Soil Fertility Around Volcanoes

Why do people live by active volcanoes?

  • The soils around the volcano are fertile.
  • People will be able to grow a variety of crops.
  • (Rich soil) encourages farming, agriculture and population growth.
  • By-products of volcanic activity can be used in everyday applications.
  • Volcanic ash us used as a filler in adhesives, and great for construction use.
  • Beneficial products of volcanic activity are that the earth (soil) will be filled with nutrients.
  • Thermal energy, used to produce electricity.
  • Prime petroleum sources.
  • High-energy geothermal systems most efficient natural concentrators of valuable ore minerals.

How do volcanoes make soil fertile?

  • Soil Fertility is rich in nutrients like zinc, chlorine, iron, cobalt, nitrogen, boron, and many more.
  • Lava coming down the side breaks down slowly to form fertile soil, which holds lots of water.
  • The ash from the volcanoes can be good because it releases valuable nutrients that will make the soil more fertile.
  • Climate plays a huge role because good soil depends on the precipitation to get growth in the vegetables.
  • Not all volcanic soil is rich because hydrogen ions could be released instead and become more acidic, which will be harder for plants to grow.
  • Over the years the minerals from lava and ash will be broken down more but it could be or not be beneficial to the soil.

Volcanic Soil, Ash, Water

  • Volcanoes soil are also know as andisols. Andisols are formed from volcanic ash.
  • Volcanic materials break down and weather to form some of the most fertile soils on Earth.
  • Volcanic ash often contain minerals that are beneficial to plants, and if it is very fine ash it will break down quickly and get mixed into soil.
  • Volcanic soils contain small amounts of iron witch plants need to make chlorophyll.
  • Volcanoes make soil fertile because magmatic soil/material contain many many different kinds of nutrients that aid farming and agriculture.
  • Volcanic ash is hard,rough, and does not dissolve in water. It can conduct electricity when it is wet.
