The research aims to evaluate engineered slow-release fertilizers for enhancing nutrient retention in sapric peat soils.
Conducted greenhouse experiments using biomass compost and inorganic components for SRF formulations.
Varied geometrical forms of fertilizers including pellets and cylinders were tested.
Applied fertilizers to corn and bock choy to assess nutrient uptake efficiency.
Nitrate leaching decreased significantly with cylinder formulation, from 0.14 to 0.05 mg/m2 in 2 days.
Improvement in biomass index was observed, rising from 0.32 with standard fertilizer to 1.20 with the cylinder formulation.
Engineered fertilizers showed potential for enhancing crop performance and reducing nutrient loss.
