About this book

With the help of this guide, you can use obtained test results to evaluate the fertility status of soils and the nutrient element status of plants for crop production purposes. It serves as an instructional manual on the techniques used to perform chemical and physical characteristic tests on soils. Laboratory Guide for Conducting Soil Tests and Plant Analysis describes the basis and procedures for each test in detail, including analytical instrumentation procedures and laboratory quality assurance requirements.
