Highlights

Sulphur and pollinators
Pollinators need sulphur-sufficient crops

Arable farming
Soil bacteria can dissolve calcite for healthy peanut growth
Breeding maize with high nitrification inhibitory capacity
Soil-applied glycerol can reduce nitrate leaching
Sulphur-containing signalling molecule stimulates nitrogen fixation and crop growth

Potato nutrition
Three tools to assess the phosphorus status of potato compared

Fruits, vegetables and ornamentals
Cold plasma treatment reduces micronutrient solubility of nutrient solutions
Container substrates are a source of micronutrients
Calcium can enhance lenticels breakdown in apples

Plant and soil analytics
Modified method for phosphate desorption assessment
Solar-induced chlorophyll fluorescence reflects a crop’s nitrogen status

Fertilisers
Hydrophobic coating minimizes fertiliser caking
