Resumo: | The physical and microbiological soil properties have been widely used in monitoring its quality. This is of great importance in determining the impactful as soil management can be., which are very important for determining how impactful a soil management may be, have been widely used for monitoring soil quality. Thus, the objective of this study was to evaluate the physical and microbiological soil characteristics under cultivation and crop successions systems for ten years, in an Ultisol. The no-tillage (PD) and conventional tillage (PC), and succession crops of corn-beans (M-F) and soybean- wheat (S-T) were evaluated. For this, a field experiment in a split plot design was used, where the plots were the no-tillage (PD) and tillage (PC) systems and the subplots were the crop successions, corn-bean (M-F) and soybeans -wheat (S-T), in a completely randomized design with four replications, to physical characteristics of the soil, and three replicates for soil microbiological characteristics. Bulk density (Ds), macroporosity (Mac), microporosity (Mic), total porosity (Pt), organic matter content (MO) in the depths of 0-5; 10-15 and 20-25 cm; soil penetration resistance (RP) to a depth of 60 cm, microbial biomass carbon (MBC), soil respiration rate (C-CO2), metabolic quotient (qCO2) , microbial quotient (qMIC) and the content of total organic carbon (COT) in the depths of 0-5; 5-10 and 10-15 cm were all evaluated. Higher microporosity and total porosity of the soil was found at 0-5 cm depth in no-tillage system when C-B succession was cultivated. Bulk density was lower in both 10-15 cm and 20-25 cm depths when using the conventional tillage. Higher values of organic matter in the surface were found in the corn-bean succession in the no-tillage system. There was greater variation in the soil penetration resistance in the 5-25 cm depth, with higher RP at S-T succession in no-tillage system and reduced RP in the M-F succession in conventional tillage. Soil respiration rate differ between crop succession only in the 0-5 cm depth, which was greater for C-B succession. Conventional tillage presented higher amount of total organic carbon than no-tillage system at depths of 5-10 and 10- 15 cm. The qCO2 differed between crop successions at the depth of 10-15 cm, where the soil with the M-F succession presented the highest value. The physical and microbiological soil characteristics were affected by the tillage systems and crop ix successions after ten years. The no-tillage system yielded improvements in some physical soil properties in comparison to conventional tillage in the first 5 cm of soil after ten years of use. The cultivation M-F succession resulted in higher porosity in the soil surface and in the subsurface. The crop successions affected soil respiration rate only in the lower depth. An increased activity of microorganisms in soil is found when using the bean-corn succession crop. |

Assim, objetivou avaliar as características físicas e microbiológicas do solo sob sistemas de plantio e sucessões de culturas por dez anos, em um Argissolo Vermelho-Amarelo. Foram avaliados os sistemas plantio direto (PD) e plantio convencional (PC) e as sucessões de culturas milho-feijão (M-F) e soja-trigo (S-T). Para isso, utilizou-se um experimento de campo em esquema de parcelas subdivididas, tendo nas parcelas os sistemas de plantio direto (PD) e convencional (PC) e, nas subparcelas, as sucessões de culturas, milho-feijão (M- F) e soja-trigo (S-T), no delineamento inteiramente casualizado com quatro repetições, para caracteristicas física do solo, e três repetições, para caracteristicas microbiologicas do solo. Avaliaram-se a densidade do solo (Ds), macroporosidade (Mac), microporosidade (Mic), porosidade total (Pt), teor de matéria orgânica nas profundidades de 0-5, 10-15 e 20-25 cm, resistência mecânica do solo à penetração (RP) até a profundidade de 60 cm, carbono da biomassa microbiana (CBM), taxa respiratória dos microrganismos no solo (C-CO2), quociente metabólico (qCO2), quociente microbiano (qMIC) e teor de carbono orgânico total (COT) nas profundidades de 0-5, 5- 10 e 10-15 cm. O solo sob plantio direto, na profundidade de 0-5 cm, apresentou maior microporosidade e porosidade total do solo quando cultivada a sucessão M-F. A densidade do solo foi menor quando utilizado o plantio convencional, tanto na profundidade de 10-15 cm, quanto na de 20-25 cm. Maiores teores de matéria orgânica em superfície foram observados no plantio direto da sucessão M-F. Houve maior variação na RP entre 5 e 25 cm de profundidade, com maiores valores no plantio direto sucessão S-T e menor RP no plantio convencional sucessão M-F. A taxa respiratória dos microrganismos do solo diferiu entre as sucessões de culturas apenas na profundidade de 0-5 cm, sendo ela maior para a sucessão M-F. O solo sob plantio convencional apresentou, nas profundidades de 5-10 e 10-15 cm, maior teor de carbono vii orgânico total que o do plantio direto. O qCO2 foi maior para o solo com a sucessão M- F diferiu entre as sucessões de culturas na profundidade de 10-15 cm, tendo o solo com a sucessão M-F maior valor. As características físicas e microbiológicas do solo foram afetadas pelos sistemas de plantio e sucessões de culturas, após dez anos. O plantio direto proporcionou melhorias em algumas características físicas do solo, em relação ao plantio convencional, nos primeiros 5 cm de solo, depois de dez anos de uso. O cultivo da sucessão M-F resultou em maior porosidade no solo em superfície e em subsuperfície. As sucessões de culturas influenciaram a taxa respiratória dos microrganismos no solo apenas na menor profundidade. Maior atividade dos microrganismos no solo é observada quando empregada a sucessão milho-feijão.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de ViçosaMestrado em FitotecniaUFVBRPlantas daninhas, Alelopatia, Herbicidas e Resíduos; Fisiologia de culturas; Manejo pós-colheita deSolos - AnáliseMilho - CultivoFeijão - CultivoSoja- CultivoTrigo - CultivoPlantio diretoPlantio convencionalSoils - AnalysisCorn - CropsBeans - CropsSoy with cultivationWheat - CropsTillageConventional tillageCNPQ::CIENCIAS AGRARIAS::AGRONOMIA::FITOTECNIACaracterísticas físicas e microbiológicas do solo em sistemas de plantio e sucessões de culturasPhysical and microbiological characteristics of soil in crop succession and tillage systemsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVORIGINALtexto completo.pdfapplication/pdf692678https://locus.ufv.br//bitstream/123456789/4634/1/texto%20completo.pdf939de1debaff9a91563d20289e2b58f8MD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain95405https://locus.ufv.br//bitstream/123456789/4634/2/texto%20completo.pdf.txt05ba46982449e2dfac368da29d58bc05MD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3460https://locus.ufv.br//bitstream/123456789/4634/3/texto%20completo.pdf.jpg5ce4202ec4b739ee312df9f81da0994dMD53123456789/46342016-04-10 23:11:56.325oai:locus.ufv.br:123456789/4634Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-11T02:11:56LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
