Other claims from this paper (14)
- Intervention effect BC2 biochar treatment increased the number of soil macroaggregates by 10.3% compared with CK.
- Intervention effect BC2 biochar treatment increased the average weight diameter of soil aggregates by 24.5% compared with CK.
- Observation Soil pH increased in all biochar treatments except BC1 relative to the initial 7.03.
- Observation The highest soil pH of 7.17 was recorded in the NPK and BC2 treatments.
- Intervention effect Biochar application increased soil organic carbon and total nitrogen content compared with CK and NPK treatments.
- Intervention effect The BC2 treatment improved soil C/N compared with CK.
- Intervention effect The BC2 treatment increased the copy number of soil bacteria by 25.6% compared with CK.
- Intervention effect The combined chemical fertilizer and biochar application improved soil mechanical composition and fine particle contents relative to NPK alone.
- Intervention effect Mixed biochar with chemical fertilizer increased the weight of 100 grains from 9.5% to 10.9% compared with CK.
- Intervention effect Biochar treatments with fertilizer gave higher maize yield than chemical fertilizer alone, in the order BC2 > BC3 > BC1 > NPK > CK.
- Intervention effect BC2 biochar treatment increased maize yield by 34.8%.
- Association Maize yield was significantly and positively correlated with soil aggregates, organic carbon and total nitrogen.
- Association Maize yield was significantly and positively correlated with 100-grain weight.
- Recommendation The authors recommend applying 31.50 t·hm−2 (BC2 treatment) of biochar to improve soil properties and maize yield.
