  1. Field capacity

    Field capacity is the amount of soil moisture or water content held in soil after excess water has drained away and the rate of downward movement has materially decreased, which usually takes place within 2–3 days after a rain or irrigation in pervious soils of uniform structure and texture. The physical definition of field capacity is the bulk water content retained in soil at −33 J/kg of hydraulic head or suction pressure. The term originated from Israelson and West and Frank Veihmeyer and Arthur Hendrickson. Veihmeyer and Hendrickson realised the limitation in this measurement and commented that it is affected by so many factors that, precisely, it is not a constant, yet it does serve as a practical measure of soil water-holding capacity. Field capacity improves on the earlier concept of moisture equivalent by Lyman Briggs. Veihmeyer & Hendrickson proposed this concept as an attempt to improve water use efficiency for farmers in California during that time [during what time??]. Field capacity is characterised by measuring water content after wetting a soil profile, covering it and monitoring the change in soil moisture in the profile. Water content when the rate of change is relatively small is indicative of when drainage ceases and is called Field Capacity, it is also termed drained upper limit.
