Soil Fertility and Nutrient management (1+1)

Problems of alkali soils on plant growth

•  Poor water and air permeability as a result of high dispersion of soil aggregates and clay particles.
•  Low availability of water due to poor conductance from the lower soil layers.
•  Seedling emergence & germination is greatly affected due to hard crust surface.
•  Seed bed preparation is very difficult because it does not come to proper moisture conditions.
•  Deficiency of Ca and there is an antagonistic effect on K and Ca nutrition.
•  Toxic concentration of HCO3- and CO32- ions.
•  Decreased solubility of Fe & Zn.
•  Increased solubility and accumulation of toxic elements such as F, Se & Mo in plants that may affect crop yield.
