Effect of stabilized organic amendments on biodegradability of poly-3-hydroxybutyrate, soil biological properties, and plant biomass
Original language description
Poly-3-hydroxybutyrate (P3HB) is a biodegradable polymer with potential agricultural uses. While P3HB biodegradation boosts microbial enzyme activity, it reduces plant biomass due to nutrient competition. This study explores whether co-applying nutrient-rich organic amendments like compost or digestate can mitigate these effects. A pot experiment with lettuce (Lactuca sativa) was conducted in soil amended with P3HB alone or combined with compost or digestate. Six variants were tested: Control, Compost, Compost + P3HB, Digestate, Digestate + P3HB, and P3HB alone. We assessed P3HB degradation, soil biological properties, and lettuce biomass. Results showed that P3HB alone increased dehydrogenase, urease, and respiration activities but reduced lettuce biomass (both aboveground and roots). Co-applying compost with P3HB improved enzyme activities but did not mitigate its negative impact on plant growth. However, combining digestate with P3HB alleviated the negative effects on both dry and fresh biomass and increased enzyme activity (dehydrogenase, arylsulfatase, urease) and respiration, except L-arginine-induced respiration. These findings suggest that digestate is effective in alleviating P3HB’s adverse effects on plant growth, while compost does not offer the same benefit. Organic amendments may help mitigate bioplastic biodegradation impacts in agriculture, but further research is needed to understand the underlying mechanisms.
