Nutrient loss pathways from grazed grasslands and the effects of decreasing inputs: experimental results for three soil types [PDF]

open access: yes
Agriculture is a main contributor of diffuse emissions of N and P to the environment. For N the main loss pathways are NH3-volatilization, leaching to ground and surface water and N-2(O) emissions.

The salt accumulation at the shifting aeolian sandy soil surface with high salinity groundwater drip irrigation in the hinterland of the Taklimakan Desert [PDF]

open access: yes, 2008
The EC analysis and water serial sampling was performed in the Tarim Desert Highway shelterbelt to explore the water and salt dynamics of the shallow aeolian sandy soil (0-30cm) under high salinity groundwater drip irrigation.

Effect of alcohol addition on the movement of petroleum hydrocarbon fuels in soil [PDF]

open access: yes, 2002
Groundwater contamination by fuel spills from aboveground and underground storage tanks has been of growing concern in recent years. This problem has been magnified by the addition of oxygenates, such as ethanol and methyl-tertiary-butyl ether (MTBE) to ...

Effect of clay amendments on nitrogen leaching and forms in a sandy soil [PDF]

open access: yes, 2010
Nitrogen (N) leaching in sandy soil decreases fertiliser use efficiency and may depress plant production. Application of high cation exchange capacity (CEC) materials (e.g.

Abundance of Rice Root Aphid Among Selected Plant Species and on Plants Grown With Different Soil-Surface Media [PDF]

open access: yes, 2018
The rice root aphid, Rhopalosiphum rufiabdominalis (Sasaki), is distributed worldwide and colonizes a wide range of plants. However, relatively little is known about the suitability of different host plants, optimal rearing techniques, and the aphid’s ...

Quantification of C and N stocks in grassland topsoils in a Dutch region dominated by dairy farming [PDF]

open access: yes
Estimates on soil organic carbon (SOC) and nitrogen (N) stocks in soils cannot be directly calculated from routine soil analyses, since these often lack measurements on soil bulk density (Bd).

Decay of escherichia coli in soil following the application of biosolids to agricultural land [PDF]

open access: yes, 2007
The decay of Escherichia coli in a sandy loam soil, amended with enhanced and conventionally treated biosolids, was investigated in a field experiment following spring and autumn applications of sewage sludge.

Soil-water characteristic curve of polypropylene fibrereinforced sandy soil

open access: yesSoils and Rocks, 2022
Fibre reinforcement is considered a good alternative for improving the geotechnical properties of soil. However, studies that investigate its behaviour, accounting for the unsaturated condition, and the hydraulic behaviour of soil mixtures with fibre, are limited.
