2. Center-pivot irrigation - Wikipedia

   en.wikipedia.org/wiki/Center-pivot_irrigation

   A satellite image of circular fields characteristic of center pivot irrigation, Kansas Farmland with circular pivot irrigation. Center-pivot irrigation (sometimes called central pivot irrigation), also called water-wheel and circle irrigation, is a method of crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers.

3. Alternate wetting and drying - Wikipedia

   en.wikipedia.org/wiki/Alternate_wetting_and_drying

   A water tube/pipe made of PVC is usually used to practice AWD method. The main purpose of the tube is to monitor the water depth. The tube allows measuring water availability in the field below the soil surface. The usual practice is to use a pipe of 7–10 cm diameter and 30 cm long, with perforations in bottom 20 cm.

4. Chicken wire - Wikipedia

   en.wikipedia.org/wiki/Chicken_wire

   Chicken wire, or poultry netting, is a mesh of wire commonly used to fence in fowl, such as chickens, in a run or coop. It is made of thin, flexible, galvanized steel wire with hexagonal gaps. Available in 1 ⁄ 2 inch (about 1.3 cm), 1 inch (about 2.5 cm) diameter, and 2 inch (about 5 cm), chicken wire is available in various gauges —usually ...

5. Chlorinated polyvinyl chloride - Wikipedia

   en.wikipedia.org/wiki/Chlorinated_polyvinyl_chloride

   CPVC can withstand corrosive water at temperatures greater than PVC, typically greater by 40–50 °C (greater by 72–90 °F), contributing to its popularity as a material for water-piping systems in residential and commercial construction. CPVC maximal operating temperature peaks at 200 °F (93 °C).

6. Vinyl chloride - Wikipedia

   en.wikipedia.org/wiki/Vinyl_chloride

   Vinyl chloride that is released by industries or formed by the breakdown of other chlorinated chemicals can enter the air and drinking water supplies. Vinyl chloride is a common contaminant found near landfills. [4] Before the 1970s, vinyl chloride was used as an aerosol propellant and refrigerant. [5] [6]

7. Drip irrigation - Wikipedia

   en.wikipedia.org/wiki/Drip_irrigation

   Waste of water, time and harvest, if not installed properly. These systems require careful study of all the relevant factors like land topography, soil, water, crop and agro-climatic conditions, and suitability of drip irrigation system and its components. In lighter soils subsurface drip may be unable to wet the soil surface for germination.

   Buckminster­fullerene "Bucky ball" with a chicken wire-like chemical structure Chicken wireIn chemistry, the term chicken wire is used in different contexts. Most of them relate to the similarity of the regular hexagonal (honeycomb-like) patterns found in certain chemical compounds to the mesh structure commonly seen in real chicken wire.
