“…In general, increasing soil erosion is a consequence of soil compaction linked to the use of heavy machinery and the subsequent decrease in infiltration capacity, which facilitates surface runoff and soil erosion (Filoso et al, 2015;Silva et al, 2009;Teixeira et al, 2012).…”

Soil erosion leads to land degradation and translocation of soil particles together with associated particulate organic carbon (POC) and nutrients, thereby influencing the global carbon cycle. In the present study, we estimated the contribution of POC delivered to a first-order stream from upslope sugarcane fields and a riparian forest in southeast Brazil. The results show that the amount of surface runoff and soil erosion generated in the riparian forest is significantly lower than in the upslope sugarcane field. However, the contribution of the forest to the total stream bed POC was above 70%, even though most sediments delivered to the stream originated from the upland sugarcane fields. The discrepancy between sediment and POC delivery from 2 both land uses is a consequence of the presence of preferential runoff pathways from the agricultural fields, through the buffer strips, to the stream. This disconnection between the main sources of sediment and POC to the first-order stream is a potentially important mechanism influencing the transfer of POC from upslope areas to waterways. This mechanism should be considered in order to more reliably assess fluxes of OC from upslope areas to first-order streams in landscapes where arable land is separated from streams by a semi-natural buffer zone with permanent vegetation.

“…From the different investments aiming to increase the yield of sugarcane, water-saving irrigation should be highlighted, as it may result in an increased production without expanding the agricultural area Cruz, 2002, 2008;Quintana, 2010). Thus, water-saving irrigation of sugarcane is one of the technological alternatives that pursue the increase in production in areas previously marginalized by water deficit (Teixeira et al, 2012).…”

The objective of this study was to evaluate the growth and gross yield of sugar and ethanol of first-year sugarcane with water-saving irrigation via hose-drawn traveller using a line of sprinklers. The experimental design was randomized blocks, analyzed in a split plot scheme with four replications. The factors evaluated in the plots consisted of five levels water-saving irrigation applied after planting (0, 30, 45, 60 and 75 mm). The subplots were represented by four evaluation periods (90, 170, 250 and 330 days after planting-DAP). The sugar yield and gross alcohol yield were evaluated punctually at the end of the cycle to 330 DAP. In the central lines of the subplots, the morphological characteristics relative to plant height, culm diameter, internodes length, number of sugarcane plants, number of leaves, leaf area, leaf length and leaf width, were evaluated. The gross yields of sugar and alcohol were calculated using the raw sugar value determined by technological analysis of the broth from a sample with 12 culms per experimental unit. Water-saving irrigation provides a positive effect on leaf length, leaf area, plant height and number of sugarcane plants. Water-saving irrigation of 75 mm definitely promotes an increase of 30% in gross sugar and alcohol yield.

“…O presente estudo também demonstrou claramente que a geração do escoamento superficial depende muito do estágio de desenvolvimento da cultura, o qual determina o índice da cobertura do solo. A maior interceptação da chuva pela cana-de-açúcar inicia-se na terceira fase de desenvolvimento da cultura (TEIXEIRA et al, 2012). Durante o estudo, o maior volume de escoamento foi observado quando as primeiras fases de crescimento da cana coincidiram com a estação chuvosa.…”
