The Optimization of Biosilica and Humic Acid to Increase Soil Nutrient Availability and Nutrient Uptake in Rice Plant in Sandy Soil
Nutrients in sandy soil are limited due to low absorption capacity and are easily leached or evaporated. Biosilica and humic acid extracted from compost and husk ash can improve the soil structure and absorption capacity to optimize the availability and uptake of nutrients. Therefore, this research...
