Leaching Requirement of Soil Solution

Follow our step by step solution on how to calculate Leaching Requirement of Soil?

FIRST Step Consider the formula

LR = \frac{EC i}{EC (d)}

Next Step Substitute values of Variables

∴

LR = \frac{1.2S/m}{12S/m}

Next Step Prepare to Evaluate

∴

LR = \frac{1.2}{12}

Next Step Evaluate

∴

LR = 1.15740740740741E-12m³/s

LAST Step Convert to Output's Unit

∴

LR = 0.1mL/d
