Although subject to fertility loss, saline soils represent an important agricultural reserve when treated with appropriate restoration techniques. A recent Chinese study examines them
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
