Biosolids are a by-product of the wastewater treatment process and can be used as fertilisers as they are rich in nitrogen and phosphorus. Photo: City of Geneva ATTRIBUTION-NONCOMMERCIAL 2.0 GENERIC CC BY-NC 2.0 DeedCity of Geneva ATTRIBUTION-NONCOMMERCIAL 2.0 GENERIC CC BY-NC 2.0 Deed

US bio-fertilisers are useful but watch out for contamination

,
Used as fertilisers, biosolids produced by wastewater treatment can be very beneficial for the soil. This is also why, according to a study, it is important to analyse their content to prevent contamination phenomena

Denmark bets on biochar for sustainable agriculture

, ,
Biochar in the spotlight: the Danish plan to cut agricultural emissions includes a huge EUR 1.35 billion investment. Chiaramonti (PoliTo): "This solution embraces economic competitiveness and will guarantee multiple benefits"

Organic farming affects plant genetics

,
A study by the University of Bonn shows how conventionally and organically grown barley plants develop differently. The latter experience adaptations in their genetic material
In China, the addition of biochar to agricultural soils has generally increased the organic carbon content of soil aggregates.

Here is how biochar promotes the sequestration of organic carbon

,
Biochar promotes the formation of soil aggregates and, with them, carbon sequestration, a research explains. In some Chinese farmland, the presence of the substance has increased by 60 per cent

This is how soil microbes fight plant infections

,
According to University of California Davis research, certain strains of soil microbes act on the roots of sorghum plants, protecting them from external threats

Cyanobacteria are amazing biofertilizers for soil

,
According to a U.S. study, cyanobacteria or "blue-green algae" can be used to produce a biofertilizer suitable for iron-poor soils, thus turning into a valuable natural resource for farmers
