introduction: soil aggregate stability is a key factor in soil resistivity to mechanical stresses, including the impacts of rainfall and surface runoff, and thus to water erosion (canasveras et al., 2010). various indicators have been proposed to characterize and quantify soil aggregate stability, for example percentage of water-stable aggregates (wsa), mean weight diameter (mwd), geometric mea...

The principle of enzyme kinetics suggests that the temperature sensitivity (Q10) of soil organic matter (SOM) decomposition is inversely related to organic carbon (C) quality, i.e., the C quality-temperature (CQT) hypothesis. We tested this hypothesis by performing laboratory incubation experiments with bulk soil, macroaggregates (MA, 250-2000 μm), microaggregates (MI, 53-250 μm), and mineral f...

The subject of this paper is the evaluation use waste material, which native soil. On example base ground taken from village Lipie (Podkarpackie voivodeship), soil-aggregate mixtures were prepared with a different degree addition natural aggregate. study analysed quantitative and qualitative parameters assessed their physical mechanical properties to determine suitability for construction nfras...

Balanced and integrated use of organic and inorganic fertilizers may enhance the accumulation of soil organic matter and improves soil physical properties. A field experiment having randomized complete block design with four replications was conducted for 36 years at Punjab Agricultural University (PAU), Ludhiana, India to assess the effects of inorganic fertilizers and farmyard manure (FYM) on...

The formation and stabilization of soil aggregates play a key role in soil functions. To date, few studies have been performed on the variation of soil aggregation with increasing soil weathering degree. Here, soil aggregation and its influencing factors along the weathering gradient were investigated. Six typical zonal soils (derived from similar parent materials) were sampled from temperate t...

Despite the importance of arbuscular mycorrhizae to the functioning of terrestrial ecosystems (e.g. nutrient uptake, soil aggregation), and the increasing evidence of global warming, responses of arbuscular mycorrhizal fungi (AMF) to climate warming are poorly understood. In a field experiment using infrared heaters, we found effects of warming on AMF after one growing season in an annual grass...

Cement stabilization improves physical and mechanical properties of geotechnical materials. However, numerous combinations materials cement hinder to establish a pattern behavior cement-stabilized Thus, this study aims evaluate the soil-aggregate-cement mixtures (SAC) using high early-strength (HE), contribute dosage aspects ascertain their recommendation as base and/or subbase layers in heavy ...

reported resistance values of 2,8 to 3,2 MPa for tillage pans in A long term trial to study the sustainability of a vertisol under continuous spgarcane monocropping was commenced in 1939 at the Experiment Station of the South African Sugar Association. The design of the trial consists of four replications of two main plots, each split into four sub-plots. The treatments comprise various combina...
