The large woody root traces can transport water and clay using their large pipes. They are efficient at moving soil into a subsurface horizon when the plant dies and the roots decay.

An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 and 6,000 metres (9,800 and 19,700 ft).Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth's surface.
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
[3] [4] Khadir soil consists of new alluvial soil relatively higher in new silt content from the river, gets replenished with each flooding cycle, and is often very fertile. [ 4 ] The Khadir is also called Nali in the northern Haryana which is the fertile prairie tract between the Ghaggar river and the southern limits of the Saraswati channel ...
The main ores of commercial interest are polymetallic nodules, which are found at depths of 4–6 km (2.5–3.7 mi) primarily on the abyssal plain. The Clarion–Clipperton zone (CCZ) alone contains over 21 billion metric tons of these nodules, with minerals such as copper , nickel , and cobalt making up 2.5% of their weight.
Soil texture triangle showing the USDA classification system based on grain size Map of global soil regions from the USDA. For soil resources, experience has shown that a natural system approach to classification, i.e. grouping soils by their intrinsic property (soil morphology), behaviour, or genesis, results in classes that can be interpreted for many diverse uses.
Depending the specific source of these concretions, they vary in an infinite variety of forms that include disc-shapes; crescent-shapes; watch-shapes; cylindrical or club-shapes; botryoidal masses; and animal-like forms. They can vary in length from 2 in (5.1 cm) to over 22 in (56 cm) and often exhibit concentric grooves on their surfaces.
The Liverpool Plains are an extensive agricultural area covering about 12,000 km 2 (4,600 sq mi) of the north-western slopes of New South Wales in Australia. These plains are a region of prime agricultural land bounded to the east by the Great Dividing Range , to the south by the Liverpool Range and on the west by the Warrumbungle Range .
