State the importance of rock to agriculture
Answers
Answer:
I think that here we are talking about rocks as parent rocks (unweathered rocks below the surface) and how these rocks affect the soil above them and indirectly the crops’ quality. For example, loess is a porous rock so it can retain water readily available for the plant roots in the soil, consequently the yields will be high. So wherever there is loess, the soil above it becomes fertile and it is considered a good agricultural land.
Or on volcanic rocks similarly good soil will develop, especially if these rocks are pyroclastic (i.e. tuff) because due to their nature they are full with gas bubble pores or little holes. It again can hold water below the soil.
In addition to this, when the underlying rocks start to weather underground (disintegrate due to moisture or growing roots), a lot of minerals will be released into the soil making it more fertile.
Rocks and minerals can be found all around us, and they help with the development of new technology as well as being employed in our daily lives.
In agricultural science, what is rock?
- Any mineral substance found on Earth is classified as rock.
- Rocks make up the Earth's crust.
- A rock can be made up of a variety of mineral components, such as silicon and oxygen-containing silica.
- Soils are formed as a result of the weathering of rocks.
- Rocks provide almost all of the building materials needed in the construction of roadways, floors, and house walls.
- They are a source of valuable metals such as gold, platinum, and other similar metals.
- Minerals in the soil act as both sources and sinks of important plant nutrients.
- When primary minerals weather in soils, they release plant nutrients that were originally created at high temperatures and pressures in igneous and metamorphic rocks.
