Resumo: | The existence of spatial variability in soil properties influences the production of forage. The study aimed to determine the spatial distribution of soil chemical properties relating it to the production and the preference of grazing animals in pasture Urochloa brizantha cv. Marandu (Syn. Brachiaria brizantha) under continuous stocking. To characterize the pasture area, were carried out measurements of 108 points with distribution in irregular mesh with samplings to determine the chemical properties (pH, organic matter, P, K, Ca, Mg, Al, H + Al) and soil density , forage production, sward height, SPAD index and intensity of grazing in the water period of 2012. The normality test was made, followed by a descriptive analysis of the data analysis and geostatistics. Although the present condition of operation, it was observed that the chemical characteristics of the soil and soil density, as well as production and pasture height space dependence, presented same pattern of response, inferring that such responses are inter-relation. The factors that cause variability in soil characteristics, also interfere in influencing pasture related in part in grazing animal. Chemical soil attributes, density, dry mass, height, and grazing intensity, set the exponential model. The estimation of the spatial variability of soil attributes together with assessment of the availability of pasture, and animal grazing preference points, are important tools for establishing criteria for use and differentiated management within the same pasture area, in order to prevent degradation of the soil and grass. |

O trabalho teve como objetivo determinar a distribuição espacial das propriedades químicas do solo relacionando-a com a produção e a preferência de forragem por animais em pastejo de Urochloa brizantha cv. Marandu (Syn. Brachiaria brizantha) sob lotação contínua. Para caracterização da área de pastagem, foram realizadas medições de 108 pontos com distribuição em malha irregular, com coletas de solo para determinação dos atributos químicos (pH, matéria orgânica, P, K, Ca, Mg, Al, H+Al) e densidade do solo, produção de forragem, altura do dossel forrageiro, índice SPAD e intensidade de pastejo, no período das águas de 2012. Realizou-se o teste de normalidade, seguido de análise descritiva dos dados e análise geoestatística. As características químicas e densidade do solo, bem como a produção e altura do pasto, apresentaram dependência espacial, com mesmo padrão de resposta, inferindo que tais respostas são interrelacionadas. Os fatores que causam a variabilidade nas características do solo também interferem nas relacionadas ao pasto influenciando em parte no pastejo animal. Os atributos químicos do solo, densidade, massa seca, altura e intensidade de pastejo, ajustaram-se ao modelo exponencial. A estimativa da variabilidade espacial dos atributos do solo juntamente com avaliação da disponibilidade do pasto e os pontos de preferência do pastejo animal são ferramentas importantes para estabelecer critérios de uso e manejo diferenciado dentro de uma mesma área de pastagem, na perspectiva de evitar degradação do solo e do pasto.Universidade Federal de Viçosa - UFV2016-10-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/54610.13083/reveng.v24i4.602Engineering in Agriculture; Vol. 24 No. 4 (2016); 338-349Revista Engenharia na Agricultura - REVENG; v. 24 n. 4 (2016); 338-3492175-68131414-398410.13083/reveng.v24i4reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/546/376Alencar, Nayara MartinsMelo, Jonahtan ChavesSantos, Antonio Clementino dosCunha, Odislei Fagner RibeiroPaula Neto, Joaquim José deinfo:eu-repo/semantics/openAccess2023-01-19T13:31:24Zoai:ojs.periodicos.ufv.br:article/546Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:31:24Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false |
