Sentence examples for breakdown of soil from inspiring English sources

The figure directly shows that the drying wetting cycles cause the breakdown of soil aggregates gradually.

Therefore, there is necessity to further our understanding on the impact of the drying wetting cycles and initial water content on the breakdown of soil aggregates.

In most agricultural systems, the raindrop-induced breakdown of soil aggregates is the initial process of surface soil erosion and redistribution of soil organic matter.

Although groundwater levels are kept high to limit breakdown of soil organic matter, the high availability of N and P from unavoidable peat mineralization offers the possibility to drastically reduce fertilizer inputs, which will directly reduce nutrient losses to the environment.

Most of the elements required for plant nutrition come from the chemical breakdown of soil minerals.

He and his colleagues originally set out to investigate the relationship between precipitation and chemical weathering, or the breakdown of soils and rocks.

After the breakdown of the soil aggregates by wet sieving, the variations of MWD and GMD with the initial water content are showed in Fig. 8a.

Chemical, physical, and biological alteration and breakdown caused mineralization of soil organic matter (SOC) and increased CO2 emission (van Gestel et al. 1991), which accounted for about 60% of total greenhouse impacts (Rastogi et al. 2002).

The cumulative CO2 emitted from bulk soil samples and different aggregate sizes fractions from five slope positions in a landscape was examined in a 128-d incubation study to estimate how the breakdown and dispersion of soil aggregates by erosion affect C loss to the atmosphere via CO2 emission.

The results demonstrated that organic soil management can substantially improve soil structural condition, especially in terms of organic matter level, soil aggregate stability (ability of soil to resist breakdown by forces associated with cultivations) and soil pore characteristics, but that the effects might be both scale and time-dependent.
