Soil preservation is crucial for maintaining agricultural productivity amid global population growth and food demand. However, industrialization and heavy metal contamination have limited sustainable farming practices. Phosphogypsum (PG), a by-product of phosphate fertilizer production, poses environmental risks due to heavy metal content and accumulation. This study investigates the safe reuse of PG in soils through surface modification with polymeric coatings (PEG, PVP and DX) to reduce heavy metal leaching. PG samples coated at mass ratios (1:1, 1:2, 1:3) were analyzed by XRF, FT-IR, zeta potential and spectrophotometric methods, while morphology and particle size were examined via TEM and DLS. Results show that polymer coatings improve the chemical stability of PG and limit heavy metal mobility, enhancing its suitability for agricultural use. Coated samples exhibit 20, 30, 19, 10 and 10% releases of Cr2+, Mn2+ Cu2+, Hg+ and Pb2+ heavy metal cations respectively which were significantly lower than heavy metals release measured in bare PG. This approach offers an effective PG management strategy, promoting soil protection and environmental sustainability with further studies needed on economic feasibility for large-scale applications.
