Why do plants not grow well in a barrenland?
Answers
Explanation:
Typically land will be barren of plants due to extreme dehydration of the soil. ... The middle of deserts, such as in the Saharah, and Gobi are bone dry, recieving very little infrequent rain, and thus don't support much plant life.
Typically land will be barren of plants due to extreme dehydration of the soil. This can be caused by several things:
Heavy compaction of soil, where the air spaces in the soil have been largely removed- such as in an area that has repetedly been driven on by cars or heavy machinery, or even just walked on, like a bare dirt foot path- can cause the soil to become impervious to water. The rain just immediately washes off it- down-hill and away, thus the soil remains hard and dry. Compacted soil is basically just like exposed rock, on which- if you think about it- you will barely ever see a plant growing.
The middle of deserts, such as in the Saharah, and Gobi are bone dry, recieving very little infrequent rain, and thus don’t support much plant life.
Salification of soil, due to heavy application of chemical fertilizers, or highly saline irrigation water, or else from salt deposits left over from ancient dried up inland seas, such as the salt flats of Arizona, makes uptake of water very difficult for plant roots, even if moisture is present in the soil, and can create barren conditions.
Other than that the only other possible cause i can think of would be sepentine soils, which contain high concentarionscof some toxic metal such as copper or aluminum- which can severely stunt of prevent plant growth. But even then there are some plants that have adapted to grow in such soils.
