Effect of phosphorus levels on yield, nutrient uptake and phosphorus utilisation efficiency in rice (Oryza sativa L.) using ³²P radiotracer technique under pot culture
Phosphorus (P) is a primary limiting macronutrient in tropical and subtropical rice production. While total soil P may be high, over 50 % of global agricultural soils suffer from low bioavailable orthophosphate due to strong chemical fixation with aluminium (Al) and iron (Fe) oxides in acidic soils, or calcium (Ca) in...
