Abstract:
... Bioremediation based on microbial induced carbonate precipitation (MICP) was conducted in Cd-contaminated seleniferous soils with objective to investigate effects of MICP on the fates of Cd and Se in soils. Results showed that soil indigenous microorganisms could induce MICP process to stabilize Cd and mobilize Se without inputting exogenous urease-producing strain. After remediation, soluble Cd ( ...

Abstract:
... The effect of reaction between soil and phosphate on pH has not previously been explored or explained. We incubated samples of a soil with calcium carbonate to give a range of pHCaCl2 from 4.2 to 7.2, and then measured the change in pH when these samples were reacted with phosphate solutions. These solutions were at the same pH as the soil to which they were added. We also measured exchangeable ca ...

Abstract:
... To increase soybean actual yields (Yₐ), modern farmers are interested in exploring novel intensification options. We hypothesize that the inclusion of a high-input treatment in high-productivity systems may potentially reduce yield gaps (Yg), representing additional profits for farmers. Our objectives were to: (i) estimate Yₐ, water-limited yield potential (Ywₗᵢₘ), and Yg; (ii) evaluate a high-inp ...
