Composting biochar improves its effects (#journal)
It is claimed that biochar addition to soil improves C sequestration to prevent CO2
from atmospheric cycling. Biochar addition should also increase soil
fertility in a similar way as anthropogenic dark earths of Central
Amazonia. Previous studies have shown that biochar stimulates plant growth, especially when biochar is combined with
organic fertilizers such as compost. However, little is known about
optimum addition amounts and mixture ratios of biochar and compost.This study considered optimum biochar and compost amounts and mixture
ratios with respect to plant response and soil fertility. Results show that biomass production was increased with
rising biochar and compost amounts. The positive
influence of composted biochar on plant growth and soil properties
suggests that composting is a good way to overcome biochar’s inherent
nutrient deficiency, making it a suitable technique helping to refine
farm-scale nutrient cycles.
