Sometimes what science really needs is more bulls&$#.
Just ask a group of environmental scientists in China, who lost their 2019 article on soil contamination because what they thought was manure was in fact something else.
The article, titled “Immobilization of heavy metals in e-waste contaminated soils by combined application of biochar and phosphate fertilizer,” appeared in February in Water, Air, & Soil Pollution, and was written a team from the South China Institute of Environmental Science and Sun Yat-sen University, both in Guangzhou.
According to the researchers:
This paper reports the effects of single and combined application of biochar and phosphate fertilizer on immobilization of heavy metals in e-waste-contaminated soils. The results showed that combined amending biochar and phosphate fertilizer improved physical and chemical characteristics of soil but resulted in ammonium nitrogen loss. Biochar combined with phosphate fertilizer increased shoot biomass of lettuce while biochar applied alone could inhibit the growth of lettuce. A distinct decrease of heavy metal concentrations in lettuce was observed in phosphate fertilizer + biochar (3.0%) treatments while highest heavy metal concentrations in shoots and roots were observed in control treatments.
