Question
Chapter 20, Problem 4CGP
Interpretation Introduction
Interpretation: Thepercentage of N,P and K for different targeted plants such as roses, or indoor plants should be compared.
Concept introduction: Effect of Nitrogen on plants: It helps the plant in the process of photosynthesis and growth. It makes the plants strong and greener and also show rapid vegetative growth.
Effect of Phosphorus on the plants: Phosphorus is an essential element for plant growth and reproduction. It is also called as a major nutrient because it is utilized by plants in large quantity.
Effects of Potassium on plants: Potassium is used by plants to regulate the processes and it is also one of the most important elements plants need.
