Smart Plant Nutrition: Understanding NPK and Foliar Fertiliser Application

This practical, hands-on course introduces participants to the fundamentals of plant nutrition, focusing on the essential macronutrients — Nitrogen (N), Phosphorus (P), and Potassium (K) — and their critical roles in crop development. Learners will explore how each nutrient supports specific plant functions, from leafy growth to root development and fruit production.

Building on this foundation, the course then dives into foliar fertilizer application — a targeted technique for delivering nutrients directly through plant leaves. Participants will learn when and how to use foliar sprays effectively, understand best practices for mixing and applying fertilizers, and discover how this method can quickly correct nutrient deficiencies and improve crop performance.

By the end of this course, participants will be able to:

• Identify the roles and benefits of NPK macronutrients in plant growth.
• Recognize signs of nutrient deficiencies in crops.
• Understand the principles and advantages of foliar fertilizer application.
• Apply foliar sprays safely and effectively under various field conditions.
• Make informed decisions about fertilizer use based on crop needs and environmental factors.
