The bangar soil has higher concentration of kanker nodules than the Khadar. It has more fine particles and is more fertile than the bangar. Alluvial soils as a whole are very fertile.]]> 2021-07-30 07:39:52 UTC https://padlet.com/20091925/486d9bt037e2k91v/wish/1664820196 20091925 https://padlet.com/20091925/486d9bt037e2k91v/wish/1664820604 potash

Black soil is formed by the weathering or breaking of igneous rocks and also by the cooling or solidification of lava from the volcano eruption. Therefore, it is also called lava soil. This soil is formed from rocks of cretaceous lava and is formed from the volcano eruption.]]> 2021-07-30 07:42:42 UTC https://padlet.com/20091925/486d9bt037e2k91v/wish/1664821864 20091925 https://padlet.com/20091925/486d9bt037e2k91v/wish/1664822482 the black soils are made up of clayey soil, well-known for their capacity to hold moisture. Because of their high clay content, black soils develop wide cracks during the dry season, but their iron-rich granular structure makes them resistant to wind and water erosion.]]> 2021-07-30 07:43:43 UTC https://padlet.com/20091925/486d9bt037e2k91v/wish/1664822482 20091925 https://padlet.com/20091925/486d9bt037e2k91v/wish/1664823188 calcium
