The mineralization of urea fertilizer mostly regulates the nitrogen dynamics in soil. A laboratory-scale study was conducted to compare two tropical soil series incubated with either liquid (LU) or granular (GU) at 0, 300, 400 500 mg/kg soils samples used experiment were Bungor and Selangor which have a sandy clay loam texture, respectively. NH4+-N, NO3−-N concentration measured for four weeks ...

The purpose of the work is to establish ecological situation in pasture phytocomplexes Don basin. objects research were plant communities on floodplain sod-meadow granular soils and sands Ilovlinsky massif Volgograd region. occurrence species Drude scale, vital state plants, projective cover vegetation, feed mass consumed determined. It established that main vegetation oppressed or a satisfacto...

Abstract We aim to enhance the stability of finite element models dynamic structural contact with multiphase granular soils which are described by advanced soil plasticity that can simulate monotonic and cyclic behaviour soils. Often, numerical oscillations cannot be avoided in these cause significantly overshoot stress, leading unrealistic discontinuities stress paths. This situation challenge...

structure of air-dry soils, pedality refers to dry aggregates. Dry aggregation is an important phase of structure Soil structural stability often decreases as the intensity of cultivation genesis in arid and semiarid soils, where it is transient, increases. The effect of three different management systems (grass, no-till, and till) on soil aggregate stability and sizes were studied in formed on...

In situ remediation technologies for contaminated soils are faced with significant technical challenges when the contaminated soil has low permeability. Popular traditional technologies are rendered ineffective due to the difficulty encountered in accessing the contaminants as well as when employed in settings where the soil contains mixed contaminants such as petroleum hydrocarbons, heavy meta...
