Synergistic role of silicon and rapeseed cake in enhancing phosphorus dynamics and nutrient biofortification of rice in acidic soils.

Key Points

• The research aims to explore how silicon and rapeseed cake enhance phosphorus dynamics and nutrient biofortification in rice grown in acidic soils.
• Conducted a short-term field study
• Replaced 30% of urea fertilizer with rapeseed cake
• Applied silicon and rapeseed cake together in acidic paddy soil
• Rapeseed cake improved soil nutrient sustainability
• Combined application of silicon and rapeseed cake enhanced grain nutrient biofortification
