Assessing Soil Phosphorus Availability and Dry Matter Production of Choy Sum (Brassica chinensis var. parachinensis) on a Tropical Acid Soil By using Rice Husk Biochar

Phosphorus (P) is an important macronutrient for plant growth and development. However, phosphorus deficiency in tropical acid soils is a common problem because soluble inorganic phosphorus is fixed by iron. The application of biochar amendments could be used to mitigate phosphorus fixation in acid...
