“…Perennial forages used as cover crops have great potential for C storage and directly influence SOM levels and soil aggregation (Nascente et al, 2013). There are many studies regarding soil aggregation (Castro Filho et al, 2002;Ferreira et al, 2007;Calonego and Rosolem, 2008;Canton et al, 2009;Kasper et al, 2009;. However, there is little information relating soil aggregation with cover crops and crop rotations under field conditions, especially in the Cerrado region, which has two well-defined seasons, a rainy summer and dry winter (Garcia and Rosolem, 2010).…”

Soil aggregation and the distribution of total organic carbon (toc) may be affected by soil tillage and cover crops. the objective of this study was to determine the effects of crop rotation with cover crops on soil aggregation, toc concentration in the soil aggregate fractions, and soil bulk density under a no-tillage system (NtS) and conventional tillage system (ctS, one plowing and two disking). this was a three-year study with cover crop/rice/cover crop/rice rotations in the brazilian cerrado. A randomized block experimental design with six treatments and three replications was used. the cover crops (treatments) were: fallow, Panicum maximum, Brachiaria ruziziensis, Brachiaria brizantha, and millet (Pennisetum glaucum). An additional treatment, fallow plus ctS, was included as a control. Soil samples were collected at the depths of 0.00-0.05 m, 0.05-0.10 m, and 0.10-0.20 m after the second rice harvest. the treatments under the NtS led to greater stability in the soil aggregates (ranging from 86.33 to 95.37 %) than fallow plus ctS (ranging from 74.62 to 85.94 %). fallow plus ctS showed the highest number of aggregates smaller than 2 mm. the cover crops affected soil bulk density differently, and the millet treatment in the NtS had the lowest values. the cover crops without incorporation provided the greatest accumulation of toc in the soil surface layers. the toc concentration was positively correlated with the aggregate stability index in all layers and negatively correlated with bulk density in the 0.00-0.10 m layer.

“…Besides a substitution of energy and nutrients, and a stimulation of the internal processes in soil governed by the microbial community, the application of biowaste compost in agricultural soils may positively affect soil organic-matter (SOM) content and soil-aggregate stability (Balesdent et al, 2000;Wahlen et al, 2003) and thus may reduce the potential risk of soil erosion (Barthès and Roose, 2002;Leguédois and Le Bissonais, 2004;Cantón et al, 2009). …”

Soil-quality parameters, such as soil organic matter (SOM) and plant-available nutrient contents, microbial properties, aggregate stability, and the amounts of heavy metals were carried out in arable soils of different rotation schedules applied with a total of 50 Mg dry mass ha -1 biowaste compost relative to an untreated control. This was investigated during a 10 y period from 1994 to 2004. Overall, soil-quality parameters studied appeared to be promoted by biowaste-compost application. This was evidenced for example by a remarkable increase of SOM and total N content of ≈ 15%-20% relative to the control. Subsequently, amounts of soil microbial biomass and alkaline phosphatase activity were significantly increased as well. In addition, biowaste-compost application revealed an increase of plant-available P and K contents and aggregate stability in soil. There was, however, no treatment effect for net N-mineralization rates. Moreover, in soils of maize and sugar beet rotation schedule a slight decrease was found. Heavy-metal contents of Pb and Zn were significantly increased in all compost-treated soils, whereas no significant increase of Cd and Cu contents was measured. However, the investigated amounts were far below of the limits of the German Biowaste Ordinance. It is finally recommended, that biowaste compost may sustain and improve soil quality in agriculture when N nutrition will be considered.

“…Other authors also found significant negative relationships between the aggregate stability and susceptibility to runoff (Reichert & Norton, 1994;Amezketa, Singer, & Le Bissonnais, 1996). Cantón et al (2009) showed that the stability of topsoil aggregates can be a valuable indicator of field assessed runoff of sandy loam range soils under semiarid conditions. Infiltration capacity had the highest correlation with the RWUE because of its direct influence on the runoff generation.…”

Effective use of rainfall water is a key issue in agricultural development in the arid and semi-arid regions since rainfall water is a precondition for crop production there. This study was conducted in a semi-arid agricultural region with 900 km 2 in area in Hashtroud, northwest of Iran to determine the relationship between rainwater use efficiency (RWUE) and soil properties. Winter wheat yield and soil properties were determined at 108 plots (40.41 m 2 in area) installed in thirty six dry-farming lands. RWUE of each plot obtained from the ratio of crop dry matter per unit of abstracted rainfall water volume (ARWV). ARWV was computed from deduction of the rainfall and runoff volume during a two-growth period. Runoff data for each land was obtained from field measurements at the plots under natural rainfalls. Analysis of rainfalls uniformity using four rain gauge stations data showed that spatial distributions of rainfalls were homogeneous in the area. The RWUE values in the lands were ranged from 0.35 kg m -3 to 1.49 kg m -3 with an average of 0.84 kg m -3 . Soil properties which considerably affected either the infiltration capacity or the available water controlled the RWUE in the study area. Multi-regression analysis indicated that the RWUE significantly related to silt, organic matter and lime (R 2 =0.82, p < 0.001). Maintaining crop residues and incorporating with the soil can be proper techniques and sustainable strategies to improve the soil properties and enhance the RWUE in the dry-farming lands.
