Descripción
Integrated nutrient management is a well-accepted approach for the sustainable management of soil productivity and increased crop production. It utilizes well-equipped testing laboratories. These need information on a widely acceptable methodology that can ensure reasonable accuracy, speed and reproducibility of results. The method has to be readily comprehensible to those who need to apply it in a routine manner. This publication provides practical guidelines on establishing composite servi ce laboratories; information on the basics of an analytical laboratory; simple methods for estimating soil and plant constituents for assessing soil fertility and making nutrient recommendations; standard methods for estimating the parameters and constituents of irrigation water for assessing the quality; methods for analysing mineral fertilizers to judge their quality; methods for the isolation, identification, multiplication and commercial production of agriculturally useful microbial inocula nts; and details of the equipment, chemicals and glassware required for a given analytical capacity.
