Modified biochar helps compost retain nitrogen and build richer soil organic matter
Researchers designed modified biochars with phosphorus and magnesium to improve compost quality by retaining nitrogen and accelerating humification. The study found that these materials reduced ammonia emissions and promoted microbial activity, resulting in higher nitrogen retention and improved soil fertility.
