Fertilizer nitrogen in soil

Agricultural and Food Science, 1961
The distribution of ammonium nitrogen and nitrate nitrogen in the soils of field trials was followed in two growing seasons. In these trials ammonium nitrate limestone and calcium nitrate were, at several rates, applied as surface dressing. It was found that not only the ammonium nitrogen but also the nitrate nitrogen applied to the surface of loam ...

Long Noncoding RNA PCALRx Interacts with Pyruvate Carboxylase to Drive Multi‐Organ Developmental Toxicity in Zebrafish Embryos Exposed to Amoxicillin

Advanced Science, EarlyView.
Embryonic amoxicillin exposure disrupts multi‐organ development in zebrafish larvae through a lncRNA–metabolic enzyme regulatory axis. PCALRx associates with pyruvate carboxylase, promotes PC protein ubiquitination, and impairs mitochondrial energy metabolism, while vitamin B1 partially restores PC‐centered metabolic function and developmental outcomes.

Replacing chemical fertilizers with organic fertilizers at equivalent nitrogen levels enhances soil nitrogen transformation rates in Northwest China’s farmlands, consequently impacting crop yields

Frontiers in Plant Science
The effectiveness of substituting organic fertilizers for chemical fertilizers in enhancing crop yield and soil quality remains uncertain. This study conducted a two-year field experiment to investigate the effects of replacing chemical fertilizer ...

Growth and yield responses in maize to split and delayed fertilizer applications on sandy soils under high rainfall regimes [PDF]

, 2010
The yield of maize (Zea mays L.) on sandy soils with high rainfall regimes is generally low due to poor nutrient use efficiency. Split and delayed basal fertilizer applications are possible strategies to improve the crop yield and reduce nutrient loss ...

A Rare De Novo Missense Mutation in IFT122 Confers a Genetic Susceptibility Factor of Idiopathic Pediatric Uveitis Via Trio‐based Whole‐Exome Sequencing

Advanced Science, EarlyView.
A rare de novo IFT122‐A773E variant is identified in idiopathic pediatric uveitis and shown to exacerbate retinal inflammation and barrier dysfunction. Mechanistically, the variant enhances IFT43 interaction, elevates calcium signaling, and activates the MEK/ERK/FRA1 axis, revealing a previously unrecognized cilia‐associated pathway that may increase ...

Multi‐Scale Bionic Structure Constructs Biomass Flame‐Retardant Thermal Insulation Foam Material

Advanced Science, EarlyView.
Inspired by mussel adhesion and hierarchical brick‐and‐mortar architectures, a cellulose‐based biomimetic foam is constructed by anchoring bentonite nanosheets onto a polydopamine‐decorated cellulose nanofiber network. The resulting foam combines low thermal conductivity with intrinsic flame retardancy and full biodegradability, presenting a ...
