A five-year field experiment in alkaline paddy soil shows that long-term biochar amendment promotes nitrogen-conserving DNRA in deep layers while suppressing denitrification and anammox. Subject of Research: Effects of long-term biochar amendment on nitrate reduction pathways in deep alkaline paddy…
A soil amendment study found that a zinc-modified rice husk biochar pyrolyzed at 600°C was the most effective material for stabilizing cadmium in a contaminated calcareous soil.
A two-year field trial in China's coastal saline soils found that adding straw or biochar to manure raised soil organic carbon through distinct mechanisms, with straw boosting labile carbon and microbial necromass and biochar improving aggregates and pore structure. Subject…
A ten-year Chinese field trial shows biochar and maize stover build soil organic carbon through distinct molecular pathways, with biochar favoring long-term stable storage and stover driving active microbial carbon cycling. Subject of Research: Divergent soil carbon sequestration pathways of…
Loading redox-active manganese onto biochar boosted soil DNRA rates 2.9-fold and cut nitrous oxide emissions in a 22-day paddy soil incubation study. Subject of Research: Manganese-loaded biochar enhancing electron shuttling to promote dissimilatory nitrate reduction to ammonium in paddy soil…
A Chinese pot experiment found that wheat straw biochar immobilized soil zinc most effectively while peanut shell biochar best stabilized cadmium, with both metals reduced in Brassica chinensis and soil enzyme activity improved. Subject of Research: A pot experiment comparing…
A two-season field trial in a karst paddy in Southwest China shows biochar-based amendments cut rice grain cadmium by up to 85.4 percent while raising grain selenium by up to 357.5 percent. Subject of Research: Biochar-based soil amendments for simultaneous cadmium immobilization…
Using high-resolution sampling in cadmium (Cd)-contaminated soil, researchers show that within just a few millimeters of biochar, soil chemistry shifts dramatically, reducing Cd bioavailability and... Microscale âCharosphereâ Around Biochar Particles Cuts Cadmium Uptake in Wheat Figure 5 Principal component analysis…
A two-season cardoon experiment found that fungal inoculation and deficit irrigation altered leaf phenolic compounds, flavonoids and measured antioxidant activity, with their interaction affecting nine of ten compounds studied. An experimental study of cardoon leaves found that arbuscular mycorrhizal fungi…
The chemistry of soils: nutrients, carbon stored in soil, contaminated land and the chemistry of restoring it.
