“…The local climate leaves a short time interval for the corn crop cycle. Thus, it is fair to consider that much of the soil physical properties deterioration presented in C4 and C10 treatments, when they were compared to DF and C1 treatments, are coming from the intensive machinery traffic (especially from soil preparation for planting) under soil excessive moisture conditions (Severiano et al, 2008;Ng Cheong et al, 2009). …”

“…This traffic when performed under inappropriate moisture conditions can accelerate a series of soil physical properties exchanges (Hamza and Anderson, 2005;Severiano et al, 2008;Sant'anna et al, 2009), causing deterioration of several soil quality indicators. The most classical result of these changes is the appearance of compacted layers in the root growth influence zone (Ng Cheong et al, 2009), that very commonly cause decreasing agronomic productivity over time (Bronick and Lal, 2005).…”

A B S T R A C TThe intensive machinery traffic is an important feature of industrial agroecosystems. This traffic when performed under inappropriate moisture conditions can accelerate a series of soil physical properties exchanges, causing deterioration of several soil quality indicators. Intensive agricultural activity is advancing rapidly in western Sergipe State and northeastern Bahia State (Brazilian semi-arid regions), mainly on soils developed from limestone substrata. This study characterized the soils and investigated the effect of increasing periods of corn crops and other land use types on soil attributes of calcareous soils from Western Sergipe State, with emphasis on physical attributes, particulate organic matter, and total organic C. Five combinations with five replicates of land use were selected: dry forest (DF); corn crop (first, fourth and tenth year -C1, C4 and C10) after forest removal; and intensive pasture (IP). The study areas were dominated by soils with vertic properties. Almost all the chemical and physical attributes showed a lesser quality in IP sites compared with the other treatments. The differences among the DF sites and corn crop sites were smaller. When compared the land use time of corn crop treatments (with DF as zero time), tenuously, some attributes formed two groups, where DF and C1 treatments were separated from C4 and C10 treatments. Regarding the comparison of all treatments, the non-metric multidimensional scaling technique explained 94% of the variability (in two axis) of the 19 attributes analyzed, being the major part represented by axis 1 (79%). The IP sites had the greatest soil physical degradation index among all groups. The C1 sites had significant contrast compared with the DF sites. The C4 sites showed a loss of quality in many soil physical properties compared with C1 sites. There were no differences between the C4 and C10 sites. This shows that in order to achieve a near steady state a greater number of cultivation years is required.

“…The mechanized green harvesting of sugarcane can also increase the soil organic matter content and lead to more honmogenous micro and macropore distribution, improving aeration and water infiltration and retention, with an altogether positive effect on the soil physical and chemical quality (Canellas et al, 2003;Ng Cheong et al, 2009). Furthermore, the soil structure is improved and bulk density reduced, which means that more of the soil can be exploited by the roots (Passarin et al, 2007).…”

“…Therefore, burning the plantation causes great harm to soil and air quality (Allen et al, 2004). When cane is harvested green however, despite the increment in the layer of soil organic matter and improved physical and chemical soil quality (Canellas et al, 2003), the use of machinery under unsuitable humidity conditions can result in a series of changes in the soil physical properties (Severiano et al, 2008), including compaction (Ng Cheong et al, 2009).…”

SUMMARYThis study had the purpose of evaluating the effects of two management types of sugarcane: harvesting of burnt cane (BCH) and mechanized harvesting of unburnt green cane (MCH), on some soil physical properties of a dystrophic Rhodic Haplustox. The data were then compared with results for the same soil type under native forest. A completely randomized design was used, with three treatments and 20 replications. The following characteristics were determined: organic matter, aggregate stability, soil bulk density, and porosity at depths of 0-0.20 m and soil penetration resistance. After 15 years of cultivation, there were some alterations in the soil under cane burnt before harvesting, evidenced by a drop in the weighted average diameter of stable aggregates in water and increased soil bulk density. Significant changes were also detected in total porosity and pore distribution under both harvesting systems. Critical values for penetration resistance were observed in the area under mechanized sugar cane harvesting, with a value of 4.5 MPa in the 40-55 cm layer. This value is considered high and could indicate compaction and restriction of root growth. Soil properties under the green cane (unburned) management system were closest to those of the soil under native forest.Index terms: Saccharum officinarum, soil bulk density, porosity, soil penetration resistance, soil aggregate stability.(

Probabilistic soil mapping by Bayesian inference to assess suitability for derocking in northwest Syria

Land reclamation by rock removal has wide potential in areas with shallow or rocky soils. In northwest Syria, this practice is hindered in its implementation by a lack of physical soil suitability data, principally soil rockiness and soil depth to hard rock. These soil properties were surveyed in a limited study area, resulting in a hard-boundary thematic soil map (64-94% accuracy per property). Bayesian inference is proposed as a low-cost upscaling method that yields a set of pixel-based probability maps, providing improved input for spatial decision support models. Whereas the achieved spatial upscaling (from 2510 to 19 100 ha) outweighed the decrease in overall accuracy (down to 26-57%), probability maps require dedicated validation and manipulation procedures. This research contributes to methods for the creation, validation and interpretation of probabilistic soil property maps for quantitative land evaluation. First, we evaluated three postprocessing and validation methods for probabilistic soil property maps, identifying the use of 'prediction rates' as the best approach in a spatial planning context. Next, we demonstrated how the maps can support decision-making for land management activities by simulating the expected losses and gains from interventions, in a decision-theoretic approach. Based on the simulations, the investments in largescale derocking projects in northwest Syria will pay off in terms of increased agricultural productivity in less than 10 years.
