“Soil Chemistry, Soil Fertility and Nutrient Management” examines the chemical foundations of plant nutrition, soil reaction, nutrient transformation dynamics, soil fertility evaluation, and remediation of problem soils. Topics include essential elements, soil pH, N-P-K nutrient cycles, secondary and micronutrient dynamics, deficiency symptoms, soil testing, permanent manurial trials, and reclamation of saline, sodic, and acid soils.
