It is the only nutrient which remains in the plant fluids in a soluble state. Nitrogen is an essential constituents of metabolically active compounds such as amino-acids, proteins, enzyme and some non-proteinaceous compounds. Soil Sci Soc Am . Soil tests can be used to assess whether there are useful potassium reserves at depth.It is true that once soluble potassium is taken up by plants from the soil, it is replaced by other pools of potassium in the soil, such as exchangeable potassium, held on to clays and organic matter, to reach a natural equilibrium. (2005) concluded in a literature survey that crop K concentrations are often well below (<2.5–3.5%). Nitrogen, phosphorus and potassium, or NPK, are the “Big 3” primary nutrients in commercial fertilizers. The nutrient value of Epsom salts is 0-0-0, meaning […] Potassium can be applied all year round (365 days) 6. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). The major source of potassium for plants in soils is from clay minerals (Velde and Barré, 2010) which are the most reactive inorganic components in soil systems (Barré et al., 2009). Potassium chloride (KCl) is available in three different grades, containing either 50%, 41%, 33% potassium per volume. This reflects the soil’s ability to hold K and other cations and store them in the soil for crop uptake. Manjaiah 1.
