“…In the sequence, 1 L of sample was collected with a labelled plastic bottle. In the laboratory, both the a Brazilian sugarcane belt (Cherubin et al, 2016;Hunke et al, 2015) The objective of the present work is to experimentally evaluate sediment production and loss caused by substituting pasture with sugarcane in a Quartzarenic Neosol (Typic Quartzipsamments) soil type that is representative of the western region of the state of Sao Paulo.…”

C. Youlton, A. P. Bragion, and E. Wendland. 2016. Experimental evaluation of sediment yield in the first year after replacement of pastures by sugarcane. Cien. Inv. Agr. 43(3): 374-383. Sugarcane cultivation has expanded in south-eastern Brazil in the last decade, mainly for biofuel (ethanol) production. This expansion has occurred on land that was originally covered with pasture and used for livestock production. The purpose of this study is to experimentally determine the impact on runoff and erosion produced by replacing pasture with sugarcane. Runoff plots of 100 m 2 were established at a farm in Itirapina, Sao Paulo (SP), Brazil, on a hill with a 9% slope and sandy soil. An 18-year-old pasture and a new sugarcane plantation were studied. The degrees of runoff and erosion were determined after each rain event for the first year of cultivation. From 1,459 mm of annual rainfall, the pasture had lower runoff than the sugarcane cover (40.5 vs 56.1 mm, respectively). Soil erosion under pasture was lower than sugarcane, where the highest values were recorded at the beginning of the rainy season, just after cane planting. In the first year, the results indicate an increase in soil loss of almost 500% for sugarcane compared to pasture, from 0.58 to 2.58 Mg ha -1 year -1 under our experimental conditions. Overall, changing land cover from pasture to sugarcane increases soil erosion.

“…The lowest clay level in the microaggregates was found in the PF soils (9 %), with values which are not significant when compared with other coverage types (SF, PL, and YF), that are conservation coverages. This might be because in soils under permanent coverage, soil aggregate stability is higher (Hunke et al, 2014).…”

The transformation of primary forestlands into lands under cultivation exerts an impact on the physical and chemical properties of the soils, leading to loss of carbon from the soil. The aims of this study were (1) to estimate the impact of different land use on organic carbon stock (OC-stock) and (2) to determine the clay percentage, the dispersion factor, and bulk density with regard to soil management. Thirty soil profiles were sampled as follows: four under primary forests with 80-100 years (old growth); two under secondary wood forests with 45-50 years; eight under secondary young forests with 15-25 years; four under pasture land with 15-20 years; and 12 under continuous cultivation for > 50 years. We determined the changes in OC-stock in the soils under different land-use conditions in relation to the primary forest variant.There was a difference in the OC-stock of the continuous cultivation variant compared to the remaining land-use variants for all soil-thickness layers. The greatest loss of cultivated soil was in the 0-20 cm layer of the primary forest OC-stock. In the 50-100 cm layer, the OC-stock of the cultivated soils diminished significantly. As regards physical properties, such as clay percentage,, dispersion factor, and bulk density, we observed significant differences between the cultivated soils compared to the remaining land-use variants.

“…Surface soil compaction also leads to reduced K fs (REICHERT et al, 2009;HUNKE et al, 2015b). Our results showed K fs reductions ranging from 76 to 98% in pasture soil compared to native vegetation (Figure 4).…”

“…Sugarcane cultivation resulted in SOC losses and relies on heavy mechanization , but significant differences in soil compaction (Figures 1 and 5), as evidenced by porosity (Figure 2), SAC and SWSC ( Figure 3) and K fs (Figure 4), were not observed when compared to pasture areas. Other studies also found no differences in BD and TP (RESENDE et al, 2012) or K fs (HUNKE et al, 2015b) between long-term extensive pasture and sugarcane fields in Brazilian Cerrado, even though, both land uses had lower soil physical quality than areas with native vegetation.…”

“…With the recent shift to mechanized harvesting, intensive machinery traffic may be contributing to soil physical degradation in these areas. Studies have shown increased soil bulk density and soil strength (BAQUEIRO et al, 2012;BANGITA;RAO, 2012;, with decreases in soil porosity, aeration, aggregation, water infiltration and available water in many sugarcane fields FRANCO, 2015;HUNKE et al, 2015b).…”
