Resumo: The objective of this work was to evaluate the physical quality of soil in pastures under continuous grazing. The pastures were established with Bermudagrass coastcross (Cynodon dactylon) intercropped or not with the perennial peanut (Arachis pintoi). The intercropped pasture was fertilized with 0, 100 and 200 kg ha-1 nitrogen (N) per year and the single-cropped pasture was fertilized with 200 kg ha-1 N per year, totaling four treatments. The experiment was established in 2002 in a Haplorthox (Rhodic Ferralsol) in Paranavaí, northwestern of Paraná, Brazil, using a randomized complete block design, with two replications. Between 2002 and 2007 the stocking rate was based on forage offer level. In March and November 2007, undisturbed soil samples were collected from 0–75 and 75–150 mm depths for the evaluation of soil bulk density, soil porosity, and soil air and water storage capacity. Continuous grazing with stocking rates controlled as a function of the pasture production did not damage the soil physical quality. The soil water storage capacity is a sensitive indicator to assess the effects of stocking rate intensification on soil physical quality.

O objetivo deste trabalho foi avaliar a qualidade física do solo em pastagens submetidas ao pastejo contínuo. As pastagens foram formadas com capim-coastcross (Cynodon dactylon) consorciado ou não com a leguminosa amendoim forrageiro (Arachis pintoi). A pastagem consorciada recebeu os tratamentos de 0, 100 e 200 kg ha-1 de nitrogênio (N) por ano e a pastagem sem consórcio recebeu 200 kg ha-1 de N por ano, no total de quatro tratamentos. O experimento foi implantado em 2002, em Latossolo Vermelho distrófico, em Paranavaí, PR, em delineamento de blocos ao acaso, com duas repetições. A taxa de lotação animal foi controlada em função da oferta de forragem, entre 2002 e 2007. Em março e novembro de 2007 foram coletadas amostras indeformadas de solo, nas camadas 0–75 e 75–150 mm de profundidade, para determinação da densidade, porosidade e capacidade de armazenamento de ar e de água do solo. O pastejo em sistema de lotação contínua, com controle da taxa de lotação animal em função da produção de forragem, não comprometeu a qualidade física do solo. A capacidade de armazenamento de água do solo é um indicador sensível para se avaliarem os efeitos da intensificação da utilização da pastagem sobre a qualidade física do solo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFidalski, JonezTormena, Cássio AntonioCecato, UlyssesBarbero, Leandro MartinsLugão, Simony Marta BernardoCosta, Marco Aurélio Teixeira2008-12-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/961Pesquisa Agropecuaria Brasileira; v.43, n.11, nov. 2008; 1583-1590Pesquisa Agropecuária Brasileira; v.43, n.11, nov. 2008; 1583-15901678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/961/5560info:eu-repo/semantics/openAccess2012-06-17T11:45:09Zoai:ojs.seer.sct.embrapa.br:article/961Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:45:09Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
