“…In contrast, other properties (88 %) differed between treatments, indicating that at a higher organic carbon content, the soil will be better structured, retain more moisture, with consequent reduction in PR (as in the case of TM) and develop the sugarcane root system better. This result is extremely important, since it confirms the relevance of leaving the sugarcane trash on the soil, as also reported by Mendonza et al (2000), who described the benefits of this practice. When comparing data, it was observed that 90 % of the properties were statistically significant by the F test, proving that treatment TM performed best from the point of view of soil conservation for the studied soil properties, the treatment had a direct impact on sugarcane performance, i.e., higher yields resulting in higher profit for the sugarcane growers.…”

“…It was observed that YLD (TM) was 11.4 % higher than in TR, and STD was 9.5 % higher. This behavior was due to the residues of the previous crop left in the area, increasing the levels of soil organic matter, compared with the initial analysis (August/2010), which is extremely relevant for the soil physical, chemical and biological properties as well as for sugarcane (Mendonza et al, 2000).…”

SUMMARYCurrently, sugarcane plays an important global role, particularly with a view to alternative energy sources. Thus, in a sugarcane field of the mill Vale do Paraná S/A Álcool e Açúcar, Rubineia, São Paulo State, managed under two green cane harvest systems (cane trash left on and cane trash removed from the soil), Pearson and spatial correlations between the sugarcane yield (variety RB855035 in the third cut) and soil physical and chemical properties were studied to identify the property best correlated with stalk yield and the best harvest method. For this purpose, two geostatistical grids (121 sampling points on 1.30 ha) were installed on a eutrophic Red Argisol (homogeneous slope of 0.065 m m -1 ), in 2011, to determine the properties: stalk yield and sugarcane plant population, and soil resistance to penetration, gravimetric moisture, bulk density, and carbon stock, in the layers 0-0.20 and 0.20-0.40 m. The data were analyzed by descriptive, linear correlation and geostatistical analysis. In both treatments, the property stand density was best correlated with sugarcane yield (r = 0.725 in the trash mulching treatment -TM and r = 0.769 in the trash removal treatment -TR). However, in relation to the soil properties, bulk density (0-0.20 m) was best correlated (r = 0.305 in TM, r = 0.211 in TR). Similarly, from the spatial point of view, stand density was the property that best explained the sugarcane yield. However, in the TM treatment the density (0.20-0.40 m) was 1710 the only soil property spatially correlated with stalk yield. The carbon stock in the soil of the TM was 11.5 % higher than in the TR treatment. Results of the TM treatment were best, also with regard to soil management and conservation.Index terms: sugar and ethanol production, soil management and conservation, environmental sustainability, kriging maps, Saccharum officinarum L. RESUMO: MANEJO DA PALHADA DE CANA-DE-AÇÚCAR AVALIADO PELA INTERAÇÃO DA PRODUTIVIDADE COM PROPRIEDADES DO SOLOAtualmente, a cultura da cana-de-açúcar desempenha importante papel no cenário mundial, sobretudo ao aspecto relacionado às fontes energéticas alternativas. Assim, em um talhão de cana-de-açúcar na Usina Vale do Paraná S/A Álcool e Açúcar, Rubineia, SP, manejado sob duas formas de colheita da cana crua, com palhada (COP) e sem palhada (SEP) sobre o solo, foram estudadas as correlações Pearson e espacial entre a produtividade da cana-de-açúcar (variedade RB855035, em seu terceiro corte) e as propriedades físico-químicas do solo, objetivando verificar aquele que possui a melhor correlação com essa produtividade, assim como o melhor método de colheita. Para tanto, foram instaladas duas malhas geoestatísticas (1,30 ha e 121 pontos amostrais cada) em um Argissolo Vermelho eutrófico (declive homogêneo de 0,065 m m -1 ), no ano de 2011. Os atributos avaliados foram: produtividade de colmos de cana-de-açúcar, população de plantas, resistência do solo à penetração, umidade gravimétrica, densidade e estoque de carbono do solo, nas profundidades de 0-0,20 e 0,20-0,...

“…In the same experimental site, Mendoza et al (2000) observed that in the 0.0-0.05 m layer, the maintenance of the residue on soil surface increased the levels of HU-C and FA-C; this was also corroborated by Canellas et al (2003) in areas with and without residue burning over a long period of time and with vinasse application. The MT management of sugarcane areas in the coastal tableland soils provides greater protection and/ or increased C in humic substance fractions.…”

“…In systems where the residue is not burned, an increase in P available is not expected because the sugarcane residue has a high C:P ratio and there is a relatively low amount of this element. Mendoza et al (2000) also reported greater availability of Mg 2+ and TOC in the unburned sugarcane plots. In Paraguaçu Paulista -SP, in a Dystrophic Red Latosol (Oxisol), Souza et al (2012) reported higher values of pH, TOC, Ca 2+ , Mg 2+ , K + and lower values of Al 3+ and H+Al in the area with the unburned sugarcane compared to the burned cane and native forest.…”

“…The higher amount of available P below the topsoil under CT compared with MT is explained by incorporation of crop residues and phosphate fertilizers to a greater depth with the tillage (CALEGARI et al, 2013). This explanation was presented by Mendoza et al (2000) studying in the same area and at the beginning of this experiment evaluating burnt and unburned and CT original treatments.…”

The gradual change in management practices in sugarcane (Saccharum spp.) production from burning straw to a green harvesting system, as well as the use of minimum soil tillage during field renovation, may affect soil fertility and soil organic matter (SOM) contents. The objectives of this work were to investigate the influence of sugar cane production systems on: (1) soil fertility parameters; (2) on physical carbon fractions; (3) and on humic substance fractions, in a long-term experiment, comparing two soil tillage and two residue management systems an Xanthic Udult, in the coastal tableland region of Espírito Santo State, Brazil. The treatments consisted of plots (conventional tillage (CT) or minimum tillage (MT)) and subplots (residue burned or unburned at harvesting), with five replicates The highest values of Ca 2+ + Mg 2+ and total organic carbon (TOC) were observed in the MT system in all soil layers, while high values of K + were observed in the 0.1-0.2 m layer. The CT associated with the burned residue management negatively influenced the TOC values, especially in the 0.1-0.2 and 0.2-0.4 m layers. The carbon in the humin fraction and organic matter associated with minerals were significantly different among the tillage systems; the MT showed higher values than the CT. However, there were no significant differences between the sugarcane residue management treatments. Overall, fractioning the SOM allowed for a better understanding of tillage and residue management systems effects on the soil properties. Key words: Saccharum spp. Soil tillage systems. Residue retention. ResumoA mudança gradual nas práticas de manejo da cana de açúcar (Saccharum spp.) de colheita com queima de palha para o sistema de colheita sem queima, bem como o uso de preparo mínimo do solo durante a renovação do canavial, podem afetar a fertilidade do solo e o conteúdo de matéria orgânica do solo (MOS). Os objetivos específicos foram investigar a influência de sistemas de produção de cana-deaçúcar sobre: (1) os parâmetros de fertilidade do solo; (2) sobre as frações físicas do carbono; (3) e em frações de substâncias húmicas, em um experimento de longa duração, comparando dois tipos de preparo do solo e dois sistemas de manejo da palhada em Argissolo Amarelo, na região tabuleiros costeiros do Espírito Santo, Brasil. Os tratamentos consistiram de parcelas (preparo convencional (PC)
