A Comparison of the QUECHERSER Mega-Method for Pesticide Determination in Loamy-Clayed Soil and the Effect of Organic Amendments on Pendimethalin, Oxyfluorfen, and Trifloxystrobin Soil Persistence [PDF]

Journal of Xenobiotics
The intensive use of pesticides has raised environmental concerns due to their persistence and slow degradation, posing ecotoxicological risks. Despite regulatory measures, pesticide application remains high, leading to soil and water contamination.

Soil Seed Bank Persistence Across Time and Burial Depth in Calcareous Grassland Habitats

Frontiers in Plant Science, 2022
Seed persistence in the soil is crucial for population dynamics. Interspecific differences in soil seed mortality could be a mechanism that may stimulate species coexistence in herbaceous plant communities.

Land-use induced soil carbon stabilization at the expense of rock derived nutrients: insights from pristine Andean soils

Scientific Reports, 2023
Soils contain significantly more carbon than the atmosphere, hence we should understand how best to stabilize it. Unfortunately, the role of human interventions on soil organic carbon (SOC) persistence in the Anthropocene remains vague, lacking adequate ...

Arctic Soil Governs Whether Climate Change Drives Global Losses or Gains in Soil Carbon [PDF]

, 2019
Key uncertainties in terrestrial carbon cycle projections revolve around the timing, direction, and magnitude of the carbon cycle feedback to climate change. This is especially true in carbon-rich Arctic ecosystems, where permafrost soils contain roughly

Persistence of D.D.T. in the Soil [PDF]

Nature, 1948
THE note by M. S. Smith1 concerning the persistence of D.D.T. and ‘Gammexane' in soil is in conformity with the results of experiments carried out in Australia on the use of D.D.T. as a control of the scarab Aphodius howitti Hope, the larvae of which infest pastures on the tablelands of south-eastern Australia.
