Watertable control
In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage. Soil and watertable control are land management.
See Soil and Watertable control
Wax
Waxes are a diverse class of organic compounds that are lipophilic, malleable solids near ambient temperatures.
See Soil and Wax
Weathering
Weathering is the deterioration of rocks, soils and minerals (as well as wood and artificial materials) through contact with water, atmospheric gases, sunlight, and biological organisms.
Wetting
Wetting is the ability of a liquid to displace gas to maintain contact with a solid surface, resulting from intermolecular interactions when the two are brought together.
See Soil and Wetting
Wicking bed
A wicking bed is an agricultural irrigation system used in arid countries where water is scarce, devised by Australian inventor Colin Austin.
Wiley-Blackwell
Wiley-Blackwell is an international scientific, technical, medical, and scholarly publishing business of John Wiley & Sons.
Wood-decay fungus
A wood-decay or xylophagous fungus is any species of fungus that digests moist wood, causing it to rot.
See Soil and Wood-decay fungus
Woodlouse
Woodlice are terrestrial isopods in the suborder Oniscidea.
World Heritage Site
World Heritage Sites are landmarks and areas with legal protection by an international convention administered by UNESCO for having cultural, historical, or scientific significance.
See Soil and World Heritage Site
World Reference Base for Soil Resources
The World Reference Base for Soil Resources (WRB) is an international soil classification system for naming soils and creating legends for soil maps.
See Soil and World Reference Base for Soil Resources
World Soil Museum
The World Soil Museum (WSM) displays physical examples of soil profiles (monoliths) representing major soil types of the world, from the volcanic ash soils from Indonesia to the red, strongly weathered soils from the Amazon region.

Xenophon
Xenophon of Athens (Ξενοφῶν||; probably 355 or 354 BC) was a Greek military leader, philosopher, and historian, born in Athens.
Yangtze
Yangtze or Yangzi is the longest river in Eurasia, the third-longest in the world.
See Soil and Yangtze
Yellow River
The Yellow River is the second-longest river in China, after the Yangtze; with an estimated length of it is the sixth-longest river system on Earth.
Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30.
