The effects of bentonite clay mixed with various nitrogen (N) fertilizers on NO3-1 leaching from sandy soils haven't been extensively studied. Therefore, the present lysimetric study determined NO3-1 leaching from bentonite [0, 2 and 4% (m/m)] treated sandy soil under three N sources (calcium nitrate [Ca(NO3)2], ammonium chloride [NH4Cl], and urea [CO(NH2)2] at the rate of 300 kg N ha-1). Results showed that bentonite markedly reduced NO3-1 release in the leachate, while 4% bentonite retained higher NO3 in the soil. The NO3-1 leaching from sandy soil varied with N sources as Ca(NO3)2 > NH4Cl > (CO(NH2)2. At early stages of leaching, higher concentrations of NO3-1 were detected in leachate with both NH4Cl and Ca(NO3)2, but leaching of NO3-1 increased with urea at later leaching stages. The amount of total NO3-1 retained in soil was conversely related to the amount of NO3-1 in the leachate. This study indicated that soil amendment with bentonite could efficiently mitigate NO3-1 leaching from sandy soil and hence prevent N fertilizer losses and groundwater pollution."],"journal":["PloS one"],"pagination":["e0278824"],"full_dataset_link":["https://www.ebi.ac.uk/biostudies/studies/S-EPMC9779043"],"repository":["biostudies-literature"],"pubmed_title":["Bentonite clay with different nitrogen sources can effectively reduce nitrate leaching from sandy soil."],"pmcid":["PMC9779043"],"pubmed_authors":["Cheng T","Khattak RA","Song D","Hussain Z","Yao C","Irshad M","Mohiuddin M"],"additional_accession":[]},"is_claimable":false,"name":"Bentonite clay with different nitrogen sources can effectively reduce nitrate leaching from sandy soil.","description":"Nitrate (NO3-1) leaching from soils results in the lower soil fertility, reduced crop productivity and increased water pollution.
