Technical Abstract: Soils throughout the world are diverse, and plants grown on them often encounter mineral stress problems. The nature of mineral stress problems that plants encounter may depend on many soil chemical [acidity and alkalinity (pH), sodicity and salinity, mineral nutrient deficiencies and toxicities, organic matter] and physical [moisture, temperature, bulk density, texture] properties. Each of these factors has specific influences on type and severity of mineral stresses that plants encounter. This paper reviews mineral nutritional constraints associated with acidic and alkaline soils. That is, hydrogen, aluminum, manganese, iron, and trace element toxicities and phosphorus, calcium, magnesium, molybdenum, potassium, nitrogen, sulfur, silicon, zinc, boron, and iron deficiencies associated with acidic soils and phosphorus, iron, zinc, manganese, copper, boron, and molybdenum deficiencies and boron, sodium, and chlorine toxicities associated with alkaline soils are reviewed. Distribution of acidic and alkaline soils throughout the world and description of mineral nutritional deficiency/ toxicity symptoms on plants are included.
