After reading this article you will learn about the physical and chemical processes of weathering rocks and minerals. 1. Physical or Mechanical Weathering: The physical or mechanical weathering process may be defined as the process by which disruption of consolidated massive rocks into smaller bits was found without any corresponding chemical change or formation of new products. Under extreme climatic [...]
After reading this article you will learn about the influence of soil temperature on plant growth and nutrition. 1. Germination of Seeds: The germination of the different seeds is greatly influenced by the variation in soil temperature. If the temperature is too low, the seed fails to germinate or germinate at a slow rate. On the other hand, seeds may [...]
This article will guide you about how to calculate specific heat and heat capacity of soil. Specific Heat: Specific heat may be defined as the amount of heat required to raise the temperature of one gram of a substance by 1°C. The specific heat of dry soil (0.2 cal/g) is only about one-fifth that of water (1 cal/g). Hence, moist [...]
