was the most productive on soil tilled with rototiller and with animal pulled plow. On no tillage system, soybean was the most productive following winter grass species used as soil cover crop; this fact enhances the importance of weed control on this area. Important correlation was found among Ca+Mg and Al+H contents and bulk density and total porosity values in soil surface with average soybean yield. |

A maior ou menor movimentação do solo, no preparo para plantio dos cultivos anuais intercalares à erva-mate, tem gerado dúvidas sobre possíveis prejuízos ao sistema radicular desta. Também não são muito claros os efeitos do uso de gramíneas e/ou leguminosas de inverno como coberturas verdes. Foram objetivos deste trabalho: verificar a influência da movimentação do solo em diferentes sistemas de preparo na implantação de uma cultura de verão nas entrelinhas da erva-mate, em sucessão a coberturas verdes de inverno, e avaliar as modificações das características químicas e físicas do solo. Em Latossolo Vermelho textura argilosa cultivado por longo tempo, em área da Embrapa Negócios Tecnológicos, em Ponta Grossa, PR, foram plantadas linhas de erva-mate, espaçadas 6 m uma da outra, para possibilitar os cultivos de inverno e verão. Foram avaliadas a produção de massa seca dos sete adubos verdes de inverno e de grãos da soja sob cinco diferentes sistemas de preparo do solo: enxada rotativa, aração com tração animal, sistema convencional, cultivo mínimo e plantio direto. As amostragens de solo ocorreram na implantação do trabalho e no quinto ano após o plantio da erva-mate, em ambos na época de florescimento máximo da soja. Em virtude da grande infestação de invasoras na área, à dificuldade e à restrição de aplicação de herbicidas na erva-mate, os sistemas de preparo do solo que possibilitaram maior produtividade da soja foram os que alcançaram maior controle de invasoras. Os sistemas de preparo com movimentação do solo (enxada rotativa e aração por tração animal) foram os mais produtivos. A maior produtividade da soja em sistema de plantio direto foi alcançado em sucessão às gramíneas de inverno (aveia e azevém), atestando a importância do controle das invasoras. Correlações importantes foram observadas entre os teores de Ca+Mg (positiva) e de Al+H (negativa) e os valores de densidade global (positiva) e de porosidade total (negativa) do solo com a produção média de soja.Embrapa Florestas2003-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1604Pesquisa Florestal Brasileira; n. 47 (2003): jul./dez.; 3-18Pesquisa Florestal Brasileira; No. 47 (2003): jul./dez.; 3-181983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1604/635Dedecek, Renato AntonioPhilipowski, João FilipeMedrado, Moacir José Salesinfo:eu-repo/semantics/openAccess2018-03-22T17:55:17Zoai:pfb.cnpf.embrapa.br/pfb:article/1604Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2018-03-22T17:55:17Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
