NPK Ratio: The ratio of Nitrogen (N), Phosphorus (P), and Potassium (K) in soil or fertilizer. These are the three macronutrients essential for plant survival and growth.
Monitoring NPK is critical. If smart farming systems detect that water content is too high, there is a risk of NPK leaching away from the root zone, effectively throwing expensive fertilizer down the drain.
