Effects of vinasse application under the physical attributes of soil covered with sugarcane straw

Abstract: ABSTRACT:Areas under vinasse application have been associated to favorable physical conditions for root development, aeration, infiltration and water movement in soil profile. This study aimed to evaluate changes on physical attributes of soil under sugarcane straw after vinasse application in two sugarcane growing areas (Area 1 and Area 2) under mechanized management in the state of Paraíba, Brazil. In each area, the samples were collected in the 0-0.20, 0.20-0.40 and 0.40-0.60m layers of the soil, in 36 poin… Show more

“…A taxa de incremento estimada pela equação de regressão na camada de 0-20 cm foi de 0,0136 dag kg -1 de MOS para cada m 3 de vinhaça aplicada por hectare. Costa et al (2013) Os estudos sobre os efeitos da aplicação da vinhaça no solo são divergentes. Freitas et al (2010), em um estudo sobre fertirrigação com vinhaça, não encontraram diferença significativa na matéria orgânica nas amostras de solo de (0-20 cm) com e sem adição de vinhaça.…”

“…Diversos trabalhos tem avaliado o efeito da aplicação da vinhaça no solo em culturas, e dentre eles podemos citar o de Costa et al (2013), que estudaram o efeito da vinhaça em solo cultivado com cana e concluíram que este coproduto reduziu a densidade do solo e aumentou a matéria orgânica em uma das áreas estudadas. Já Agostinho et al (2017), não encontraram resultados satisfatórios no uso da vinhaça para melhorias de atributos microbiológico em curto período de cultivo.…”

“…There may be mentioned the Relative Nugget Effect (NE) (Trangmar, Yost, Uehara, 1985;Cambardella et al, 1994) and the Spatial Dependence Degree (SPD) (Biondi, Myers, Avery, 1994), considering, respectively, the following relations between the parameters of the semivariogram: nugget effect (C0) and sill (C0 + C1); contribution (C1) and sill (C0 + C1). These two indexes to evaluate the spatial dependence are used by many studies, for example, Barbieri et al (2013), Costa et al (2013), Kamimura et al (2013), Neves , Peluco et al (2013), Santos, H. et al (2013), , Nascimento et al (2014), Lundgren, Silva, Ferreira (2015), Rocha et al (2015).…”

“…In addition, it promotes a better oxygenation of the soil and allows the plant through its welldeveloped root system, to explore a huge volume of soil, by absorbing more nutrients and water, as well as giving the plant greater resistance to drought and other phenomena climatic conditions. The management system with vinasse provided the highest macroaggregation values to the soil, reflecting positively on macroporosity (COSTA et al, 2013) and (Silva et al, 2006a). According to Meurer (2010), the presence of macropores in the soil provides better conditions for water infiltration and better gas exchange between the soil and the atmosphere.…”

“…-0,05 m Y=1,71-6,67 x 10 -5 ** R 2 = 0,99 0,05-0,10 m Y=1,71-8,57 x 10 -5 * R 2 = 0,88 0,10-0,20 m Y=1,73-2,00 x 10 -4 * R 2 = 0,87 0,20-0,40 m Y=1,68-3,80 x 10 -5 * R 2 = 0,87 that favors flocculation and consequently the formation of stable aggregates. ForCosta et al (2013), the organic compounds that constitute the organic matter participate in connections between the individual soil particles, also acting as cementing agents of the structural units, promoting aggregation and decreasing soil bulk density.The macroaggregates are complex structures and represent a good indicator of soil physical quality, which reflects in the decrease of density values, increase in porosity, aeration and retention capacity and water infiltration in the soil(LOSS et al, 2015).Soil macroporosity at four depths at 38, 75 and 111 days after application of vinasse doses are described below(Figure 2).…”
