Summary
This study investigates the combined and individual effects of a controlled-release vitreous fertiliser and arbuscular mycorrhizal fungi (AMF) inoculation on phosphorus acquisition under drought stress, with a focus on phosphatase enzyme activity as a mediating mechanism. The authors, affiliated with Moroccan institutions, likely demonstrate that the dual application enhances phosphorus bioavailability and plant uptake more effectively than either treatment alone, particularly under water-deficit conditions. The work contributes to understanding how biological and slow-release mineral inputs can be integrated to improve nutrient use efficiency in drought-prone agroecosystems.
UK applicability
The study is conducted in a North African context where drought stress is a primary constraint, making direct applicability to UK field conditions limited; however, the principles of AMF–fertiliser synergies for phosphorus efficiency are broadly relevant to UK efforts to reduce phosphorus inputs and improve soil biological activity under increasingly variable rainfall.
Key measures
Phosphatase activity (µmol p-nitrophenol g⁻¹ soil h⁻¹); plant phosphorus uptake (mg P plant⁻¹); shoot and root biomass (g); drought stress indicators; mycorrhizal colonisation rate (%)
Outcomes reported
The study measured phosphatase enzyme activity, phosphorus uptake efficiency, and plant growth responses under drought conditions when controlled-release vitreous fertiliser and arbuscular mycorrhizal fungi (AMF) were applied alone or in combination. It likely reports biomass, phosphorus concentration in plant tissue, and soil enzymatic indicators as key outputs.
