The experiment was carried out in Embrapa Rice &amp;amp; Beans, in Santo Ant&amp;ocirc;nio de Goi&amp;aacute;s, GO, Brazil, in a Dystrophic Red Latosol (Red Oxisol).&lt;em&gt; Brachiaria brizantha&lt;/em&gt;,&lt;em&gt; &lt;/em&gt;corn (&lt;em&gt;Zea mays&lt;/em&gt; L.) associated with &lt;em&gt;B. brizantha&lt;/em&gt;, pigeon pea, millet, &lt;em&gt;Panicum maximum&lt;/em&gt;, sorghum, &lt;em&gt;Stylosanthes guianensis&lt;/em&gt;, and sunn hemp&lt;em&gt; &lt;/em&gt;were used as cover crops. Sixty days after the cut of the cover crops, common bean crop was implanted, under a central pivot sprinkler irrigation system. In November 2001, 2005, and 2006, soil samples were collected in the depths of 0-5 cm, 5-10 cm, and 10-20 cm. Immediately after the 2005 sampling, it was applied 4,000 kg ha&lt;sup&gt;-1&lt;/sup&gt; of dolomitic lime, in all the experimental area. Cover crops affected soil pH and magnesium content in the superficial layer. Soil under millet showed higher phosphorus content in subsuperficial layers, in relation to the initial values. The soil P and Cu contents were higher in the subsuperficial layers, while the other chemical attributes were higher in the superficial layer. There was movement of Ca and Mg in the soil profile, one year after the application of lime in the soil surface.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt; &lt;p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="pt-BR" align="JUSTIFY"&gt;&lt;span style="color: #000000;"&gt;&lt;span style="font-family: Times New Roman,serif;"&gt;&lt;span style="font-size: x-small;"&gt;&lt;span style="font-size: small;"&gt;&lt;span lang="en-US"&gt;KEY-WORDS: No-tillage system; grasses; &lt;/span&gt;&lt;/span&gt;&lt;span style="font-size: small;"&gt;&lt;span lang="en-US"&gt;&lt;em&gt;Leguminosae&lt;/em&gt;&lt;/span&gt;&lt;/span&gt;&lt;span style="font-size: small;"&gt;&lt;span lang="en-US"&gt;; soil fertility.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;<br>&lt;span style="color: #000000;"&gt;&lt;span style="font-family: Times New Roman,serif;"&gt;&lt;/span&gt;&lt;/span&gt; &lt;br /&gt;&lt;p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="pt-BR" align="JUSTIFY"&gt;&lt;span style="color: #000000;"&gt;&lt;span style="font-family: Times New Roman,serif;"&gt;&lt;span style="font-size: small;"&gt;Avaliaram-se os efeitos de culturas de cobertura implantadas anualmente no ver&amp;atilde;o, desde 2001, em sistema plantio direto, sobre os atributos qu&amp;iacute;micos do solo. O experimento foi conduzido na Embrapa Arroz e Feij&amp;atilde;o, em Santo Ant&amp;ocirc;nio de Goi&amp;aacute;s, GO, em Latossolo Vermelho distr&amp;oacute;fico. Utilizaram-se as seguintes culturas de cobertura: braqui&amp;aacute;ria, milho consorciado com braqui&amp;aacute;ria, guandu, milheto, capim momba&amp;ccedil;a, sorgo, estilosantes e crotal&amp;aacute;ria. Sessenta dias ap&amp;oacute;s o corte das coberturas, implantou-se a cultura do feijoeiro, sob irriga&amp;ccedil;&amp;atilde;o por aspers&amp;atilde;o, em sistema piv&amp;ocirc; central. Em novembro de 2001, 2005 e 2006, coletaram-se amostras de solo, nas profundidades de 0-5 cm, 5-10 cm e 10-20 cm. Logo ap&amp;oacute;s a coleta de 2005, foram aplicados 4.000 kg ha&lt;sup&gt;-1&lt;/sup&gt; de calc&amp;aacute;rio dolom&amp;iacute;tico, em toda a &amp;aacute;rea experimental. As culturas de cobertura afetaram o pH e o teor de magn&amp;eacute;sio do solo, na camada superficial. O solo sob milheto apresentou maiores teores de f&amp;oacute;sforo, nas camadas subsuperficiais, em rela&amp;ccedil;&amp;atilde;o aos teores iniciais. Os teores de f&amp;oacute;sforo e cobre foram maiores nas camadas subsuperficiais do solo, enquanto os demais atributos qu&amp;iacute;micos apresentaram maiores valores na camada superficial. Houve movimenta&amp;ccedil;&amp;atilde;o de Ca e Mg no perfil do solo, um ano ap&amp;oacute;s a aplica&amp;ccedil;&amp;atilde;o do calc&amp;aacute;rio na superf&amp;iacute;cie.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt; &lt;p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="pt-BR" align="JUSTIFY"&gt;&lt;span style="color: #000000;"&gt;&lt;span style="font-family: Times New Roman,serif;"&gt;&lt;span style="font-size: small;"&gt;PALAVRAS-CHAVE: Sistema plantio direto; gram&amp;iacute;neas; leguminosas; fertilidade do solo.&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
