Sensitivity of fluvial sediment source apportionment to mixing model assumptions: A Bayesian model comparison [PDF]

, 2014
Mixing models have become increasingly common tools for apportioning fluvial sediment load to various sediment sources across catchments using a wide variety of Bayesian and frequentist modeling approaches.

Framing Effects on Public Support and Behavioral Responses to Sustainable Forest Management in South Korea

Environmental Policy and Governance, EarlyView.
ABSTRACT Despite South Korea's extensive forest coverage, which accounts for approximately 63% of its total land area, the country imports over 83% of its timber needs and has shown a gradual decline in forest carbon sequestration capacity. The Circular Forest Management Policy (CFMP) addresses these challenges through systematic forest resource ...

Nitrogen availability regulates topsoil carbon dynamics after permafrost thaw by altering microbial metabolic efficiency

Nature Communications, 2018
Input of labile carbon may accelerate the decomposition of existing soil organic matter (priming effect), with the priming intensity depending on changes in soil nitrogen availability after permafrost thaw.

Thirty years of growing cereal without P and K fertilization [PDF]

, 2008
Over thirty years a significant depletion of P and K in soil occured when the were not given in fertilizers. This caused a reduction in crop yield. An abundant P application exceeding the crop uptake very clearly prevented the yield reduction but did not

Challenges in modelling dissolved organic matter dynamics in agricultural soil using DAISY [PDF]

, 2008
Because dissolved organic matter (DOM) plays an important role is terrestrial C-,N-and P-balances and transport of these three components to aquatic environments, there is a need to include it in models.

Soil health and microbial network analysis in a wheat-maize cropping system under different wheat yields [PDF]

Frontiers of Agricultural Science and Engineering
Healthy soil is crucial for sustainable agriculture with soil microbiomes being key to soil health. However, comprehensive assessments of soil health and microbial community structures under different wheat yields have not been made.

Geophysical assessment of subsurface conditions at proposed building sites: implications for foundation failure and building collapse [PDF]

, 2018
Building collapse has been a recurrent environmental hazard in Nigeria in the last two decades. This is a corollary of inadequate foundation investigation prior to construction, poor government policies, and general lack of awareness on the importance of
