2. Leaf sensor - Wikipedia

   en.wikipedia.org/wiki/Leaf_sensor

   The agriculture sustainability benefits of water and energy savings have been established using the SG-1000 leaf sensor under field conditions and in greenhouses. Plant science researchers and agronomists have utilized the SG-1000 Leaf Sensor for studying the relationship between water content and leaf cell turgidity potential and leaf thickness.

3. Crop desiccation - Wikipedia

   en.wikipedia.org/wiki/Crop_desiccation

   Desiccated potato plants prior to harvest. Pre-harvest crop desiccation is the application of an agent to a crop just before harvest to kill the leaves and/or plants so that the crop dries out from environmental conditions, or "dry-down", more quickly and evenly.

4. Moisture meter - Wikipedia

   en.wikipedia.org/wiki/Moisture_meter

   Moisture meters are measuring instruments used to measure the percentage of water in a given substance, as physical properties are strongly affected by moisture content and high moisture content for a period of time may progressively degrade a material. Meters exist for various substances, including wood, building materials, concrete, and soil.

5. Soil moisture - Wikipedia

   en.wikipedia.org/wiki/Soil_moisture

   [20] [22] Once the available water is used up the remaining moisture is called unavailable water as the plant cannot produce sufficient suction to draw that water in. Wilting point The wilting point is the minimum amount of water plants need to not wilt and approximates the boundary between available and unavailable water. By convention it is ...

6. Soil moisture sensor - Wikipedia

   en.wikipedia.org/wiki/Soil_moisture_sensor

   A simple soil moisture sensor for gardeners. Soil moisture sensors measure the volumetric water content in soil. [1] Since the direct gravimetric measurement of free soil moisture requires removing, drying, and weighing of a sample, soil moisture sensors measure the volumetric water content indirectly by using some other property of the soil, such as electrical resistance, dielectric constant ...

7. Irrigation - Wikipedia

   en.wikipedia.org/wiki/Irrigation

   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.

8. Tensiometer (soil science) - Wikipedia

   en.wikipedia.org/wiki/Tensiometer_(soil_science)

   A tensiometer in soil science is a measuring instrument used to determine the matric water potential (soil moisture tension) in the vadose zone. This device typically consists of a glass or plastic tube with a porous ceramic cup and is filled with water .

9. Moisture stress - Wikipedia

   en.wikipedia.org/wiki/Moisture_stress

   Moisture stress is a form of abiotic stress that occurs when the moisture of plant tissues is reduced to suboptimal levels. Water stress occurs in response to atmospheric and soil water availability when the transpiration rate exceeds the rate of water uptake by the roots and cells lose turgor pressure .
