Soil is the main source of nutrients for crops. Soil also provides support for plant growth in various ways. Knowledge about soil health and its maintenance is critical to sustaining crop productivity. The health of soils can be assessed by the quality and stand of the crops grown on them. However, this is a general assessment made by the farmers. A scientific assessment is possible through detailed physical, chemical and biological analysis of the soils.
This publication provides various analytical methods for estimating soil constituents with the objective of assessing soil fertility and making nutrient recommendations. Traditional soil testing techniques, including chemical, physical and microbiological methods, are complemented by the most suitable modern methods. It will be a highly valuable text for all those concerned.
