Physico Chemical Analysis of Soil, Water, and Plant

Soil, water, and air contain all of the essential elements in varying proportions, some in vast amounts. The elements essential for plants can be divided into those required in relatively large amount (the macronutrients) and those required in small amounts (the micronutrients). Soils properties vary from spot to spot and differ in their suitability for plant growth. Suitability of soil properties and the capacity of the soil to provide the required elements in adequate and balanced manner for plant growth are investigated by soil tests.
