Resumo: | The effect of limestone may be limited to the region of its application, due to the low mobility of the products of its dissolution in the soil. Such mobility can be favored by organic acids of low molecular mass, which are released during the mineralization of plant residues. The present work aimed to evaluate the contribution of residues of three forage plant species for the mobility of the products of the dissolution of the limestone applied on the surface. Columns of soil were mounted in PVC tubes with 20 cm of height, in which Brachiaria decumbens cv. Australiano, Melinis minultiflora (molasses grass) and Stylosanthes guianensis var. vulgaris cv. Mineirão were cultivated. After 90 days of growth, limestone was applied (CaCO3 + MgCO3 p.a. with Ca:Mg molar relation of 3:1) on soil surface, according to the following treatments: T1 live plants, in other words, in activity, T2 cut plants and the material of the dried and ground aerial part (< 1 mm) applied on the surface of the soil, T3 cut plants, maintaining only the roots in the soil, T4 application of the material of the aerial part and T5- without application of the plant material, both in non-cultivated columns of soil. Columns without the application of limestone and plant material were also included as the control treatment (T6). Percolations were carried out with water equivalent to a volume of soil pores, determining the concentrations of Ca, Mg, K, inorganic anions (Cl-, CO3 2-, F-, NO3- and SO4 2-,) and organic acids (acetic, butyric, citric, malonic, oxalic and tartaric) in the leachate solutions. In the end of the experiment, the soil columns were separated into segments of 0 - 2,5, 2,5 - 5, 5 - 10, 10 - 15, 15 - 20 cm, in which the contents of Ca2+, Mg2+ and K were determined. It was observed that a higher limestone solubilization occurred in the soil in which plants were maintained alive. There was a distribution of Ca up to 10 cm of depth, regardless of the application of the plant materials. The application of limestone regardless of the application of the plant material promoted more K movement. The application of limestone and plant material of the forage plant aerial parts favored the increase in the lixiviation of Ca, Mg and K and acetic acid. |

Esta mobilidade pode ser facilitada por ácidos orgânicos de baixa massa molecular, que são liberados durante a mineralização dos resíduos vegetais. O objetivo deste trabalho foi avaliar a contribuição de resíduos vegetais de três espécies forrageiras na mobilidade dos produtos da dissolução do calcário aplicado na superfície. Foram montadas colunas de solo em tubos de PVC de 20 cm de altura, nas quais foram cultivadas Brachiaria decumbens cv. Australiano, Melinis minultiflora (capim gordura) e Stylosanthes guianensis var. vulgaris cv. Mineirão. Após 90 dias de crescimento, aplicou-se calcário (CaCO3 + MgCO3 p.a. com relação molar Ca:Mg de 3:1) na superfície do solo de acordo com os seguintes tratamentos: T1 - plantas vivas, ou seja em atividade, T2 - plantas cortadas e o material da parte aérea seco e moído (< 1 mm) aplicado na superfície do solo, T3 - plantas cortadas mantendo-se apenas as raízes no solo, T4 - aplicação do material da parte aérea e T5- sem aplicação do material vegetal, ambos, em colunas de solo não cultivadas. Incluiu-se ainda colunas sem aplicação de calcário e material vegetal como tratamento testemunha (T6). Foram realizadas percolações com água equivalente a um volume de poros do solo determinando-se as concentrações de Ca, Mg, K, ânions inorgânicos (Cl-, CO3 2-, F-, NO3- e SO4 2-,) e ácidos orgânicos (acético, butírico, cítrico, malônico, oxálico e tartárico) nas soluções lixiviadas. Ao final do experimento as colunas de solo foram separadas em seguimentos de 0 a 2,5, 2,5 a 5, 5 a 10, 10 a 15, 15 a 20 cm nos quais determinaramx se os teores de Ca2+, Mg2+ e K. Constatou-se que ocorreu maior solubilização do calcário no solo em que se mantiveram as plantas vivas. Houve distribuição do Ca até 10 cm de profundidade, independente da aplicação ou não dos materiais vegetais. A aplicação de calcário independente da aplicação do material vegetal promoveu maior movimentação do K. A aplicação do calcário e do material vegetal da parte aérea das forrageiras favoreceu maior lixiviação de Ca, Mg e K e do ácido acético. Termos de indexação: calagem superficial, resíduos vegetais, mobilidade de íons, ácidos orgânicos de baixo peso molecular, forrageiras tropicais.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de ViçosaMestrado em Solos e Nutrição de PlantasUFVBRFertilidade do solo e nutrição de plantas; Gênese, Morfologia e Classificação, Mineralogia, Química,CálcioMagnésioAcidezÁcidos orgânicosCalciumMagnesiumAcidityOrganic acidsCNPQ::CIENCIAS AGRARIAS::AGRONOMIA::CIENCIA DO SOLOMovimentação de cátions e ânions em colunas de solo influenciada pela calagem e cobertura vegetalMovement of cations and anions in columns of soil influenced by the liming and plant coverageinfo: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/pdf446339https://locus.ufv.br//bitstream/123456789/5519/1/texto%20completo.pdfc80d241c7ba0e6c36aa099cdf1473053MD51TEXTtexto completo.pdf.txttexto completo.pdf.txtExtracted texttext/plain62426https://locus.ufv.br//bitstream/123456789/5519/2/texto%20completo.pdf.txt1c8d8f93f8c8a1267e2f90ed0838b82dMD52THUMBNAILtexto completo.pdf.jpgtexto completo.pdf.jpgIM Thumbnailimage/jpeg3587https://locus.ufv.br//bitstream/123456789/5519/3/texto%20completo.pdf.jpg6b1da4a00130ebf808bb914a9652d09fMD53123456789/55192016-04-11 23:05:37.32oai:locus.ufv.br:123456789/5519Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452016-04-12T02:05:37LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
