Em muitos casos, a substitui\uffc3\uffa7\uffc3\uffa3o da vegeta\uffc3\uffa7\uffc3\uffa3o nativa por sistemas agr\uffc3\uffadcolas resulta em decr\uffc3\uffa9scimo nos conte\uffc3\uffbados de C e N nos diferentes compartimentos da mat\uffc3\uffa9ria org\uffc3\uffa2nica do solo. Para testar se as pr\uffc3\uffa1ticas de manejo que priorizam o aporte de res\uffc3\uffadduos org\uffc3\uffa2nicos promovem aumento dos compartimentos da mat\uffc3\uffa9ria org\uffc3\uffa2nica mais sens\uffc3\uffadveis ao manejo, este estudo se prop\uffc3\uffb4s estudar \uffc3\uffa1reas de uma propriedade que utiliza um sistema de produ\uffc3\uffa7\uffc3\uffa3o de acerola em larga escala, sob manejo org\uffc3\uffa2nico, e uma \uffc3\uffa1rea sob cultivo convencional de cenoura e beterraba em rota\uffc3\uffa7\uffc3\uffa3o com milho, pertencentes \uffc3\uffa0 Fazenda Amway Nutrilite do Brasil e \uffc3\uffa0 Associa\uffc3\uffa7\uffc3\uffa3o de Horticultores do Pivot Central, respectivamente, ambas localizadas na regi\uffc3\uffa3o da Chapada da Ibiapaba, Cear\uffc3\uffa1. Selecionou-se, tamb\uffc3\uffa9m, uma \uffc3\uffa1rea de pastagem localizada no interior da primeira propriedade amostrada, bem como \uffc3\uffa1reas sob mata nativa, pr\uffc3\uffb3ximas \uffc3\uffa0s \uffc3\uffa1reas de cultivo. Amostras de um Neossolo Quartzar\uffc3\uffaanico foram coletadas nas profundidades de 0-5 e 5-15 cm e foram determinados os teores de C org\uffc3\uffa2nico total, de C e N microbiano (Cmic e Nmic) e da mat\uffc3\uffa9ria org\uffc3\uffa2nica leve (Cmol e Nmol), al\uffc3\uffa9m do C mineraliz\uffc3\uffa1vel obtido por respirometria. O ac\uffc3\uffbamulo m\uffc3\uffa9dio nos estoques de Nmic nas \uffc3\uffa1reas sob manejo org\uffc3\uffa2nico em rela\uffc3\uffa7\uffc3\uffa3o \uffc3\uffa0 mata nativa foi de 11,7 kg ha-1, o que representou um incremento de 585 % de Nmic nas \uffc3\uffa1reas de cultivo. J\uffc3\uffa1 na pastagem, ocorreu ac\uffc3\uffbamulo de 211 kg ha-1 no estoque de Cmic em rela\uffc3\uffa7\uffc3\uffa3o \uffc3\uffa0 mata nativa em subsuperf\uffc3\uffadcie, representando um incremento de 514,6 %. Por outro lado, os estoques de Cmic no cultivo convencional sofreram redu\uffc3\uffa7\uffc3\uffb5es de 59 e 53 %, nas camadas de 0-5 e de 5-15 cm, respectivamente, em rela\uffc3\uffa7\uffc3\uffa3o \uffc3\uffa0 mata nativa. Os estoques de Cmol obtidos nas linhas de cultivo nos sistemas org\uffc3\uffa2nicos apresentaram incremento de 106 %, na camada de 0-5 cm, em rela\uffc3\uffa7\uffc3\uffa3o \uffc3\uffa0 mata; no sistema convencional, por\uffc3\uffa9m, constatou-se uma redu\uffc3\uffa7\uffc3\uffa3o em 31 % no estoque de Cmol na camada superficial. Os resultados indicaram que o manejo realizado nas \uffc3\uffa1reas sob cultivo org\uffc3\uffa2nico com acerola e pastagem contribuiu para a manuten\uffc3\uffa7\uffc3\uffa3o e recupera\uffc3\uffa7\uffc3\uffa3o dos conte\uffc3\uffbados de C e N da biomassa microbiana (BMS) e da mat\uffc3\uffa9ria org\uffc3\uffa2nica leve (MOL) do solo. Os incrementos e, ou, redu\uffc3\uffa7\uffc3\uffb5es de C e N nos compartimentos BMS e MOL, comparativamente \uffc3\uffa0 \uffc3\uffa1rea nativa de refer\uffc3\uffaancia, foram proporcionalmente maiores que os valores obtidos, quando considerados somente os estoques de C org\uffc3\uffa2nico e N totais, principalmente na \uffc3\uffa1rea sob sistema de cultivo convencional. Isto indica serem tais compartimentos sens\uffc3\uffadveis \uffc3\uffa0s mudan\uffc3\uffa7as no estado da mat\uffc3\uffa9ria org\uffc3\uffa2nica de acordo com o manejo. Os sistemas de manejo org\uffc3\uffa2nico e pastagem constituem estrat\uffc3\uffa9gias de manejo importantes que devem ser consideradas para a conserva\uffc3\uffa7\uffc3\uffa3o e, ou, aumento da mat\uffc3\uffa9ria org\uffc3\uffa2nica e, conseq\uffc3\uffbcentemente, para a melhoria da qualidade do solo e implementa\uffc3\uffa7\uffc3\uffa3o do seq\uffc3\uffbcestro de C na regi\uffc3\uffa3o da Chapada da Ibiapaba, Cear\uffc3\uffa1.

This study aimed to evaluate physical attributes of a Yellow Latossol under different management systems in the savanna area in the state of Piaui. This study was developed in Uru\uffc3\uffa7u\uffc3\uffad southwest of the state of Piau\uffc3\uffad. Three systems of soil management were studied: an area under conventional tillage (CT) with disk plowi and heavy harrow and soybean crop; an area under no-tillage with soybean-maize rotation and millet as cover crop (NT + M); two areas under Integrated Crop-Livestock System, with five-month pasture grazing and soybean cultivation and then continuous pasture grazing (ICL + S and ICL + P, respectively). Also, an area under Native Forest (NF) was studied. The soil depths studied were 0.00-0.05, 0.05-0.10 and 0.10-0.20 m. Soil bulk density, as well as porosity and stability of soil aggregates were analyzed as physical attributes. Anthropic action has changed the soil physical attributes, in depth, in most systems studied, in comparison to NF. In the 0.00 to 0.05 m depth, ICL + P showed higher soil bulk density value. As to macroporosity, there was no difference between the management systems studied and NF. The management systems studied changed the soil structure, having, as a result, a small proportion of soil in great aggregate classes (MWD). Converting native forest into agricultural production systems changes the soil physical quality. The Integrated Crop-Livestock System did not promote the improvement in soil physical quality.
