“…The application of lime@1% increased the Ex + WSCr fraction relative to the case where no amendment was applied.With the increase in contact period, a Cr salt solution would react with soil and revert to a less available and more insoluble form. Our results agree with the results reported bySinduja et al 2022 in which they concluded that the application of FYM at a rate of 12.5 t ha − 1 caused a reduction in the water-soluble Cr fraction from 95.53 mg kg − 1 to 82.25 mg kg − 1 during 60 days of incubation under eld capacity moisture conditions. The application of 10% sulfonated peat reduced the amount of water-soluble, exchangeable, and acid-soluble Cr by 90%(Hou et al 2020).…”

An experiment was carried out to study the effect of farm yard manure (FYM) and lime addition on the distribution of native and added chromium among various soil chromium (Cr-VI) fractions, namely exchangeable and water soluble (Ex + WS), carbonate bound (CARB), easily reducible oxides (ERO's), organic matter bound (OM), reducible oxides (RO's), and residual (RES) fractions of non-contaminated surface soil. The study was performed with three different treatments (FYM@1%, lime @1% and no amendment) and for eight contact periods (1, 3, 7, 21, 42, 63, 84, and 105 days). The overall trend in Cr fractions shows that a more significant proportion of native Cr was associated with the residual fraction, followed by reducible oxide and organic matter fractions. The lowest concentration of Cr was observed to be in the exchangeable fraction. The addition of different concentrations of Cr increased the Cr content in each fraction with a higher increase in more labile fractions (water-soluble + exchangeable) at a lesser contact period, and further transformation of Cr to relatively lesser available fractions was observed with the increase in the time of contact.

The accumulation of heavy metals in soil and plant tissue is a serious concern since it impacts both soil quality and food safety. This study evaluated the accumulation of heavy metals and the food quality of lettuce as a result of the application of chemical fertilizer (CF) and bioslurry (BS). The treatments were CF (158 kg ha−1 NPS and 200 kg ha−1 urea), BS (5 ton ha−1), and control with no fertilizer, laid out in a randomized complete block design with three replications. Soil samples were analyzed for their physico‐chemical characteristics. The concentrations of 10 heavy metals (As, Pb, Zn, Cd, Cu, Ni, Co, Fe, Mn, and Cr) in the agricultural soil, bioslurry, and lettuce tissue were determined. Both the BS and CF reduced the concentrations of most heavy metals in the agricultural soil, particularly As, Pb, and Cd. Only the mean concentration of Cd in the agricultural soils exceeded the threshold level set by WHO/FAO (2011) for agricultural soils. Similarly, the concentration of As, Pb, and Cd in lettuce tissue grown in BS‐treated soils and the concentration of As in agricultural soils surpassed the limit set for vegetables. Given the toxicities of As, Cd, and Pb, as well as the effect on food safety, human health, and the environment, it is unsafe to cultivate lettuce using either the agricultural soil or BS in the study area.
