Resumo: The species of cover crops in pre-harvest of maize crop may influence the soil chemical properties. The objective was to evaluate soil fertility due to the use of plant species cover, previously cultivated with maize crop in no-tillage and conventional and subjected to nitrogen. The experiment was conducted at UNESP in Jaboticabal-SP, in an Oxisol clay during the crop years 2000/01, 2001/02 and 2002/03. The experimental design was randomized blocks in split plots with four replications. The treatments consisted of nitrogen (0, 60 and 120 kg N ha-1) and planting systems, and three under no-tillage system with the use of cover crops: Brachiaria, millet, Crotalaria and lablab, and under a conventional tillage. We evaluated at the flowering stage of corn, covering the crop year 2002-2003, the chemical soil layers (0-0.05, 0.05-0.10, 0.10-0.20; 0.20-0.30 m deep). Tillage systems and nitrogen levels influenced differently to the chemical properties of soil layers studied. Regardless of the nitrogen used in the conventional treatment showed lower organic matter content, calcium and value of sum of bases in the topsoil.

Assim, objetivou-se avaliar a fertilidade do solo em função do emprego de espécies de plantas de cobertura, cultivadas anteriormente à cultura do milho em plantio direto e preparo convencional e submetido a doses de nitrogênio. O experimento foi realizado na UNESP em Jaboticabal-SP, em um Latossolo Vermelho distrófico, textura argilosa, durante os anos agrícolas 2000/01; 2001/02 e 2002/03. O delineamento experimental foi em blocos em acaso, em parcelas subdivididas, com 4 repetições. Os tratamentos foram constituídos de doses de nitrogênio (0, 60 e 120 kg de N ha-1) e por sistemas de plantio, tendo três sob sistema de plantio direto com uso de plantas de cobertura: braquiária, milheto, crotalaria e lablab, e um sob sistema de preparo convencional. Avaliou-se no estádio de florescimento do milho, referente ao ano agrícola 2002-2003, os atributos químicos do solo (camadas de 0-0,05; 0,05-0,10; 0,10-0,20; 0,20-0,30m de profundidade). Os sistemas de plantio e as doses de nitrogênio influenciaram diferentemente às propriedades químicas do solo nas camadas avaliadas. Independentemente da dose de nitrogênio utilizada, o tratamento com sistema convencional, apresentou menor conteúdo de matéria orgânica, concentração de cálcio e valor de soma de bases na camada superficial do solo (0-0,05m).UEL2012-06-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/666610.5433/1679-0359.2012v33n3p963Semina: Ciências Agrárias; Vol. 33 No. 3 (2012); 963-978Semina: Ciências Agrárias; v. 33 n. 3 (2012); 963-9781679-03591676-546Xreponame:Semina.
