1 lis 2019 · Field capacity (FC) is one of the most cited soil physical parameters and is relevant for the management of agricultural systems. In the search for alternatives to the estimation of FC, several researchers have proposed methods based on dynamic and static criteria.
Calculation: Use the weight of the soil at field capacity minus the dry weight of the soil to calculate the amount of water it holds at field capacity. Calculating 90% and 80% Field Capacity....
estimate field capacity. The work described in this paper was designed to develop a rapid method of determining the field capacity of irrigated soils, in the field, under conditions of crop growth. In addition, comparisons of moisture holding characteristics determined in 26 the laboratory with the field capacity as measured in the field, were made
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 2–3days after a rain or irrigation in pervious soils of uniform structure and texture.
FC (Field Water capacity) is amount of water in the soil held by sorption and capillary force (around 2.24 pF, 0.33 bar or 4.79 psi). On this water capacity all soil capillary pores (pores with...
24 maj 2014 · Soil regulation of internal drainage toward FC has long been recognized as producing a useful hydrologic benchmark for modeling and for estimation of plant available soil water.
Quirijn de Jong van Lier, ... Paulo Ivonir Gubiani, in Encyclopedia of Soils in the Environment (Second Edition), 2023. The upper limit of plant available water: Field Capacity. Field capacity (FC) is a concept originating from irrigation management and associated with the soil water content after major drainage has ceased.
