Antique Dutch windmills used to pump water into the embanked river to prevent waterlogging of the lowlands behind them. Waterlogging water is the saturation of soil with water. [1] Soil may be regarded as waterlogged when it is nearly saturated with water much of the time such that its air phase is restricted and anaerobic conditions prevail.
Carex lyngbyei is a species of sedge known by the common name Lyngbye's sedge.It is native to the west coast of North America from Alaska to California, where it "is the common sedge of the Pacific coastal salt marshes."
Irrigation (also referred to as watering of plants) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world.
Underwater logs are safe from many of the forces which cause decomposition, including fungi. Log salvage operations began in the early 20th century across the United States. John Cayford and Ronald Scott's book Underwater Logging describes the process and prospects for retrieving sunken wood from American waterways, known as salvage logging. [4]
Waterlogging or water logging may refer to: Waterlogging (agriculture), saturation of the soil by groundwater sufficient to prevent or hinder agriculture; Waterlogging (archeology), the exclusion of air from an archeological site by groundwater, preserving artifacts; Underwater logging, the process of harvesting trees that are submerged under water
Keep plant in a moderately bright area with cool to intermediate temperatures from 45F to 90F. [2] To induce blooming reduce watering for 3 to 4 weeks during the winter. Keep humidity at 60 to 80%. The plant is easy to flower. Pot in a mix of bark, perlite, and charcoal. [2] Variations including coconut husk chips are also used.
Pores (the spaces that exist between soil particles) provide for the passage and/or retention of gasses and moisture within the soil profile.The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water.

It is also known as available water content (AWC), profile available water (PAW) [2] or total available water (TAW). The concept, put forward by Frank Veihmeyer and Arthur Hendrickson, [3] assumed that the water readily available to plants is the difference between the soil water content at field capacity (θ fc) and permanent wilting point (θ ...
