After reading this article you will learn about the chemistry and behaviour of phosphorus present in soil. Chemistry of Phosphorus: 1. Sorption Reactions: The surfaces on which phosphate ions enter into sorption reactions of two types-surfaces of constant charge e.g. crystalline clay minerals and surfaces of variable charge including Fe3+ and Al—oxides and organic matter where H+ and OH- ions [...]
After reading this article you will learn about:- 1. Content of Potassium in Soil 2. Sources of Potassium in Soil 3. Forms 4. Deficiency. Content of Potassium in Soil: A large portion of total K in soils comes from the K-bearing and crystal lattices of silicate minerals. The micas (muscovite and biotite) and the feldspars (orthoclase and microcline) constitute the [...]
After reading this article you will learn about the role of phosphorus in relation to metabolic functions, nutrition and growth of plants. The role of phosphorus as a constituent of macro molecular structures is the most prominent in nucleic acids as units of DNA molecule which carry the genetic information and as units of RNA which are responsible for the [...]
