After reading this article you will learn about the chemistry of hydrogen and aluminium in the development of soil acidity. It is evident that hydrogen and aluminium both contributes soil acidity. Hydrogen ions contribute soil acidity directly while aluminium ions do so indirectly through hydrolysis. Therefore, it is essential to know the chemistry of aluminium for the development of soil [...]
After reading this article you will learn about the nature and sources of soluble salts found in soil. Nature of Soluble Salts: Soluble salts, as referred to in soil science, are those inorganic chemicals that are more soluble than gypsum (CaSO4.2H2O), which has a solubility of 0.241 gm. per 100 ml of water at 0°C. Common table salt (NaCl) has [...]
After reading this article you will learn about the synchronous cultures of bacteria. Synchronous cultures are composed of populations of cells that are at the same stage of their life cycle. All the cells in the culture will divide at the same time will grow for a generation time, and all will divide again at the same time. Thus the [...]
