摘要

Aims

To investigate the effect of biochar in different fertilizer combinations on potato (Solanum tuberosum L.) yield and soil quality in Yunnan Province, China.

Methods

Six treatments were set: calcium-magnesium phosphate fertilizer (M); M + biochar (MB); calcium-magnesium phosphate fertilizer + 50% of compound fertilizer (H); H + biochar (HB); calcium-magnesium phosphate fertilizer + 100% of the compound fertilizer (F); F + biochar (FB). Total yield per plot, commercial potato percentage, soil microbial community structure (determined via high-throughput sequencing), and soil physicochemical properties (including soil organic matter, ammonium-nitrogen, nitrate-nitrogen, available phosphorus (AP), available potassium (AK), soil sucrase, soil urease, and soil β-glucosidase) were measured at different potato growth stage.

Results

The yield, soil physicochemical properties and soil microorganisms’ structure under different fertilization treatments had significant difference. The highest potato production (43,095 kg/ha) was recorded in the HB treatment. HB treatment also altered the abundance and composition of the soil microbial community, resulting in more adsorbed fungi and a higher abundance of Proteobacteria and Bacteroidota. Furthermore, it was observed that biochar optimizes the rhizosphere microenvironment by specifically enriching Proteobacteria, functional bacterial genera (e.g. Advenella/Sphingobacterium), and Basidiomycota.

Conclusions

The combination of 3,000 kg/ha of calcium-magnesium phosphate fertilizer + 1,500 kg/ha of compound fertilizer + 1,500 kg/ha of biochar optimized the balance between potato yield and fertilizer cost, reducing agricultural waste while also improving SOM levels.
