After reading this article you will learn about the potassium and ammonium fixation in soils. Cation fixation in soils occurs when exchangeable or water soluble cations are converted to a form that cannot be readily extracted with a neutral solution of a salt. Potassium (K+) and ammonium (NH4+) ions have been primarily involved in such reactions. Fixation of NH4+ takes [...]
After reading this article you will learn about the anoxygenic and oxygenic photosynthesis. The Anoxygenic Photosynthesis: Anoxygenic photosynthesis uses energy from sunlight to couple the reduction of C in CO2 to the anaerobic oxidation of S in S0 or H2S. If one is accustomed to thinking of S oxidation in a strictly aerobic sense, then anaerobic S oxidation appears contradictory. [...]
This article throws light upon the six main factors that affect phosphate fixation in soil. The factors are: 1. Nature and Amount of Soil Components 2. pH 3. Other Ions 4. Organic Matter 5. Temperature 6. Over Liming. Factor # 1. Nature and Amount of Soil Components: Adsorption and desorption reactions are affected by the type of surfaces contacted by [...]
