“…Millet promoted a lower RP in the layers of 0-0.10 and 0.10-0.20 m. The results of the present study are consistent with those of Almeida et al (2008), who studied crop rotation and physical and chemical attributes in a Red Latosol from the Cerrado under CT and DS, and observed the lowest values of resistance to penetration in the areas cultivated with millet.…”

“…Some studies agree with the present study, indicating a higher compaction in DS caused by the cumulative effect of traffic of machines and natural accommodation of solids particles (Klein & Boller, 1995), especially in the surface layer. Almeida et al (2008) also observed increased values of RP in the surface layer of the soil under DS. In their study, Silva et al (2015) also found higher compaction for DS compared with CT.…”

Soil management alters soil physical attributes and may affect crop yield. In order to evaluate soil physical attributes in layers from 0 to 0.40 m and soybean grain yield, in the 2012/2013 agricultural year, an essay was installed in the experimental area of the Federal University of Mato Grosso do Sul (UFMS/CPCS). Soil tillage systems were: conventional tillage (CT), minimum tillage (MT) and no tillage (DS), the cover crops used were millet, sunn hemp and fallow. The experimental design was randomized blocks with split plots. For the layer of 0.20-0.30 m, millet provided the best results for soil bulk density, macro and microporosity. The resistance to penetration (RP) was influenced in the layer of 0-0.10 m, and millet provided lower RP. The DS provided the lowest RP values for the layer of 0.10-0.20 m. The treatments did not influence yield or thousand-seed weight.

“…In research conducted by SANTOS et al (2006) in a dystrophic Nitosol, applied magnesium thermophosphate ,thermophosphate + lime and thermophosphate + gypsum + stillage , cultivated in systems no-tillage and conventional no-tillage, was found that conventional no-tillage gave higher grain yield of maize compared to the system notillage, agreeing with the results found by DOMINGUES (2004). ALMEIDA et al (2008) found, after three years of installation of soil management systems, the effects of rotation with green manure, corn or soybean (summer) and beans "winter", that systems of crop rotation, cover crops and management of the soil influence the physical and chemical properties of soil and crop productivity bean, corn and soybeans. Similar results were found by CRUZ et al (2009), obtaining better chemical soil conditions and higher grain yield of corn in minimum tillage and no-tillage systems.…”

ABSTRACT:The evaluation of technologies employed at the agricultural production system such as crop rotation and soil preparation, both associated with crop-livestock integration, is crucial. Therefore, the aim of the present study was to evaluate the incorporation of lime for three no-tillage systems and cultural managements in system of crop-livestock integration, with emphasis on corn grain yield. The experiment was conducted from January 2003 to April 2005 at Selvíria city, MS, in Dystroferric Red Latosol, clay texture. The experimental design was randomized blocks with split plots consisted of three main treatments, aimed the soil physics conditioning and the incorporation of lime: PD -No-no-tillage; CM -minimum no-tillage, and PC -conventional no-tillage; and of two secondary treatments related to the management: rotation and crop succession, with four replications. Data on agronomic traits of maize were analyzed: plant height, stem diameter, height of the first spike insertion, 100 grains weight and grain yield. The results showed that the maize produced under the system of croplivestock integration is quite feasible, showing that grain yields are comparable to averages in the region and the different soil physical conditioning and incorporation of lime did not influence the corn yield as well as the cultural managements, rotation and succession, did not affect the maize crop behavior after two years of cultivation.

“…Embora concordando com Almeida et al (2008), os quais concluíram que maior teor de argila confere maior estabilidade aos agregados, a correlação entre os atributos argila e DMG não foi significativa neste estudo, revelando que a variação de outros fatores pode ter interferido nesses resultados. Deve-se atentar que a textura é um atributo indicativo e, para uma análise mais profunda sobre a estabilidade dos agregados, fazse necessária a análise de outros atributos, em conjunto, como DMG dos agregados, teor de C orgânico do solo, aspectos de manejo e clima (Salton et al, 2012).…”

RESUMOA maioria dos estudos relacionados à agregação do solo associa o efeito de manejos ou tipos de uso da terra ao teor de matéria orgânica. No entanto, a avaliação de microrganismos e seus processos, feita diretamente em estruturas indeformadas do solo, permite maior entendimento do real efeito de diferentes tipos de manejos exercidos sobre esse. Assim, o objetivo deste trabalho foi avaliar modificações impostas por diferentes tipos de uso da terra (pastagem, mata de eucalipto, mata com araucária, plantio convencional com cenoura e plantio convencional com abóbora) em atributos químicos (pH, Ca, Mg, Al, P, K, S e matéria orgânica) e físicos (diâmetro médio geométrico -DMG, diâmetro médio ponderado -DMP, densidade do solo e densidade de partículas) e na qualidade microbiana (atividade e carbono microbianos, micélio extrarradicular total de fungos micorrízicos arbusculares e quociente metabólico -qCO 2 ) de classes de tamanho de agregados (I-4,00 a 2,36 mm; II-2,36 a 1,18 mm; III-1,18 a 0,60 mm; IV-0,60 a 0,30 mm; e V-0,30 a 0,15 mm) de um Latossolo Vermelho-Amarelo, no sul de Minas Gerais. Os resultados evidenciaram que os tipos de uso da terra interferem na formação, no tamanho e na qualidade microbiana dos agregados. Em agregados menores (classes IV e V), há redução de micélio extrarradicular de fungos e biomassa microbiana e aumento da atividade e do quociente metabólico, independentemente do tipo de uso da terra. A qualidade microbiana de agregados maiores do solo sob mata de araucária, com tamanho entre 0,60 e 4,00 mm (I, II e III), é semelhante a todas as classes de tamanho de agregados do solo sob mata de eucalipto, enquanto a de agregados menores de 0,60 mm (IV e V) é semelhante a todas de tamanho de agregados da pastagem. Agregados do cultivo convencional, diferentemente dos demais tipos de uso da terra, apresentam baixa qualidade microbiana e relação com a fertilidade do solo.Termos de indexação: estabilidade de agregados, matéria orgânica, sistemas de manejo, microrganismos do solo.
