Leaching Requirement of Soil Solution

STEP 0: Pre-Calculation Summary

Formula Used

Leaching Requirement = Electrical Conductivity of Irrigation Water/Electrical conductivity of Drained Water
LR = EC_i/EC_(d)
This formula uses 3 Variables

Variables Used

Leaching Requirement - (Measured in Milliliter per Day) - Leaching requirement the fraction of the irrigation water that must be percolated out of the bottom of the root zone in order to prevent average soil salinity from rising above some specifiable level.
Electrical Conductivity of Irrigation Water - (Measured in Siemens per Meter) - Electrical conductivity of irrigation water a measure of the ability of soil to conduct electrical current.
Electrical conductivity of Drained Water - (Measured in Siemens per Meter) - Electrical conductivity of drained water a function of time and irrigation water salinity under two leaching fractions.

STEP 1: Convert Input(s) to Base Unit

Electrical Conductivity of Irrigation Water: 1.2 Siemens per Meter --> 1.2 Siemens per Meter No Conversion Required
Electrical conductivity of Drained Water: 12 Siemens per Meter --> 12 Siemens per Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

LR = EC_i/EC_(d) --> 1.2/12

Evaluating ... ...

LR = 0.1

STEP 3: Convert Result to Output's Unit

1.15740740740741E-12 Cubic Meter per Second -->0.1 Milliliter per Day (Check conversion here)

FINAL ANSWER

0.1 Milliliter per Day <-- Leaching Requirement

(Calculation completed in 00.004 seconds)

What is the Leaching Process?

The process of leaching includes the partitioning of contaminants between a solid and liquid phase (e.g., assuming local equilibrium) coupled with the mass transport of aqueous or dissolved constituents.

Why is Soil Leaching important?

Leaching can transport chemical compounds like dissolved substances or larger materials such as decomposing plant materials, fine rock fragments, and microbes throughout the Critical Zone. In agricultural ecosystems, leaching is an important balance between preventing salt accumulation and removing nutrients from soil.

How to Calculate Leaching Requirement of Soil?

Leaching Requirement of Soil calculator uses Leaching Requirement = Electrical Conductivity of Irrigation Water/Electrical conductivity of Drained Water to calculate the Leaching Requirement, The Leaching Requirement of Soil formula is defined as the fraction of the irrigation water that must be percolated out of the bottom of the root zone in order to prevent average soil salinity from rising above some specifiable level. Leaching Requirement is denoted by LR symbol.

How to calculate Leaching Requirement of Soil using this online calculator? To use this online calculator for Leaching Requirement of Soil, enter Electrical Conductivity of Irrigation Water (EC_i) & Electrical conductivity of Drained Water (EC_(d)) and hit the calculate button.
