Analysis of soil and plant samples is an important tool for assessing plant nutrient need for formulation of crop and site-specific nutrient recommendations for higher economic return as well as to minimize risk of environmental pollution . . . This laboratory manual entitled Manual on Advanced Techniques for Analysis of Nutrients and Pollutant Elements in Soil, Plant and Human covering methodologies for assessing status of nutrients and pollutant elements in soil-plant-human continuum, their distribution in different soil fractions, and protocols for risk assessment of polluted soils provides a timely and needed updates of new and simplified analytical procedures available today .
