Perspectives of High‐Resolution Mass Spectrometry in Soil Science

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Soil biogeochemical research requires specific, sensitive, and accurate methods to identify and quantify organic molecules in order to trace biochemical processes and assess element cycling in complex, heterogenous systems. High‐resolution mass spectrometry (HRMS) has evolved into a transformative tool for unraveling the complex chemical ...

Chloroform fumigation and the release of soil nitrogen: a rapid direct extraction method to measure microbial biomass nitrogen in soil

, 1985
A new “direct extraction” method for measuring soil microbial biomass nitrogen (biomass N) is described. The new method (fumigation-extraction) is based on CHC13 fumigation, followed by immediate extraction with 0.5 M K2SO4 and measurement of total N ...

Phytochemical profiling and insecticidal activity of Moricandia sinaica across growth stages: experimental and molecular docking insights

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Stored food products are highly vulnerable to infestation by insects and mites, resulting in significant postharvest losses worldwide. Plant‐derived bioactive compounds represent promising eco‐friendly alternatives to synthetic pesticides.

Evaluation of Wireless Phosphine Sensors for Monitoring Fumigation Gas in Wheat Stored in Farm Bins

Insects, 2019
Fumigation of grain bins with phosphine tablets is one method of insect control for stored products. Monitoring the concentration of the toxic gas at many locations over several days for a given structure or container can be challenging. In this study, a

The effects of biocidal treatments on metabolism in soil .1. Fumigation with chloroform

, 1976
This series of five papers is a study of how biocidal treatments influence metabolism in soil, directed particularly towards the flush of decomposition caused by fumigation, and designed to see if the size of this flush can be used as a measure of the ...

Long‐Term Nitrogen Addition Weakens the Linkage Between Phosphorus Cycling Gene Abundance and Phosphatase Activity Through Soil Acidification in a Larix gmelinii Plantation

Land Degradation &Development, EarlyView.
ABSTRACT Anthropogenic nitrogen (N) enrichment propels global forest ecosystems toward phosphorus (P) limitation, theoretically triggering the upregulation of microbial P‐acquisition capacity to maintain stoichiometric balance. However, the extent to which N addition regulates this adaptive capacity remains uncertain.

Optimized Fertilization Balances Microbial Carbon and Nitrogen Use Efficiency: Evidence From Microbial Communities

Land Degradation &Development, EarlyView.
ABSTRACT Optimized fertilization involving reduced mineral N input and organic substitution can alter resource stoichiometry, microbial carbon use efficiency (CUE) and nitrogen use efficiency (NUE). However, how fertilization‐induced resource imbalance reshapes microbial community to regulate CUE and NUE remains unclear. We conducted a field experiment
