Web1 feb. 2024 · Abstract. Carbon (C) mineralization of crop residues is an important process occurring in soil which is helpful in predicting CO 2 emission to the atmosphere and nutrient availability to plants. A laboratory experiment was conducted in which C mineralization of residues of rice (Oryza sativa), wheat (Triticum aestivum), maize (Zea mays), mungbean … Web30 nov. 1999 · Estimates of a typical growing season contribution of N mineralization in the zero to six inches of topsoil range from 15 to 50 kg per hectare (13.5 to 44.5 lbs per acre), says Schoenau. For Black soils with high organic matter under no-till with legumes in the rotation, that contribution could be considerably higher than 50 kg.

As observed in many experiments, the principal mechanism is the production of mineral dissolving compounds such as organic acids, siderophores, protons, hydroxyl ions and CO2 ( Rodríguez and Fraga, 1999; Sharma et al., 2013 ).
Web12 apr. 2024 · Implications for Rare-Metal Mineralization. Granites from the Xihuashan and Yaogangxian plutons show convincing evidence of Li isotope fractionation with higher δ 7 Li values in the more evolved late-stage granites. We propose that the elevated δ 7 Li records intense magmatic differentiation, which promoted the mineralization of rare metals.
