“…Therefore, the 0.10 m layer for all months showed a soil temperature fluctuation closer to the 0.05 m layer than to the 0.20 m layer. Similar results were found by Belan et al (2013) and Diniz et al (2014), who found that maximum temperatures occurred at different times. The delay from surface to deeper depths showed that the heat wave requires a certain time period to propagate in the soil because of slow heat conduction capacity through the vertical soil profile, as mentioned above.…”

“…In the same soil and location, Oliveira et al (2010) found regions closer to the soil surface showed lowest temperatures around 5 a.m. and maximum temperatures around 2 p.m. In a Latossolo Vermelho-Amarelo in the state of Espírito Santo, Brazil, Belan et al (2013) also found maximum values in the surface layer between 12 noon and 2 p.m., and Kunz et al (2002) found that the maximum soil temperature occurred around 4 p.m., which corroborates the results of this study.…”

“…The correlation between soil and air temperatures was studied by Azevedo and Galvani (2003), Carvalho et al (2009), Belan et al (2013), and Awe et al (2015), while thermal diffusivity in soil was evaluated by Amaro Filho et al (2008), Diniz et al (2014), Soares et al (2014), and Oliveira et al (2015). Several studies conducted in different soil management systems obtained a significant and inverse relationship between soil temperature and cover crop with residual or cultural biomass (Dourado-Neto et al, 1999;Silva et al, 2006).…”

Soil temperature is a physical property of great agricultural importance in the soil-plant relationship and in energy exchange with the atmosphere. This study was conducted in a degraded Cambissolo Háplico Ta Eutrófico (Cambisol; Inceptisol) in the Irecê Identity Territory, Bahia, Brazil, aiming to evaluate the hourly, daily, and monthly fluctuations of soil temperature at depth, and soil thermal diffusivity in the castor bean crop. Hourly soil temperature data from February 4, 2014, to September 30, 2015, were obtained by using thermocouple sensors (copper-constantan) horizontally installed at 0.05, 0.10, and 0.20 m depths. Soil thermal diffusivity was estimated by phase and amplitude methods. Results showed that, for most days, the soil temperature was at the level recommended for castor bean. The maximum and minimum hourly and daily soil temperatures were observed in October and July, respectively, and the maximum soil temperature values occurred at 4 p. . Soil temperature variability is low, requiring few measurement points to estimate this factor in an area. The amplitude method led to soil thermal diffusivity values compatible with results in the literature. The absence of a relationship between thermal diffusivity and soil moisture was attributed to the clay-loam soil texture, predominance of micropores, and iron oxides allowing greater approximation to the soil particles, with high thermal diffusivity even under low soil moisture conditions.

“…Com relação à característica número de plantas por hectare, todas as coberturas apresentaram resultado superior ao do sistema convencional. Isso pode ser explicado devido alguns fatores benéficos do SPD para o solo, como, maior umidade, menor variação de temperatura, melhor absorção de água, e proteção contra erosões entre outros fatores assim como relataram os autores Belan et al (2017) e Falci Dechen et al (2015, o que favoreceu o desenvolvimento e a manutenção do maior número de plantas por unidade de área nos sistemas com uso de plantas de cobertura. Mesmo com uma menor média de plantas por hectare, as médias de produtividade da soja sobre sistema convencional foi de aproximadamente 72 sacas ha -1 .…”

Avaliação de produtividade da cultura da soja semeado sobre três cultivares de Urochloa sp. em SPD e em sistema convencionalEvaluation of soybean productivity sown on three cultivars of Urochloa sp. in no-tillage system and conventional system Evaluación de productividad de la cultura de la soja semeada sobre tres cultivares de Urochloa sp. en siembra directa y en sistema convencional Samuel Dias MoreiraGraduando em Engenharia Agronômica, FCAT/UNESP, Dracena-SP, Brasil sdm.88br@hotmail.com.br Rafael Simões TomazProfessor Doutor, FCAT/UNESP, Dracena-SP, Brasil. rafaelst@dracena.unesp.br , respectivamente. Ainda, a referida cobertura foi a que mais proporcionou massa seca de resíduos totais, proporcionando maior incremento de matéria orgânica no solo. Ronaldo Cintra Lima PALAVRAS-CHAVE:Planta de cobertura, sistema de plantio, preparo do solo. SUMMARYSoybean are one of the most cultivated plants in the world being the most economically important oleaginous for national agribusiness. Associated with this crop, the no-tillage system has been used as a sustainable alternative guaranteeing benefit to the soil, mainly due to the high amount of organic material from the cover plants used in the system. Thus, the objective of this work was to evaluate the agronomic traits of soybean crop in no-tillage system comparing with the conventional system, using three grasses for straw supply. The experiment was carried out at FCAT-UNESP / Dracena in the agricultural year 2016/2017. The experimental design was a randomized block with seven replications, being the treatments, forage Ruziziensis, Piatã, Paiaguás, in addition to conventional soil preparation. It was identified that Urochloa brizantha cv. BRS Paiaguás and the conventional system provided higher grain yields in the soybean crop, with an average yield of 4368 and 4316 kg ha -1 , respectively. Also, this plant coverage was the one that provided the most dry mass of total residues, providing greater increase of organic matter in the soil.KEYWORDS: Plant cover, planting system, soil preparation. RESUMENLa soja es una de las plantas más cultivadas en el mundo siendo la oleaginosa de mayor importancia económica para el agronegocio nacional. Asociado a esa cultura, el sistema de siembra directa ha sido utilizado como alternativa sostenible garantizando beneficios al suelo, debido principalmente a la elevada cantidad de material orgánico oriundos de las plantas de cobertura utilizadas en el sistema. De esta forma, objetivamos con este trabajo evaluar las características agronómicas de la cultura de la soja en sistema de siembra directa comparando con el sistema convencional, haciendo uso de tres gramíneas para suministro de paja. El experimento fue realizado en la FCAT-UNESP / Dracena en el año agrícola 2016/2017. El delineamiento experimental fue el de bloques casualizados con siete repeticiones, siendo los tratamientos, forrajeros Ruziziensis, Piatã, Paiaguás, además de la preparación convencional del suelo. Se identificó qué cobertura Urochloa brizantha cv. BRS Paiaguás y e...

Objetivou-se avaliar a influência de diferentes quantidades de cobertura vegetal morta sobre a temperatura e a umidade do solo cultivado com milho, em Tangará da Serra, MT. O experimento foi realizado no ano de 2016, na área experimental da Universidade do Estado de Mato Grosso (UNEMAT). Analisou-se a resposta da temperatura do solo em clima tropical com estação seca no inverno (Aw segundo Köppen), em um Latossolo Vermelho distroférrico na região sudoeste do estado de Mato Grosso. Foram avaliados três tratamentos com duas repetições, sendo: sem cobertura vegetal; cobertura com 4 t ha-1 de massa seca de braquiária e cobertura com 8 t ha-1 de massa seca de braquiária. A temperatura foi monitorada através de sensores termopar do tipo K, instalados nas profundidades de 5-10 e 20-25 cm e para a umidade utilizou-se sondas de reflectometria no domínio do tempo (TDR), instalados a 30 cm de profundidade. A temperatura do solo foi reduzida com o uso da palhada de braquiária, principalmente na fase inicial de desenvolvimento da planta. As maiores variações na temperatura ocorreram na profundidade de 5-10 cm. O solo coberto com 8 t ha-1 reduziu a temperatura máxima do solo em até 2,9 ºC, além disso, a cobertura do solo proporcionou a redução da amplitude térmica no solo de 5,3 e 5,8 ºC, com 4 e 8 t ha-1 , respectivamente. A umidade do solo foi maior no cultivo de milho com cobertura de 8 t ha-1 de braquiária. Palavras-chave adicionais: amplitude térmica; reflectometria no domínio do tempo; termopar; Zea mays L.
