The growth of plants depends upon the nutrients present in soil. The soil structure and nutrients present in it affects the root growth as well as leaves and fruits. Hence, analysis of soil composition and plant is essential. The plant nutrients present in soil is basically nitrogen (N), phosphorus (P2O5), potassium (K2O), humus content, total CaCO3, available lime, organic matter, total sulfur (S), Sodium, micro nutrients. The characteristics of soil as well as growth of plants depend upon water absorption capacity, pH, density, etc. This content describes analysis of various prime nutrients. This unit also contains analysis of various fuels including coal. The NCV and GCV are also explained.
