Field Capacity of Water Solution

STEP 0: Pre-Calculation Summary

Formula Used

The Field Capacity of Water = (Unit Weight of Water*Depth of Root Zone in Meters)/The Dry Unit Weight of Soil
F = (Γ_w*d_w)/Γ_d
This formula uses 4 Variables

Variables Used

The Field Capacity of Water - The field capacity of water remaining in a soil after it has been thoroughly saturated and allowed to drain freely, usually for one to two days.
Unit Weight of Water - (Measured in Newton per Cubic Meter) - Unit Weight of Water is a volume-specific quantity defined as the weight per unit volume of a material.
Depth of Root Zone in Meters - (Measured in Meter) - Depth of root zone in meters is the depth within the soil profile that commodity crop (cc) roots can effectively extract water and nutrients for growth.
The Dry Unit Weight of Soil - (Measured in Newton per Cubic Meter) - The Dry unit weight of soil when the dry weight is reckoned with reference to the total original volume V, it is called the dry unit weight.

STEP 1: Convert Input(s) to Base Unit

Unit Weight of Water: 9.807 Kilonewton per Cubic Meter --> 9807 Newton per Cubic Meter (Check conversion here)
Depth of Root Zone in Meters: 0.3 Meter --> 0.3 Meter No Conversion Required
The Dry Unit Weight of Soil: 13.73 Kilonewton per Cubic Meter --> 13730 Newton per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F = (Γ_w*d_w)/Γ_d --> (9807*0.3)/13730

Evaluating ... ...

F = 0.214282592862345

STEP 3: Convert Result to Output's Unit

0.214282592862345 --> No Conversion Required

FINAL ANSWER

0.214282592862345 ≈ 0.214283 <-- The Field Capacity of Water

What is Field Capacity?

Field capacity is the amount of soil moisture or water content held in the soil after excess water has drained away and the rate of downward movement has decreased. This usually takes place 2–3 days after rain or irrigation in pervious soils of uniform structure and texture. The physical definition of field capacity (expressed symbolically as θfc) is the bulk water content retained in soil at −33 kPa (or −0.33 bar) of hydraulic head or suction pressure. The term originated from Israelsen and West[1] and Frank Veihmeyer and Arthur Hendrickson.[2]

What are the Physical Properties of Soil?

Physical properties of soil include color, texture, structure, porosity, density, consistence, aggregate stability, and temperature. These properties affect processes such as infiltration, erosion, nutrient cycling, and biologic activity.
