Resumo: | The soil temperature is related with the processes of soil-plant interaction, particularly seed germination, development and activity of the roots absorbing water and nutritious from the soil, microorganisms activity, gases and solute diffusion, disease development, chemical reactions speed in the soil. Due to the importance of soil temperature for the vegetables, this study aimed at verifying the temperature in soil profile at different depths in nude soil and with two mulching densities. The experiment was carried out in the Estação Experimental Agrometeorológica (Agrometeorological Experimental Station) of Universidade Estadual do Oeste do Paraná – Campus of Cascavel. Thermopares type (K) were installed in soil profile, at depths of 2, 5, 10, 20 and 40 cm, connected to a data acquisition equipment, programmed to effectuate one reading per second and to store arithmetic averages every five minutes, under two black oat mulching densities (4,000 and 8,000 kg.ha-1). Results showed that the larger the mulching density of the soil, the lesser is its profile temperature variation. Soil temperature at 40-cm depth is practically stable during all day and night, for both mulching densities of the soil and for nude soil. |

Devido à importância da temperatura do solo para os vegetais, objetivou-se estudar a temperatura no perfil do solo a diferentes profundidades em solo nu e com duas densidades de cobertura morta. O experimento foi instalado e conduzido na Estação Experimental Agrometeorológica da Universidade Estadual do Oeste do Paraná - Campus de Cascavel. Foram instalados termopares tipo (K) em perfil do solo, nas profundidades de 2, 5, 10, 20 e 40 cm, conectados a um equipamento de aquisição de dados programado para realizar uma leitura por segundo e armazenar médias aritméticas a cada cinco minutos, sob duas densidades de cobertura morta (4000 e 8000 kg.ha-1) de aveia preta. Pelos resultados obtidos, concluiu-se que quanto maior a densidade de cobertura morta sobre o solo, menor é a variação da temperatura no seu perfil. A temperatura do solo na profundidade de 40 cm é praticamente estável durante o decorrer das 24 horas do dia, nas duas situações de cobertura morta do solo e em solo nu.Universidade Estadual de Maringá2008-04-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/212710.4025/actasciagron.v27i1.2127Acta Scientiarum.
