Land Degradation &Development, EarlyView.ABSTRACT Land use change (LUC) from paddy rice to sugarcane cultivation strongly influences soil organic carbon (SOC) stocks, with the extent and direction of change depending on residue management and time since conversion. This study aimed to (i) evaluate SOC stock changes under different residue management practices and conversion periods following ...

Microbiological Mechanisms of Sand‐Mixed Soil Improvement in Continuously Cropped Soil
Land Degradation &Development, EarlyView.ABSTRACT Sand‐mix soil is a widely adopted method for soil improvement in agricultural production. However, beyond the evident enhancement of physical structure, the mechanisms by which sand‐mix soil promotes crop root growth by influencing soil physicochemical properties and microbial communities remain insufficiently understood.

Silting of stilling basins by bedload sediments
, 2018 The main goal of this study is to define the technique to be used to assess the aggradation (by bed load) and degradation (of sediments) of the recessed as well as non-recessed stilling basins of rectangular cross section; when the hydraulic jump occurs ...

In this paper we consider a family of nested t-structures given by silting objects and construct a silting object corresponding to the intersection of aisles of these t-structures as a homotopy colimit. The dual construction for the cosilting case is given as a homotopy limit.

Wechselwirkungen zwischen universellen Lokalisierungen, Ringepimorphismen und Kippmoduln
, 2015 The aim of this thesis is to study the interaction between universal localisations, ring epimorphisms and (generalised) tilting modules. We show that these concepts are intrinsically connected and that they provide various new applications to ...

Land Degradation &Development, EarlyView.ABSTRACT Smallholder farmers in coastal Cameroon face accelerating soil degradation and climate variability. However, the adoption of sustainable agricultural practices (SAPs) remains uneven. This study examines how information behavior and motivational objectives shape SAP adoption in the Tiko municipality using a cross‐sectional survey of 122 ...

A novel approach for in situ benthic habitat characterization
Limnology and Oceanography: Methods, EarlyView.Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.

Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems
Limnology and Oceanography: Methods, EarlyView.Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...
