Macronutrients
Macronutrients are the essential elements that plants need in large quantities to grow healthy and produce good yields. In vertical farming, these mainly include nitrogen, phosphorus, and potassium (often called NPK). Think of them as the main ingredients in a plant's diet. Understanding and managing macronutrients is crucial for indoor farming operations because, unlike traditional farming where soil naturally contains these elements, in vertical farming systems, growers need to carefully add and monitor these nutrients in their water-based growing solutions.

Example Interview Questions
Senior Level Questions
Q: How would you develop a nutrient management strategy for a new vertical farm facility?
Expected Answer: A strong answer should cover creating detailed feeding schedules, monitoring systems, staff training programs, and emergency response plans for nutrient imbalances. They should also mention cost management and environmental impact considerations.
Q: What factors do you consider when adjusting macronutrient ratios for different crop types?
Expected Answer: The candidate should discuss plant growth stages, environmental conditions, water quality, crop-specific needs, and how to interpret plant health indicators to make informed adjustments.
Mid Level Questions
Q: How do you identify and correct common nutrient deficiencies in plants?
Expected Answer: Should explain visual symptoms of different nutrient deficiencies, testing procedures, correction methods, and preventive measures to avoid future issues.
Q: Explain how you would maintain proper nutrient levels in a recirculating hydroponic system.
Expected Answer: Should discuss monitoring tools, testing frequency, adjustment procedures, and the importance of maintaining proper pH and EC levels for nutrient availability.
Junior Level Questions
Q: What are the main macronutrients plants need and why are they important?
Expected Answer: Should be able to identify nitrogen, phosphorus, and potassium (NPK) and explain their basic roles in plant growth and development.
Q: How do you measure nutrient levels in a hydroponic solution?
Expected Answer: Should describe basic testing equipment like EC and pH meters, when to test, and normal ranges for common crops.
