This book describes some proven and widely used methods for the detemination of plant nutrients and quqlity parameters in soils, plant, waters, fertilisers and organic manures/composts. In the various chapters, all essenital plant nutrients are covered, except CI. Thus methods are described mainly for N, P, K, S, Ca, Mg, B, Cu, Fe, Mn, Mo and Zn.

For samples of materials other than soils, methods described are for total nutrient content. In the case of soils, methods described are for their available nutrient status as is done in most soil testing laboratories. The relevance of water analysis travels beyondb its suitability for irrgation and also covers the environmental and pollution aspects as well. Thus the description covers anions, cations, nutrients, salinity parameters, BOD, COD and microbial aspects.
