NewsPairing biofertilizers with biochar turns farm and city waste into climate-smart soil solutions
A new review makes the case that organic waste from farms, cities and industries could become a resource for healthier soil and more resilient farming — if two waste-derived soil treatments, microbial biofertilizers and biochar, are used together rather than separately.

NewsBiochar can act as an ‘interface engineer’ to reshape the hidden world around plant roots
A new review shows how biochar simultaneously modifies soil structure, chemistry and microbial communities in the rhizosphere, offering a framework for more precise and sustainable agricultural use.

NewsBiochar as an “electron bridge” unlocks hidden power of energy‑saving wastewater treatment
New research reveals how a charcoal‑like material triples electron transfer capacity in ammonia‑removing microbes, cutting wastewater treatment costs by up to 90%.

NewsBiochar made from brewery waste could help trap harmful bacteria in sandy filtration systems
Researchers have found that biochar made from a common brewery byproduct can substantially improve the ability of sand to retain Escherichia coli, pointing to a potential new use for brewing waste in water filtration and groundwater protection.

NewsOxygen nanobubbles turn biochar into an active defense against cadmium in flooded rice soils
A newly engineered biochar maintained oxygen around rice roots, shifted cadmium into more stable soil forms, and substantially reduced cadmium accumulation in rice plants.
-
NewsBiochar ‘switches on’ natural oxygen chemistry to suppress soil-borne pathogens and reshape healthier microbial communities
A new study reveals how specially prepared biochar can directly suppress a destructive soil-borne pathogen while helping rebuild a richer and more stable soil bacterial community.
-
NewsBiochar and smarter water management could help make rice safer in polluted soils
A new study suggests that pairing iron and manganese modified biochar with carefully chosen irrigation strategies can reduce cadmium and mercury buildup in rice, offering a practical path toward safer food production in co-contaminated paddy fields.

NewsBiochar helps paddy soils lock away carbon by reshaping microbial life underground
A new study reveals that straw and biochar both increase soil organic carbon, but biochar stores carbon more efficiently by guiding soil microbes toward stable carbon formation.
-
NewsBiochar-coated catalyst turns wet microalgae into cleaner fuel-building chemicals
Turning microalgae into usable liquid fuels remains difficult because algae-derived bio-oil often contains high levels of oxygen and nitrogen compounds. A new study reports a promising strategy to address this challenge.

NewsMicrobes hold the key: unlocking sustainable carbon storage in farmland with biochar
New analysis reveals how soil bacteria and fungi govern biochar’s effectiveness in Chinese agriculture, guiding optimized carbon sequestration strategies
-
NewsNanozeolite-coupled biochar fertilizer may help bamboo forest soils hold on to carbon
A new study finds that a biochar-based phosphate fertilizer can reduce soil carbon loss and lower the temperature sensitivity of carbon decomposition in Moso bamboo forests.
-
NewsRice husk biochar catalyst breaks down antibiotic pollutant in minutes
A new biochar supported cobalt oxide catalyst rapidly removes levofloxacin from water while revealing a key reaction mechanism for cleaner wastewater treatment.

NewsHow biochar helps soil carbon last longer: microbes turn dissolved organic matter into more stable forms
A long-term field study reveals that biochar does more than add carbon to soil. Over time, it can reshape microbial activity and help transform dissolved organic matter into more humified, stable carbon pools.

NewsFungi help biochar and compost lock more carbon in nutrient-poor urban soils
A new field study shows that soil fungi can determine whether urban greenspace amendments build long-term soil carbon or accelerate carbon consumption.
-
NewsBiochar’s hidden electron power could unlock cleaner pollution control and energy recovery
A new review highlights how biochar’s natural redox properties may help overcome key barriers to large-scale environmental applications.
-
NewsBiochar triggers a five-year soil recovery cascade in acidifying rice paddies
A long-term field study reveals how biochar reshapes soil chemistry, microbes, viruses, and metabolites to support healthier agricultural ecosystems.
-
NewsTwo types of biochar help alfalfa survive salty soils
A new study shows that carefully designed biochar can guide plant metabolism and reshape beneficial microbial communities around the roots to help reduce stress from saline-alkali soil.
-
NewsBiochar and beneficial microbes team up to restore polluted soils and boost crop growth
A new review examines how biochar-immobilized microbes can help clean contaminated soils, improve soil health, and support crop growth. By analyzing evidence from 92 published studies, the authors provide a data-driven overview of how this technology works and what is needed to bring it closer to practical use on farms.

NewsWarming may weaken biochar’s climate benefits in cropland soils, global study finds
Researchers found that warming significantly increased carbon dioxide emissions from soils treated with biochar by an average of 77%. The effect was especially strong in croplands, where emissions increased by 117.5%, compared with 30.9% in forest soils.
