Integrated flux and pool size analysis in plant central metabolism reveals unique roles of glycine and serine during photorespiration
Photorespiration is an essential process juxtaposed between plant carbon and nitrogen metabolism that responds to dynamic environments....

Analysis of durum wheat photosynthetic organs during grain filling reveals the ear as a water stress-tolerant organ and the peduncle as the largest pool of primary metabolites
Main conclusionThe pool of carbon- and nitrogen-rich metabolites is quantitatively relevant in non-foliar photosynthetic organs during grain filling,...

Leguminous green manure promotes N accrual in labile and persistent soil organic matter pools
Background and AimsSoil organic nitrogen (SON) provides an important source of crop N uptake. Our study aimed to better understand N incorporation in...

Plant diversity influenced gross nitrogen mineralization, microbial ammonium consumption and gross inorganic N immobilization in a grassland experiment
Gross rates of nitrogen (N) turnover inform about the total N release and consumption. We investigated how plant diversity affects gross N...

Fate of nitrogen fixed by nitrogen-fixing cyanobacteria in rice and soil during the vegetative growth period of rice
Nitrogen-fixing cyanobacteria (NFC) play an important role in maintaining the N pool of paddy fields, but few studies have been conducted on the N...

Phosphorus pool in an alfisol following three years of fallow using different types of legumes
Leguminous crops not only supply N to the soil but also phosphorus (P). The availability of P in the soil however highly depends on the P fractions,...

Pigeon pea biochar addition in tropical Arenosol under maize increases gross nitrification rate without an effect on nitrous oxide emission
Aims: To assess how biochar addition in rainfed conservation agriculture affects short-term transformation, plant uptake, retention of nitrogen (N)...

Combined inorganic nitrogen sources influence the release of extracellular compounds that drive mutualistic interactions in microalgal‒bacterial co-cultures
We investigated the role of extracellular metabolites released during mutualistic interactions in co-cultures of a microalga, Tetradesmus obliquus ...

Implication of quantifying nitrate utilization and CO2 assimilation of Brassica napus plantlets in vitro under variable ammonium/nitrate ratios
BackgroundPlantlets grown in vitro with a mixed nitrogen source utilize sucrose and CO 2 as carbon sources for growth. However, it is very difficult...

Nitrogen Sources Mitigate Cadmium Phytotoxicity Differentially by Modulating Cellular Buffers, N-assimilation, Non-protein Thiols, and Phytochelatins in Mustard (Brassica juncea L.)
This study evaluated the extent and the mechanisms underlying cadmium (Cd; 200 mg kg −1 soil) impacts and their minimization via four soil-applied...

Biological N2-fixation in grass-clover ley in response to N application in cattle slurry vs. mineral fertilizer
BackgroundThe nitrogen (N) response in grass-clover is influenced by quantity and timing of N-fertilizer, but less is known about the effect of...

Site-specific recommendations of cattle manure nitrogen and urea for silage maize
A novel decision support system (DSS) was developed to define site-specific cattle manure rates with the aim of increasing the stable pool of soil...
-
Canopy gap impacts on soil organic carbon and nutrient dynamic: a meta-analysis
Key messageThe forest canopy gaps, formed by natural or anthropogenic factors, have been found to reduce soil carbon content and increase nutrient...
