What crops grow best in volcanic soil?
Volcanic soils are ideal for vegetable production (“market gardening”) because of the high subsoil macroporosity. This encourages root vegetables including potatoes, carrots, onions, turnips and swedes, to expand without limit in a freely drained subsoil environment.
Is volcanic ash good for farming?
In countries with active volcanoes, volcanic ash (tephra) is a more feasible, nature-based solution for soil improvement and CO2 reduction. Because tephra can capture and store carbon, tephra-derived soils—Andisols (or Andosols)—are some of the most fertile and carbon-rich mineral soils in the world.
How do plants grow after a volcanic eruption?
The ash and magma from the eruption can also be very rich in nutrients essential for plant growth, so the soil around volcanoes is often some of the most fertile on the planet. Seeds are carried to the soil by wind and animals, and eventually the volcano may be covered by dense vegetation.
How do plants grow on volcanic islands?
But on lava flows, where plant life has to start again from scratch, the process is much slower. Nooks, crannies, and crevices can collect dirt, water, and seeds. Eventually, ferns and other plants can start to grow. But for soil to form on the top of the lava flow, the rock has to weather down.

How does volcanic activity affect the atmosphere?
In general it is proposed that volcanic activity put so much ash and/or gas into the atmosphere that the earth’s temperature either got too hot for the dinosaurs or got too cold for the dinosaurs . It sounds kind of funny that either can happen but it is true. If the ash particles are really small (<2 microns) then they block out incoming sunlight and the earth gets cool. If they are bigger than 2 microns (but still pretty small) then they let sunlight in but don’t let heat radiation from the surface out, and the earth gets warm.Anyway, if you have enough large explosive eruptions, then the theory says that there will be enough ash in the stratosphere to have one of these effects. You need an eruption (or series of eruptions) that is much bigger than anything we have ever witnessed. The reason that you need to put the ash into the stratosphere is that if it is only in the troposphere (where weather clouds are), then it will get rained out very quickly and it won’t be around long enough to have a climatic effect.
How does an eruption affect an insect?
The impact of eruptions on insects depends on the size of the eruption and the stage of growth of the insect. For example, ash can be very abrasive to wings.
