“…2a). The presence of crop residues on the soil surface could have enhanced rainfall water infiltration and decreased evapotranspiration in US treatments, while surface sealing of the topsoil layer could have impaired water infiltration in DS treatments (Lanzanova et al, 2010).…”

A B S T R A C TAgriculture can be either a source or sink of atmospheric CO 2 depending on soil management. The application of swine slurry in conventional tilled soils could enhance soil CO 2 emission depleting soil organic C stocks. However, the use of recalcitrant C-rich organic fertilizers in no-till soils can offset soil CO 2 emission promoting soil C sequestration. This hypothesis was tested by evaluating short-term CO 2 -C emissions from a Rhodic Nitisol under contrasting soil disturbance levels (disturbed (DS) and undisturbed soil (US)) top-dressed with mineral or organic fertilizers (urea (UR), raw swine slurry (RS), anaerobically digested swine slurry (ADS), and composted swine slurry (CS)). Soil CO 2 emission was evaluated for 64 days using static chambers where gas samples were collected and analysed by photoacoustic infrared spectroscopy. Soil water-filled pore space (WFPS), temperature and meteorological data were concomitantly registered and a first-order exponential decay model was used to assess the decomposition of organic fertilizers and CO 2 emissions induced by soil disturbance. Soil CO 2 -C emission was correlated with soil temperature, while limiting soil aeration impaired CO 2 -C efflux when WFPS >0.6 cm 3 cm À3 . Disturbance increased soil CO 2 -C efflux (36.3 AE 2.2 kg CO 2 -C ha À1 day À1 ) in relation to US (33.3 AE 1.6 kg CO 2 -C ha À1 day À1 ). Extra labile C input through RS amendment induced an increased soil CO 2 -C efflux for a longer period (t 1/2 = 16.9 and 9.6 days in DS and US treatments, respectively), resulting in higher CO 2 -C emissions than soil amended with other fertilizers. The recalcitrant C input by ADS and CS had limited effect on soil CO 2 -C emissions. CS presented a genuine potential for substantial soil organic C accumulation while offsetting increased CO 2 -C emissions in comparison to RS amended soils.

“…For the MT and NT treatments, the logarithmic model better fitted the data (Figure 1b), indicating that these accumulated losses tended to stabilize over time in these treatments. Water erosion evaluated over 17 years in an Argissolo Vermelho (Acrisol) with sandy texture decreased three years after the adoption of the no-tillage system (Lanzanova et al, 2013). The linear model was fitted to the accumulated losses of water according to time (Figures 1c and 1d) for all treatments, with the angular coefficients being 534, 338, 209, and 119 mm yr -1 for BS, CT, MT, and NT, respectively.…”

Water erosion, the main factor in soil degradation, is strongly influenced by soil cover and management. The objective of this study was to determine soil and water losses under natural rainfall conditions from 1993 to 2012 in the southern Santa Catarina Plateau, Brazil, in 3.5 × 22.1 m plots with crops in rotation to study the following management treatments: conventional tillage (CT), minimum tillage (MT), and no-tillage (NT), and a treatment with bare soil (BS). The soil cover remaining after tillage was negatively affected by the increase in soil tillage intensity. Soil losses were strongly affected by the management system, while water losses were less affected. Soil losses were 85.29, 6.41, 2.00, and 0.82 Mg ha -1 yr -1 in the BS, CT, MT, and NT treatments, respectively, while water losses were 38, 24, 15, and 9 % of the rainfall, respectively, in the annual mean. Soil losses in spring/summer were similar to those of autumn/winter in the CT, MT, and NT treatments, while water losses were influenced by the time of year in all soil management systems. The accumulated soil losses in the MT and NT treatments tended to stabilize over the period evaluated, whereas they increased an average of 88.12 Mg ha -1 yr -1 in the BS and 7.23 Mg ha -1 yr -1 in the CT treatments. The accumulated water losses had a linear response, with positive angular coefficients for all treatments. The relationship between annual soil and water loss data was significant in the BS treatment; in the CT, MT, and NT treatments, this relation was not significant.

“…The SFS treatment promoted the lowest PR index in LVw due to the lower number of agricultural operations. However, maintaining fallow land during sugarcane fallow-period is not a recommended management practice, since soil without vegetation cover is more susceptible to erosion (Lanzanova et al, 2013), and it may present a reduction in aggregation due to lower accumulation of OM (Garcia et al, 2013).…”

The objective this work was to evaluate the organic matter content and the physical attributes of two Red Latosols 30 months after use in the sugarcane fallow-period. The long-term experiment was conducted on two Red Latosols. The design was in blocks, with four treatments and five replications. The treatments were soybean/millet/soybean; soybean/sunn hemp/soybean; soybean/fallow/soybean and soybean. At 30 months after the fallow-period the layers of 0.00-0.10 and 0.10-0.20 m were sampled for the determination of the weighted average diameter of the aggregates; and the layers 0.00-0.10; 0.10-0.20; 0.20-0.40 and 0.40-0.60 m for the determination of organic matter, aggregate stability index, soil density, porosity and resistance to penetration. The uses promoted an increase in organic matter and porosity, a reduction in the aggregation of soils evaluated 30 months after the fallow-period of the cane in relation to that determined after the fallow-period. At 30 months, the resistance to penetration of acric Red Latosol was different among the uses, and soybean/fallow/soybean yielded the lowest value in relation to the soybean and soybean/sunn hemp/soybean use. Uses had no effect on attributes assessed after 30 months.
