Nitrogen Turnover on Organic and Conventional Mixed Farms [PDF]

, 1995
Separate focus on crop fertilization or feeding practices inadequately describes nitrogen (N) loss from mixed dairy farms because of (1) interaction between animal and crop production and between the production system and the manager, and (2 ...

Alteration of soil carbon and nitrogen pools and enzyme activities as affected by increased soil coarseness [PDF]

Biogeosciences, 2017
Soil coarseness decreases ecosystem productivity, ecosystem carbon (C) and nitrogen (N) stocks, and soil nutrient contents in sandy grasslands subjected to desertification. To gain insight into changes in soil C and N pools, microbial biomass, and enzyme

Utilization of organic nutrients by coccolithophores [PDF]

Marine Ecology Progress Series, 2010
Coccolithophores play a prominent role in the marine, and by extension the global, car- bon cycle. The ability of coccolithophores to thrive on organic nutrients is assumed to be a key rea- son for their ecological success, as Emiliania huxleyi grows well on a variety of organic nutrients.

Review of the Presence and Phage-Mediated Transfer of ARGs in Biofilms

Microorganisms
The widespread use of antibiotics has led to the emergence of a large number of drug-resistant bacteria, accelerating the dissemination and spread of antibiotic resistance genes (ARGs) in the environment. Bacterial biofilms, serving as reservoirs of ARGs,

Pyramiding of Low-Nitrogen-Responsive QTL Clusters Enhances Yield and Nutrient-Use Efficiency in Barley

Agriculture
Given that nitrogen (N) is a major limiting factor for global crop production, improving low-nitrogen (LN) tolerance in barley is essential for sustaining yields worldwide.

Transcriptome and weighted gene co-enrichment analysis revealed modules and candidate genes associated with barley response to low potassium stress

Frontiers in Plant Science
Potassium deficiency is one of the key factors affecting crop yields. This study investigated the effects of low potassium stress on the growth of three barley varieties from physiological and biochemical indicators, transcriptomics and weighted gene co ...
