Highlights

Arable farming
Nitrogen restrictions lead to lower protein contents in wheat and barley

Potato nutrition
Searching for nutrient profiles for early tuber yield prognoses

Plant and soil analytics
Crop and soil together determine nutrient availability
Growing degrees days indicate optimal time for nitrogen sensing in wheat
Leaf manganese concentration reflects rhizosphere levels of organic anions

Fertilisers
Rhizosphere acidification does not always increase struvite-phosphate availability
Graphene enhances crushing strength of granular MAP and DAP
Water-only extraction reflects zinc availability of granular fertilisers best

Mycorrhizae and other beneficial microorganisms
Spraying specific chitin compounds enhances mycorrhization

Silicon
Silicon promotes compensatory growth of earworm-attacked wheat
Existence of silicon transporters questioned
