Nitrogen supply rate regulates microbial resource allocation for synthesis of nitrogen-acquiring enzymes. [PDF]

PLoS ONE, 2018
Although microorganisms will preferentially allocate resources to synthesis of nitrogen (N)-acquiring enzymes when soil N availability is low according to the resource allocation model for extracellular enzyme synthesis, a robust link between microbial N-

Environmental Quality Index of Urban Forest Remnants From Soil Analysis and Leaf Area Index, in Campinas – Brazil

Environmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Assessing soil quality in forest fragments is crucial for understanding ecosystem dynamics and guiding conservation strategies. This study evaluates soil properties (0–0.20m) and leaf area index (LAI) using principal component analysis (PCA) and the analytical hierarchy process (AHP) to identify key indicators of soil environmental quality ...

Relationships among Contrasting Measurements of Microbial Dynamics in Pasture and Organic Farm Soils

Applied and Environmental Soil Science, 2011
Soil bacteria exhibit short-term variations in community structure, providing an indication of anthropogenic disturbances. In this study, microbial biomass carbon (MBC), potentially mineralizable nitrogen (PMN), community level physiological profiling ...

Brassica biofumigation cover crops in US agroecosystems: A systematic review of research from 2014 to 2024

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Biofumigation with brassica cover crops (BCCs) is gaining momentum in the United States as an ecologically sound alternative to chemical pest suppression in agricultural systems. This review critically evaluates the impacts of Brassica species on soil health, weed suppression, disease mitigation, and control of plant‐parasitic nematodes (PPNs)

Legume intercropping in organic timothy seed crops

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Timothy (Phleum pratense L.) is a perennial grass widely grown for livestock feed in temperate regions of the world. It is one of the primary forage grasses grown for seed in Scandinavia due to good cold tolerance and high‐quality feed characteristics.

Enhancing soil health through no‐till, cover crops, and compost: A 5‐year field study

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract The capacity of soil management systems to conserve and promote soil health is crucial for its sustainability. While the effects of individual soil management practices on soil health receive considerable attention, their combined effects remain understudied. This paper presents the results of a 5‐year field experiment designed to evaluate the

Effects of Land Use Change and Seasonality of Precipitation on Soil Nitrogen in a Dry Tropical Forest Area in the Western Llanos of Venezuela

The Scientific World Journal, 2014
We evaluated changes of different soil nitrogen forms (total N, available ammonium and nitrate, total N in microbial biomass, and soil N mineralization) after conversion of semideciduous dry tropical forest in 5- and 18-year-old pastures (YP and OP, resp.

Trade‐offs between soil organic carbon surface gains and subsurface losses following 60 years of contrasting tillage and crop rotations

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Conservation tillage and diversified crop rotations are known to enhance soil organic carbon (SOC) storage in surface soils (0–20 cm), while their long‐term effects on subsurface SOC storage remain poorly understood. This study examined the 60+ year impacts of tillage and rotation on surface and subsurface SOC storage and aggregation at the ...

Nitrogen mineralization and phosphorus solubization due to rewetting of forest and paddy soils

Annals of Tropical Research, 2010
Rewetting of soils may cause an increase in phosphorus solubilization and nitrogen mineralization resulting in the release of bioavailable phosphates and nitrate which are vital for crop growth but are also associated with eutrophication of surface ...
