Summary
This 2024 field study examined how reducing inorganic fertiliser inputs whilst applying biochar amendment affected soil carbon dynamics, microbial communities, and enzymatic activity in a southeast Chinese jasmine garden. The research suggests that combined fertiliser reduction and biochar incorporation may enhance soil carbon stabilisation through mineral association and support increased microbial and enzymatic functioning, potentially indicating improved soil health and carbon sequestration. The findings contribute to understanding low-input horticulture practices in subtropical environments.
UK applicability
Results from a subtropical, ornamental horticulture system in high-rainfall southeast China may have limited direct applicability to UK temperate vegetable or soft-fruit systems, though biochar's role in carbon stabilisation warrants evaluation in UK soil conditions. UK horticultural adoption would require parallel trials accounting for cooler temperatures, different soil mineralogy, and native microbial communities.
Key measures
Soil mineral-associated organic carbon (MAOC), bacterial activity markers, enzyme activity (as suggested by title), fertiliser application rates
Outcomes reported
The study assessed soil mineral-associated organic carbon content, bacterial activity, and enzyme activity under different fertiliser and biochar amendment regimes in a jasmine garden system.
