About the Book

In order to achieve sustainable and profitable yields of crops in agricultural planning, it is essential that information on the soil be collected to enable an assessment of the fertility and productivity of the land. A reasonable amount of information for evaluating the land is usually gathered in the field as field data and samples subjected to elaborate laboratory analyses. Manual of Soil, Plant and Water Analyses presents a series of carefully selected methods which reflect current pedagogy for obtaining information on important physical and chemical properties of soil, plant and water samples. It provides the necessary link between classroom, field and laboratory practices. This manual is recommended for use in soil testing laboratories, in higher institutions offering agricultural science, chemistry and biological science including those engaging in environmental and ecological studies especially environmental impact assessment. environmental monitoring and auditing, and water assessment.

Description

Preface

For proper development of a nation and control of the physical environment, information on soil, plant and water quality is very crucial. In developed countries with a high level of technology, information is needed by town and country planners at all levels of decision making. Information on soil is also needed for land allocation for residential, commercial, agricultural and recreational development.

For agricultural planning, it is very essential that the information on soil be collected for the assessment of fertility and the productivity of the land. This will lead to proper management of the soil for sustainable and profitable yields of crops. There is also the need to have information on the quality of the plants or crops grown in the soil in order to evaluate the fertility status of the soil. A reasonable amount of information for evaluating the land is usually gathered in the field as field data. However, most of the useful information needed for land evaluation is largely obtained in the laboratory after subjecting the samples of soils and plants collected in the field to elaborate laboratory analyses.

Water is one of the three sustainers of life and, like food and air, the other sustainers, the quality of water is crucial for its various uses. Good quality water is needed for domestic, agricultural and industrial uses. The required level of purity of water depends on the purpose for which the water is to be used. In order to assess the quality of water for any particular use, several parameters of the water have to be determined in the laboratory. The analytical data obtained from the laboratory for land evaluation and water quality assessment include physical, chemical and microbiological properties, but for plants, chemical and at times biological properties are needed.

This manual gives the analytical procedures for important physical and chemical properties of soil, plant and water samples. Microbiological assay is however not included in the manual. The methods described in the manual include volumetric, spectrophotometric  (or colorimetric), flame photometric and atomic absorption spectrophotometry which require  the use of spectrophotometers or colorimeters and photometers such as flame photometer and atomic  absorption spectrophotometer, which are generally available in most moderately equipped laboratories in Nigeria. A significant inclusion in this manual is a guide for pedological inferences from soil test data as well as a section to guide in the understanding of basic chemistry and application in samples analyses.

The manual is recommended for use in soil testing laboratories, the universities, polytechnics and colleges of education offering agricultural science, chemistry and biological sciences. It will also be found very useful for those engaging in environmental and ecological studies, particularly environmental impact assessment (EIA) and environmental monitoring and auditing, as well as water quality assessment. Some methods in soil analysis section are particularly useful for those carrying out research in Soil Chemistry and Soil Testing.
