Leaf and must nitrogen content two complementary indicators of grapevine nitrogen status
Grapevine nitrogen status was assessed by nitrogen content in leaf blade and petiole at veraison, in must at harvest and in pruned wood in December.

A bias‐free photoelectrochemical (PEC) upcycling system integrating bi‐functional nickel‐iron‐phosphorus (Ni‐Fe‐P) catalysts with organic semiconductor (OS)‐based dual photoelectrodes is reported. The system enables simultaneous solar‐driven conversion of nitrate to ammonia and glycerol to formic acid with high efficiency and stability.

Effect of Sulphur Fertilisation on Lycopene Content and Colour of Tomato Fruits
The effects of different sulphur (S) fertilisers (ammonium, sodium, potassium and calcium sulphates) in combination with nitrogen (N) on plant growth, yield and quality of fruits were investigated in two dwarf cultivars Proton and Šejk. Single N, applied

What will long-term experiments deliver? Key results of 12 experiments on different continents. [PDF]
Twelve long-term experiments have been used to describe the main management effects of organic farming systems. The experiments were mostly used to compare various types of organic and conventional cropping systems, or to study fertilisation effects ...

How to enhance crop production and nitrogen fluxes? A result-oriented scheme to evaluate best agri-environmental measures in Veneto Region, Italy [PDF]
The cost-effectiveness of adopting agri-environmental measures (AEMs) in Europe, which combine agricultural productions with reduced N losses, is debated due to poorly targeted site-specific funding that is allocated regardless of local variability.

A Roadmap for Plasma‐Enabled Electrocatalysis in Urea Production
A modular plasma—electrochemical platform enables fully electrified urea synthesis from air and CO2 under ambient conditions. This Review integrates plasma oxidation, C─N coupling electrolysis, mechanistic insights, and techno‐economic metrics into a roadmap for scalable, distributed, and renewable fertilizer production.

Analysis of the Physico-Chemical Properties of Bean Seeds after Three Years of Digestate Use
Taking into consideration its physico-chemical properties, digestate should be used primarily as a fertiliser. The possible ways of using digestate as a fertiliser in agriculture were identified, and digestate collected from an agricultural biogas plant ...

Self-fertilisation in Mollusca [PDF]
As the question of self-fertilisation in the more highly organised invertebrates is of considerable importance from the genetic point of view, I would like to direct the attention of readers of NATURE to a publication (Acta Soc. pro Fauna et Flora Fennica, vol. 40, No. 2, 1915), a copy of which I have just received from the author, Dr. A. Luther.

Impact of cropping system on mycorrhiza [PDF]
The impact of cropping system on field communities of mycorrhizal fungi was studied utilising a long-term experiment on a loamy soil. Two contrasting crop rotations each with two fertilisation regimes were compared. The conventional crop rotation (barley-
