Nutrient Mass Delivery Rate

What is this formula?

The Nutrient Mass Delivery Rate equation calculates the mass of nutrient delivered per unit time through an irrigation or fertigation system.

When to use it

Use this formula to determine how much nutrient is being supplied to crops, verify fertigation schedules, and size fertilizer injection systems.

Example

A fertigation system injects nutrient solution at:

Q = 150 L/h

Nutrient concentration:

C = 0.040 kg/L

Formula:

Mr = Q × C

Substitution:

Mr = 150 × 0.040

Mr = 6 kg/h

Result:

The system delivers nutrients at a rate of 6 kg/h.

Applications

- Fertigation system design

- Nutrient delivery calculations

- Fertilizer injector sizing

- Greenhouse crop management

- Precision agriculture

Note

This equation assumes that the nutrient concentration remains constant throughout the application period. In practical systems, concentration may vary due to tank mixing conditions, injector performance, or changes in stock solution composition.
